If you searched for “PCB drug,” you’re almost certainly looking for PCP, or phencyclidine, a powerful dissociative drug commonly known as angel dust. PCB refers to polychlorinated biphenyls, which are industrial chemicals, not a recreational substance. The two abbreviations get mixed up frequently, so let’s clear that up and cover what PCP actually is and does.
What PCP Is and How It Works
Phencyclidine, or PCP, is a synthetic drug that produces a trance-like state of detachment from reality. It was first discovered in 1926 and developed as a general anesthetic in the 1950s because it could block pain without significantly suppressing heart rate or breathing. Under the brand name Sernyl, it entered surgical use in 1963. By 1967, doctors stopped using it on humans because patients woke up with severe confusion, agitation, and hallucinations. After that, it was briefly limited to veterinary medicine before becoming a Schedule II controlled substance.
PCP works primarily by blocking a specific type of receptor in the brain responsible for learning, memory, and sensory processing. When that receptor is blocked, the normal flow of information between brain cells breaks down. The drug also mimics dopamine activity and affects several other chemical systems involved in mood, pain perception, and muscle coordination. This broad interference with brain signaling is what produces PCP’s wide and unpredictable range of effects.
Street Names and Forms
PCP goes by dozens of street names. The most common are angel dust, wet, embalming fluid, rocket fuel, love boat, and hog. When mixed with marijuana, it’s often called bionic, zoom, or wet. Mixed with cocaine, it may be called wack or space. The DEA’s reference list includes over 100 slang terms for PCP and its combinations.
The drug itself is a white crystalline powder that dissolves in water or alcohol. On the street, it’s sold as a powder, liquid, tablet, or capsule. It can be snorted, swallowed, smoked, or injected. One of the most common methods is dipping a cigarette or marijuana joint in liquid PCP and smoking it.
What PCP Feels Like and Does to the Body
The effects of PCP depend heavily on how much is taken, and the margin between a “mild” dose and a dangerous one is narrow. At low doses (roughly 1 to 5 milligrams), the drug causes sedation, loss of inhibition, slurred speech, and a blank, staring expression. Users often describe feeling disconnected from their body and surroundings, a state clinicians call dissociative anesthesia. Some people feel euphoric or disinhibited. Others become agitated or hostile.
Over half of people who show up in emergency departments after taking PCP present with the same cluster of signs: violent behavior, rapid heart rate, high blood pressure, numbness to pain, and a distinctive involuntary eye movement called nystagmus, where the eyes flick rapidly side to side, up and down, or in a rotary pattern. That eye movement is one of the most reliable physical giveaways of PCP intoxication.
At higher doses, PCP can cause seizures, dangerously high body temperature, muscle rigidity, and loss of consciousness. Because the drug numbs pain so effectively, people under its influence can injure themselves severely without realizing it, which partly explains PCP’s reputation for producing seemingly superhuman behavior.
Short-Term Effects vs. Long-Term Use
The immediate effects of a single dose typically peak within about an hour of ingestion, though the overall experience can last much longer depending on the amount taken and the method of use. PCP is detectable in urine for approximately 8 days after a single use, which reflects how slowly the body clears it.
Long-term or repeated PCP use carries more serious consequences. Chronic users can develop symptoms that closely resemble schizophrenia, including persistent hallucinations, paranoia, disordered thinking, and social withdrawal. These psychiatric effects can last weeks or months after the last dose. Memory problems, difficulty with speech, and depression are also common in heavy users.
Why PCP Is Considered Especially Dangerous
Several features make PCP riskier than many other street drugs. First, its effects are highly unpredictable. The same dose can produce calm detachment in one person and extreme aggression in another, or different reactions in the same person on different occasions. Second, because PCP blocks pain, users may not recognize injuries, burns, or other physical harm. Third, PCP’s stimulant properties can drive body temperature dangerously high, which in severe cases leads to organ damage.
The drug also interacts with so many brain systems simultaneously that its effects are difficult to manage in an emergency. It hits receptors involved in pain, mood, movement, inhibition, and consciousness all at once. This is fundamentally different from drugs that target a single pathway, and it’s part of why there is no specific antidote for PCP overdose. Emergency treatment focuses on managing individual symptoms like seizures, high blood pressure, and agitation.
PCB vs. PCP: The Confusion
PCBs, or polychlorinated biphenyls, are a completely different thing. They’re industrial chemicals that were widely used in electrical equipment, paints, and plastics before being banned in the late 1970s. PCBs persist in the environment and accumulate in fish and soil. Exposure to PCBs, especially during pregnancy and early childhood, has been linked to reduced IQ, altered behavior, thyroid disruption, reproductive problems, and increased risk of cardiovascular disease, liver disease, and diabetes. The EPA has set strict safety thresholds for PCB exposure in food and drinking water.
If you came across “PCB” in the context of drug use, drug testing, or substance abuse, the substance in question is PCP. The letters simply get transposed in casual conversation and internet searches.
