If you went through DARE in the 1990s or early 2000s, you heard about PCP. You probably heard about it more than you heard about drugs you were actually likely to encounter.
The presentations always had the same energy. A cop or a former user would stand at the front of your classroom or auditorium and tell you about angel dust. About people ripping their eyes out. About superhuman strength. About a guy who thought he could fly and jumped off a building. About naked people running through traffic, impervious to pain, requiring six officers to restrain them. The message was clear: PCP was the drug that made you lose your mind in the most spectacular, violent, irreversible way possible.
And then you graduated, and you never saw it. Not at parties, not in college, not in the real world where people actually used drugs. You saw weed, alcohol, cocaine, MDMA, psychedelics, opioids. But PCP? It had vanished like it was never really there in the first place.
So what happened? How did a drug go from being America’s “number one drug problem” in 1978 to something most people under 40 have never even been offered? This is the story of a pharmaceutical mistake that became a street drug, triggered a moral panic, and then disappeared almost as quickly as it arrived.
The Accidental Discovery
PCP was first discovered in 1926 by a German chemist named Arthur Kötz and his student Paul Merkel, created as a byproduct of a completely different chemical reaction. They were working on a completely different project, when PCP emerged as an unexpected product. At the time, nobody knew what to do with it. The molecule was noted, documented, and filed away. It sat in chemistry literature for three decades, just another molecule in a world full of molecules, waiting for someone to figure out what it was good for.
That someone was Victor Maddox, a chemist working for Parke-Davis pharmaceutical company who synthesized it again in 1956. This time, it wasn’t an accident. Parke-Davis was actively searching for new anesthetic agents, and PCP looked promising on paper. Pharmacologist Dr. Graham Chen and his associates received the compound from Maddox in September 1957 and began testing it on animals.
The early animal studies were striking. In rodents, PCP caused an excited, drunken state. But in pigeons, it produced something entirely different: a cataleptoid, immobilized state. This unusual pharmacology, where the same drug produced opposite effects in different species, caught the attention of researchers. It suggested that PCP was doing something unique to the nervous system, something that didn’t fit the existing categories of drugs.
The researchers were amazed enough that they brought in Dr. Maurice Seevers, Head of Pharmacology at the University of Michigan, as a consultant. The drug’s profile was that unusual. It was then that the research moved toward human trials.
The drug was developed as a general anesthetic because it could achieve analgesia and anesthesia with minimal cardiovascular and respiratory suppression. That was huge. Most anesthetics at the time came with significant risks. Ether was flammable and caused severe nausea. Chloroform could damage the liver and heart. Barbiturates could suppress breathing to dangerous levels. Later anesthetics had better safety profiles, but they still required careful monitoring of vital signs.
PCP didn’t do that. It put you under without shutting down the basic machinery that kept you alive. Your heart kept beating at a normal rate. Your blood pressure stayed stable. Your breathing continued without mechanical support. For surgeons and anesthesiologists, this was potentially revolutionary. It meant they could focus on the surgery rather than constantly managing the patient’s vital signs.
In 1963, it began to be used in surgical procedures under the trade name Sernyl. For a brief window, it looked like Parke-Davis had developed a miracle drug. Patients went under cleanly. Their vital signs stayed stable. Surgeons could do their work without constantly monitoring for respiratory failure or cardiac events. The drug was working exactly as intended during the procedure.
Then the patients woke up.
The Problem with Sernyl
The early researchers who tested PCP in the 1950s noticed something strange about its effects: it caused the central nervous system to be isolated from peripheral sensory input. Essentially, your brain got disconnected from your body. You were still conscious in some sense, but you couldn’t process what was happening to you. The term they used was “dissociative anesthetic,” which would later define an entire class of drugs.
That dissociation turned out to be a feature during surgery. The problem was what happened after.
By 1967, PCP was discontinued for medical use in humans due to high rates of side effects, including postoperative dysphoria and hallucinations. Patients would wake up terrified, confused, or psychotic. Some experienced delirium that lasted hours. Some had vivid, disturbing hallucinations. About 15 percent of patients had what was described as postoperative psychosis.
One former resident who volunteered for a PCP study in the research phase still recalled her experience decades later as intensely psychologically painful. When the researchers administered PCP to medical students and psychiatric residents to document its effects, few were willing to take it a second time. That should have been the first warning sign. When people who understand pharmacology and are intellectually curious about drug effects don’t want to repeat the experience, you’re dealing with something unpleasant.
After 1967, PCP was limited to veterinary use, where it continued to be used as an anesthetic for animals until 1978, when it was discontinued entirely. By that point, Parke-Davis had developed something better: ketamine. Ketamine offered the same dissociative anesthetic properties without the severe psychiatric side effects. It was shorter-acting, more controllable, and patients didn’t wake up thinking they were dead or being chased by demons. PCP became medically obsolete.
But it didn’t disappear. It just moved to the street.
The Street Drug Emerges
PCP began to emerge as a recreational drug in the 1960s, with the first reports of abuse appearing in Haight-Ashbury, San Francisco, the epicenter of the hippie movement. This was the peak of psychedelic culture, a time when people were actively seeking out mind-altering experiences. LSD, psilocybin, mescaline, and cannabis were the drugs of choice for people chasing consciousness expansion, mystical experiences, or just a different way of seeing the world.
PCP didn’t really fit that mold. It wasn’t a classical psychedelic. It didn’t produce the colorful visuals, the sense of unity with the universe, or the introspective clarity that people sought from acid or mushrooms. What it produced was dissociation, confusion, numbness, and a sense of being fundamentally disconnected from reality.
That made it an odd choice for the peace-and-love crowd. But it had a few things going for it: it was cheap, it was easy to make, and it was available. The drug is fairly easy and cheap to manufacture, which meant that small-scale clandestine labs could produce it without the sophisticated chemistry required for LSD or the agricultural infrastructure needed for cannabis or natural psychedelics.
And for some people, the effects were appealing. Users reported feelings of strength, power, and invulnerability, along with a numbing effect that could suppress unpleasant emotions or memories. If you were living on the margins, dealing with trauma or pain, that emotional anesthesia had value. It wasn’t enlightenment, but it was escape.
The delivery method that made PCP stick was smoking. Once it was discovered that PCP could be sprayed onto tobacco or cannabis and smoked, it gained more adherents, as smoking offered some rudimentary control over the dose and effects. You could take a hit, see how you felt, and decide whether to take another. That was harder to do with pills or liquid that you’d swallowed and committed to for the next several hours.
By the early 1970s, PCP use had spread beyond San Francisco to other major cities. The resurgence of PCP in the 1980s was localized to certain metropolitan areas including Baltimore, Chicago, Detroit, Los Angeles, New Orleans, New York City, San Diego, San Francisco, St. Louis, and Washington, DC. It became a distinctly urban drug, concentrated in specific neighborhoods and social networks.
The Peak: 1970s
PCP use peaked in the United States in the 1970s, with surveys showing that 13 percent of high school seniors reported trying PCP at least once in 1979. That’s a staggering number when you think about it. More than one in ten teenagers had experimented with a drug that was already known to cause psychotic breaks.
The 1970s were a unique moment in American drug culture. The 1960s get most of the credit for permissiveness, but the average American remained relatively uptight throughout that decade. The full cultural ripple effect of the 1960s counterculture didn’t take hold until the late 1970s, which became the most permissive era in the nation’s history. Deviant behavior that would have been shocking a decade earlier was now normalized or at least tolerated. Drug use wasn’t just accepted in certain subcultures, it was openly celebrated in mainstream spaces.
Part of what drove PCP’s prevalence was the same thing that drives any drug trend: availability, social acceptance within certain groups, and the sense that “everyone’s doing it.” In the neighborhoods and social networks where PCP had taken hold, it became part of the fabric of social life. You saw your friends using it. You heard about it at parties. It stopped being “that scary drug” and became “the thing people do.”
But part of it was also misrepresentation. PCP was often sold as other drugs to save on production costs, including LSD, THC, mescaline, and even cocaine. Many drug users were unknowingly exposed to PCP because it was used as an adulterant in marijuana, LSD, and methamphetamine. If you thought you were buying acid and got PCP instead, you were in for a very different and potentially much worse experience. You’d prepared yourself mentally for an LSD trip, with its visual distortions and emotional intensity. Instead, you got dissociation, confusion, and possibly paranoia. The set and setting were wrong. The expectations were wrong. The experience could be traumatic.
This bait-and-switch aspect of PCP distribution contributed to its bad reputation. People who would never have chosen to try PCP ended up taking it accidentally, had terrible experiences, and warned everyone they knew to stay away from it. But by that point, the damage was done. They’d already added to the statistics.
The street names proliferated. Angel dust, hog, peace pill, rocket fuel, ozone, shermans, wack, crystal, embalming fluid, love boat, elephant tranquilizer, tic-tac, sherm sticks, wet. The names reflected both the drug’s effects (angel dust, love boat, peace pill) and its reputation (elephant tranquilizer, embalming fluid). Some of the names made it sound appealing, almost whimsical. Others made it sound like exactly what it was: a veterinary anesthetic that didn’t belong in human bodies.
The drug came in multiple forms. PCP is available as a powder, crystal, liquid, and tablet. That versatility made it easy to distribute and use in different contexts. The most common method was dipping cigarettes or joints into liquid PCP, creating what were called “dippers” or “sherm sticks.” You could smoke them like a regular cigarette, which made the drug feel less intimidating and more socially integrated into existing smoking culture. It looked like smoking weed or tobacco, activities that were already familiar and relatively normalized.
The liquid form also made it easy to disguise. A small bottle of PCP liquid looked innocuous. It could be transported easily, distributed quickly, and used to lace hundreds of cigarettes. For dealers, it was an efficient product. For users, it offered flexibility in dosing, at least in theory. You could dip lightly for a mild effect or saturate the cigarette for a stronger experience.
But the experiences people had on PCP were often not what they expected or wanted. According to the National Institute on Drug Abuse, most people who try PCP once say they would never want to use it again. The dissociation could be frightening. You could feel like you were watching yourself from outside your body, like your consciousness had been disconnected from the physical world. The loss of coordination and cognitive function could leave you vulnerable. You couldn’t walk straight, couldn’t think clearly, couldn’t protect yourself if something went wrong. The potential for paranoia, hallucinations, and psychotic reactions made every use a gamble. You never knew if this time would be the time you lost touch with reality completely.
Despite that, a subset of users kept coming back. The drug is addictive, both psychologically and physically. Some people used it regularly, going on what they called “runs” or “sprees,” using the drug for two or three days in a row, hardly eating or sleeping. They’d smoke dipper after dipper, chasing a state that was less about pleasure and more about obliteration. The slang term for PCP addicts was “dusters,” and some of them reported that they continued seeking the drug primarily because of physical addiction, the way your body adjusts to a substance and punishes you when you stop. Others craved the emotional numbness, the way PCP could turn off feelings that were too painful to bear sober.
For people dealing with trauma, with life circumstances that felt unbearable, that numbness had value. PCP didn’t make you happy. It didn’t give you energy or confidence like stimulants. It didn’t provide the warm comfort of opioids. What it did was make you not care. And for some people, in some situations, that was enough.
The Moral Panic: 1978
And then the media found it.
In 1978, People magazine and Mike Wallace of the TV news program 60 Minutes called PCP the country’s “number one drug problem”. That designation was remarkable given that heroin, cocaine, and alcohol were all more widely used and causing more deaths. But PCP had something those drugs didn’t: spectacular, photogenic horror stories.
The 60 Minutes segment aired in 1977, when Mike Wallace told a national audience that PCP was second only to heroin as the most dangerous drug. At the time, 60 Minutes had a Nielsen rating of 29.6, meaning 45 percent of all TVs turned on in the country were tuned into the program. That kind of reach is almost unimaginable now, in the era of fragmented media. Nearly half the country heard the same message at the same time: PCP is uniquely dangerous.
In the segment, a doctor claimed that children as young as nine years old were pooling their quarters together to buy PCP and smoking it at recess. Whether or not that was actually happening in any significant way is debatable, but the image was powerful. Elementary school kids smoking angel dust on the playground. It was the kind of story that demanded a response.
The coverage emphasized violence. Although studies by the Drug Abuse Warning Network in the 1970s showed that media reports of PCP-induced violence were greatly exaggerated and that incidents of violence were unusual and often limited to individuals with reputations for aggression regardless of drug use, the narrative took hold. PCP users were portrayed as unpredictable, superhuman, and dangerous.
In a 1980 essay called “The Dusting of America: The Image of PCP in the Popular Media,” researchers analyzed over 300 newspaper articles on PCP from the late 1970s and documented the frequency of popular horror stories. The stories followed a pattern: user takes PCP, user does something violent or self-destructive, user is impervious to pain or requires massive force to subdue. The tropes became so standardized that they were almost clichés.
The narrative was that PCP gave users superhuman strength and made them jump off buildings, with attitudes reflecting that it was a killer drug best avoided. In the 1984 film The Terminator, when Arnold Schwarzenegger’s character punches through a windshield suffering no pain, the police presume he must be high on PCP. That’s how deeply the mythology had embedded itself in popular culture.
The fact that the anti-PCP panic emerged in the late 1970s, during a time when American culture was loudly in favor of recreational drug use, made the fear campaign even more effective. This wasn’t the uptight establishment warning you away from fun. This was happening during the most permissive drug era in American history, when even drug users were saying, “No, not that one.” That gave the warnings credibility.
In 1978, PCP was transferred from Schedule III to Schedule II under the Federal Controlled Substance Act, reflecting the growing perception that it was among the most dangerous drugs available. In 1978, all legal manufacture of PCP was stopped in the United States, though illegal production continued.
Why the Panic Stuck
The PCP moral panic was different from other drug scares because it came with enough real incidents to make the exaggerations feel plausible.
Yes, media reports of PCP-induced violence were greatly exaggerated. Yes, incidents of violence were unusual and often limited to individuals with reputations for aggression regardless of drug use. But “unusual” doesn’t mean “never.” There were documented cases of people on PCP doing genuinely bizarre and dangerous things.
At Harper Hospital, one chronic PCP user whose psychosis manifested in outbursts of rage virtually destroyed the seclusion room. At Children’s Hospital, a doctor reported seeing two or three PCP poisonings per month, many involving severe behavioral disturbances. Emergency room workers had a saying: “Naked running is PCP until proven otherwise”. Those suspected of using the drug were treated as unhinged, out of control, and potentially lethal.
The problem is that PCP’s effects are dose-dependent and highly variable between individuals. Low to moderate doses of 1 to 5 milligrams can cause feelings of detachment, slurred speech, and loss of coordination, while doses greater than 10 milligrams usually result in mild coma, and doses of 25 milligrams or more can result in deep coma, convulsions, and even death. There is a poor relationship between PCP intoxication and blood serum concentration, meaning we have a limited understanding of safe doses.
Add to that the fact that PCP production was unregulated and often done in poorly controlled clandestine labs, meaning users were frequently unaware of the actual dose they were taking, and you had a recipe for unpredictable outcomes. Someone might smoke a dipper thinking they were getting a mild buzz and instead end up in a full-blown dissociative crisis.
The dissociation itself was part of what made PCP frightening to bystanders. Users could experience severe changes in body image, loss of ego boundaries, paranoia, and depersonalization. PCP can cause hypertension and tachycardia, and in rare cases, cardiac arrest has been reported. The drug has a sedative effect and should never be mixed with other depressants such as alcohol, benzodiazepines, or opioids, as this can increase risk of coma and dangerously lower heart rate and breathing.
But the most disturbing feature, from a public safety perspective, was the analgesia. PCP is an anesthetic. It blocks pain. This can lead users to hurt themselves, either intentionally or without knowing, and may mean they do not seek appropriate help for an injury. If you’re injured but can’t feel it, you keep going. If police try to restrain you and pain compliance techniques don’t work, the interaction escalates.
That’s where many of the horror stories came from. Not superhuman strength, but the absence of the feedback mechanisms that normally stop people from hurting themselves or others. Pain is a brake. Remove the brake, add paranoia or hallucinations, and you get the kind of incidents that made the news.
The Decline: 1980s and Beyond
Although recreational use of PCP had always been relatively low, it began declining significantly in the 1980s. In surveys, the number of high school students admitting to trying PCP at least once fell from 13 percent in 1979 to less than 3 percent in 1990. In just over a decade, use dropped by more than 75 percent.
Several factors drove that decline.
First, the reputation. PCP had a well-deserved bad reputation, even among drug abusers. Word of mouth spread. People saw what happened to users. They heard the stories from friends who’d had terrifying experiences. The drug became culturally coded as something that marked you as either desperate or reckless. Even in communities where drug use was normalized, PCP carried stigma.
Second, PCP was displaced in large measure by the widespread availability and use of crack cocaine in the 1980s. The crack epidemic hit American cities like a tidal wave. Crack became available in major cities for as little as $2.50 per dose, making it accessible to people who couldn’t afford powder cocaine. Between 1984 and 1987, cocaine-related incidents increased to 94,000, and by 1987, crack was reported to be available in all but four states.
Crack offered something PCP didn’t: a short, intense, euphoric high. It was reinforcing in a way that made people want to use again immediately. It was also cheaper and more available in many markets. Drug dealers and users shifted their attention. According to a former homeless heroin user who lived on the streets of Baltimore in the 1990s, PCP was drowned out by the explosion of heroin and cocaine use in the city over the 1980s and 1990s.
Third, there was a better alternative for people who wanted dissociative effects. Ketamine became popular in the 1990s among young adults at dance clubs and raves in combination with other club drugs, and was placed in Schedule III as a controlled substance in 1999. Ketamine is in the same category of dissociative anesthetic drugs as PCP, but you don’t get the stories about people thinking they can lift a ten-ton truck or the rage that got written about with PCP. Ketamine is more introspective and less threatening.
For people seeking dissociation, ketamine was a cleaner, shorter-acting, more controllable option. It came with its own risks, but it didn’t have the same reputation for inducing violent psychosis. It fit better into recreational contexts like clubs and music festivals. And crucially, it had continued medical legitimacy, which meant that pharmaceutical-grade ketamine was sometimes available through diversion, offering a known purity and dose that street PCP never could.
Fourth, the cultural moment had shifted. Ronald Reagan’s administration swept drug users into jail, and the nation threw away the pro-drug sentiment of the 1970s in favor of “Just Say No” campaigns. The War on Drugs ramped up enforcement, increased penalties, and created a climate where drug use became riskier legally and socially. In that environment, a drug with PCP’s reputation was an easy target for law enforcement and an easy thing for users to avoid.
Where PCP Went: The Geographic Puzzle
Here’s the strange part: PCP didn’t disappear everywhere.
Despite becoming a much more niche drug at a national level since the 1980s, PCP is still an intrinsic part of the drug scene in some parts of the United States, particularly Washington DC, Philadelphia, Los Angeles, San Diego, Houston, and Kansas City.
In Washington DC, PCP is the most frequently mentioned illegal substance in criminal case hearings at the city’s Superior Court after cocaine. Over a quarter of DUI tests in DC come up positive for the drug, and more than a third of arrestees who test positive for any drug have PCP in their system, the highest rate in the United States.
In Philadelphia, a narcotics officer reported that PCP is nearly as available as marijuana, with street sales mostly among low-income customers across all racial groups. The drug is typically smoked via $20 PCP-soaked cigarettes called “dippers”.
PCP use cuts across all racial groups, although it is especially prevalent in certain predominantly Black neighborhoods and low-income areas. According to a 25-year-old user from Philadelphia, it’s a drug people smoke while hanging out on street corners and at house parties, and not something you see people maintaining a professional life using in their spare time.
Why did PCP persist in these specific cities while vanishing from others? A drug worker compared it to different clothing brands being popular in different cities, suggesting it’s a matter of learned taste, availability, and supply and demand. Drug markets have their own local cultures. Once a drug becomes established in a network, it can self-perpetuate even as national trends shift.
The degree of PCP abuse in a metropolitan area may be related to the availability and cost of other, more highly coveted drugs. In cities where crack, heroin, or methamphetamine dominate, PCP fades. In cities where those drugs are less available or more expensive, PCP fills a niche.
PCP production and distribution is still largely centered in Los Angeles, with most of the nation’s supply manufactured and distributed by Los Angeles-based street gangs and affiliates, who transport it to secondary source cities via buses, trains, airlines, and private vehicles.
PCP is not just a drug of big cities; it can be found in small cities across the US, seemingly at random. In some Pennsylvania towns outside Philadelphia, PCP use is widespread among young people in areas with high unemployment and poverty. Police report that users are often brought to law enforcement attention because someone calls in a naked person in public, typically sweaty and paranoid.
The Current Picture
As of 2022, about 0.7 percent of 12th-grade students in the United States reported using PCP in the prior year, while 1.7 percent of people over age 25 reported using it at some point in their lives. Those are remarkably low numbers compared to the 13 percent of high schoolers who reported trying it in 1979.
A study of hallucinogen use from 2002 to 2019 reported an overall decline in PCP use during this timespan, especially among adolescents and young adults. The trend is clearly downward. The kids aren’t using PCP. The adults who tried it decades ago mostly stopped. What’s left is a small, geographically concentrated population of chronic users.
But there was a blip. Between 2005 and 2011, there was an increase in emergency department visits as a result of PCP, rising from 14,825 visits in 2005 to 75,538 in 2011, an increase of more than 400 percent. The largest increase was seen in patients aged 25 to 34.
In 2011, 72 percent of PCP-related emergency department visits involved PCP used in combination with other drugs such as marijuana, cocaine, and anxiolytics. That polysubstance pattern is important. People weren’t just using PCP. They were combining it, which made the effects more unpredictable and more dangerous.
That spike in emergency visits suggests that while overall prevalence is low, the people who are using PCP are using it in ways that lead to medical crises. Data from hospitals serving DC shows that around one in four people admitted for drug overdoses test positive for PCP. These aren’t casual users. These are people deep in a pattern of use that’s putting them in the ER repeatedly.
Why America and Not Anywhere Else
PCP is almost uniquely an American drug. It never gained significant traction in Europe, Asia, or anywhere else. That’s unusual. Most drugs spread globally once they become popular somewhere. Cocaine, heroin, cannabis, MDMA, methamphetamine, they all crossed borders. PCP stayed local.
One theory is that the UK and other countries already had ketamine as a PCP alternative, which is more popular in Britain than anywhere else. The rise of ketamine on the British clubbing scene in the 2000s may have made drug users less inquisitive about its more threatening American cousin.
Another factor is the reputation. In the 1990s, there were a lot of scare stories coming out of the United States about PCP users being terrifyingly strong, with massive libidos and frighteningly aggressive temperaments. Those stories traveled. If you’re a drug user in Europe hearing about a drug that makes people violent and psychotic, and you already have access to ketamine or other dissociatives that don’t carry that baggage, why would you seek out PCP?
The media coverage that was meant to scare Americans away from PCP also ensured that no one else wanted to try it. The moral panic was so effective that it essentially quarantined the drug within the communities where it was already established.
What PCP Actually Does
Let’s step back from the mythology and talk about what PCP actually does in the body and brain.
PCP works primarily as an NMDA receptor antagonist, blocking the activity of glutamate at NMDA receptors in the brain. Glutamate is the brain’s main excitatory neurotransmitter, involved in learning, memory, and synaptic plasticity. When you block NMDA receptors, you interrupt normal glutamate signaling, which produces the dissociative effects.
PCP also acts as a dopamine D2 receptor partial agonist and inhibits dopamine reuptake, leading to increased extracellular dopamine levels. That dopamine activity is likely responsible for some of the euphoric and reinforcing effects, as well as the potential for psychotic symptoms at higher doses.
The dissociation people experience on PCP is distinct from the altered states produced by classical psychedelics. There were aspects of the PCP subjective experience and the behavioral and cognitive changes it induced that were remarkably consistent with the psychopathology of some forms of schizophrenia. One researcher reported that phencyclidine was the only drug capable of producing the specific behavioral abnormalities of chronic schizophrenia in normal people.
That’s both fascinating and disturbing. PCP doesn’t just alter perception. It temporarily produces something that looks and feels like a psychiatric disorder. For researchers studying schizophrenia, PCP became a useful tool for creating animal and human models of psychosis. For recreational users, it meant they were playing with a drug that could make them functionally psychotic.
Studies on rats showed that PCP can cause reversible brain changes in certain regions, and there is evidence that chronic use may lead to cognitive deficits in attention, memory, and executive function. Long-term PCP use has been associated with problems with speech, thinking, and memory.
A 2019 review found that the transition rate from PCP-induced psychosis to schizophrenia was 26 percent. That’s higher than amphetamine, opioid, alcohol, or sedative-induced psychoses, though lower than cannabis-induced psychosis. If you have a PCP-induced psychotic episode, there’s about a one in four chance you’ll later develop schizophrenia. Whether the PCP triggered an underlying vulnerability or the psychotic episode itself increased risk is unclear, but either way, it’s not a trivial concern.
The Harm Reduction Gap
One of the stranger aspects of PCP’s history is how little harm reduction infrastructure developed around it.
With other drugs, there are established practices. Naloxone for opioid overdoses. Benzos for stimulant comedowns. Test kits for MDMA purity. Safer injection supplies. Educational materials. PCP never got that ecosystem, partly because use declined so dramatically and partly because the drug’s reputation made it hard to talk about in anything other than condemnatory terms.
As PCP production is unregulated, it is difficult to know the exact dose being taken. There are no test kits widely available to check purity or identify adulterants. There’s no reversal agent for PCP overdose, no equivalent to naloxone. Treatment is supportive: manage the symptoms, keep the person safe, wait for the drug to clear.
PCP can be addictive, and chronic users may find it difficult to give up, developing higher tolerance and needing increasingly higher doses. Withdrawal symptoms include high body temperature, seizures, agitation, muscle twitching, and hallucinations. Those are serious withdrawal effects, comparable to alcohol or benzodiazepine withdrawal, yet there’s little public awareness of them and limited treatment protocols specifically for PCP dependence.
The people who are still using PCP are often marginalized, dealing with poverty, homelessness, or involvement in the criminal justice system. It is likely that official figures on PCP use underestimate its true prevalence because it is a drug largely used by a socially excluded population living off the radar. These are the people least likely to have access to healthcare, harm reduction services, or drug treatment.
The Cultural Memory
Here’s what’s strange about PCP’s place in drug history: everyone remembers it, but almost no one has encountered it.
If you’re under 40, PCP exists primarily as a cultural artifact. It’s a punchline. It’s a reference in rap lyrics. It’s the drug they warned you about in DARE that you never actually saw in real life. In the 1980s New York hardcore punk scene, “dust” was a well-used stage name, and PCP has been referenced by rap musicians such as the Wu-Tang Clan. In 2014, rapper Andre Johnson, a Wu-Tang associate, cut off his genitals while high on PCP in Los Angeles, reinforcing the mythology of the drug’s capacity for inducing extreme self-harm.
But for most people, that’s where the knowledge ends. It’s folklore. The drug that made people think they could fly. The drug that gave you superhuman strength. The drug that turned you into a dangerous lunatic. None of those things are entirely false, but they’re not entirely true either, and the exaggeration obscures the actual risks.
The reality is more mundane and more tragic. PCP is a drug that produces profound dissociation, unreliable effects, significant addiction potential, and a high probability of psychiatric and medical complications. It’s not that different from other dangerous drugs except in one key way: it never developed a romanticized narrative or a cultural identity that made it appealing to new users.
Cocaine had glamour. Heroin had artistic mystique. MDMA had rave culture. Even methamphetamine found a foothold in certain communities. PCP’s identity was always “the drug that ruins you,” and that identity became self-fulfilling.
What We Can Learn
The rise and fall of PCP offers a few lessons that are worth extracting.
First, medical mistakes can have long tails. PCP was abandoned by medicine in 1967, but we’re still dealing with the consequences of its brief pharmaceutical career more than 50 years later. Once a drug enters circulation, especially a drug that’s easy to synthesize, it’s hard to make it disappear completely.
Second, media narratives matter. The 1978 panic around PCP was based on real incidents, but the exaggeration and sensationalism created a feedback loop that both increased fear and, perversely, may have increased curiosity among certain populations. The same coverage that was meant to deter use also publicized the drug and created a mythos around it.
Third, drug markets adapt. When PCP’s reputation made it undesirable, users shifted to crack and other alternatives. When ketamine became available, it filled the dissociative niche more safely. Markets aren’t static. They respond to availability, price, reputation, and user preferences.
Fourth, geography matters more than we often acknowledge. PCP didn’t decline uniformly. It vanished from some cities and persisted in others. Understanding why certain drugs take hold in certain places while failing to establish themselves elsewhere could inform more targeted interventions.
And finally, the people still using PCP, decades after it fell out of fashion, are the ones who need support the most. They’re not the casual experimenters or the weekend warriors. They’re chronic users, often dealing with polysubstance dependence, often marginalized and disconnected from healthcare systems. The fact that PCP use is now concentrated among the most vulnerable populations means that the harm reduction gap is hitting the people who can least afford it.
The Enduring Absence
So whatever happened to PCP? It fell victim to its own reputation, was displaced by better and worse alternatives, and retreated into geographic and social pockets where it lingers as a relic of a different drug era.
For most of America, PCP is gone. You won’t see it at parties. You won’t be offered it by a dealer. You won’t stumble across it accidentally. It exists now primarily in the DARE presentations that keep getting delivered to new generations of kids, perpetuating its mythology long after the drug itself has faded from relevance.
But in certain neighborhoods in DC, Philadelphia, and a handful of other cities, people are still smoking dippers. Still ending up in emergency rooms. Still cycling through the criminal justice system. The drug that America declared its number one problem in 1978 is now so marginal that most people forget it still exists.
That marginality doesn’t mean the harm is gone. It means the harm is concentrated, hidden, and easy to ignore.
