What Is Angel Dust (PCP)?
What angel dust (PCP) is, its effects on the mind and body, why it is so dangerous and unpredictable, the risks of addiction, and how to get help.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Angel dust is a common street name for PCP (phencyclidine), a powerful and dangerous dissociative drug that alters perception, mood, and behaviour. Originally developed as an anaesthetic but abandoned for medical use because of its severe side effects, PCP is now used illicitly as a hallucinogen. It can be smoked, snorted, swallowed, or injected, and its effects include a sense of detachment from reality and one’s body, distorted perceptions, hallucinations, a feeling of invulnerability or numbness, and altered sense of time and space. Angel dust is especially dangerous because its effects are unpredictable and can include severe agitation, aggression, paranoia, and psychosis, sometimes with violent or self-destructive behaviour, as well as physical dangers such as high blood pressure, seizures, and, at high doses, coma and death. Because users may feel no pain and detached from reality, they can seriously injure themselves or others. PCP can also cause a psychosis that resembles schizophrenia, and long-term use can lead to lasting mental health and cognitive problems. It is addictive, causing cravings and compulsive use. If you or someone you know is using angel dust, it is dangerous, and help is available; PCP addiction is treatable with professional support.
What is angel dust?
Angel dust is a common street name for PCP (phencyclidine), a powerful and dangerous drug that profoundly alters perception, mood, thinking, and behaviour. PCP is classed as a dissociative drug, meaning it makes users feel detached or disconnected from reality, their surroundings, and their own bodies. It was originally developed in the mid-twentieth century as an anaesthetic for surgery, but it was abandoned for use in humans because of its severe and disturbing side effects, including agitation, delusions, and irrational behaviour. Since then it has been used illicitly as a recreational drug, valued by some users for its dissociative and hallucinogenic effects, but it is widely regarded as one of the more dangerous and unpredictable street drugs. Angel dust is just one of many street names for PCP.
This article explains what angel dust (PCP) is, its effects on the mind and body, why it is so dangerous and unpredictable, the risks of addiction, and how to get help. The central message is that PCP is a genuinely hazardous drug whose effects are erratic and can include severe agitation, aggression, paranoia, psychosis, and dangerous physical effects, and that it also carries a real risk of addiction and of lasting mental health harm. PCP can be found as a white powder, but also as a liquid or on other substances, and it can be smoked, snorted, swallowed, or injected. Understanding what angel dust is and does is important both for recognising its dangers and for knowing that, despite how serious it is, PCP addiction is treatable and help is available for anyone affected.
The effects of PCP on the mind and body
As a dissociative drug, PCP produces a sense of detachment from reality and from one’s own body. Users may feel disconnected, as though watching themselves from outside, and experience distorted perceptions of sight, sound, time, and space, along with hallucinations. Many describe a feeling of numbness, of not feeling pain, and sometimes a sense of great strength or invulnerability. The drug can produce euphoria in some, but its effects are highly variable and unpredictable, depending on the dose and the individual, and even the same person can have very different experiences on different occasions. This unpredictability is a large part of what makes PCP so dangerous.
The mental and behavioural effects can be severe and frightening. PCP can cause intense anxiety, paranoia, confusion, disorientation, agitation, and aggression, and it can trigger psychosis, a break from reality that can resemble schizophrenia, with delusions and hallucinations. Under its influence, and because they may feel no pain and be detached from reality, users can behave erratically, violently, or self-destructively, putting themselves and others at serious risk of harm. Physically, PCP can raise blood pressure and heart rate, cause a blank stare, rapid eye movements, loss of coordination and a staggering gait, slurred speech, drooling, nausea and vomiting, and sweating. At higher doses, it can cause dangerously high blood pressure, seizures, muscle rigidity, a dangerously high body temperature, and depressed breathing, and can lead to coma and death. Because the feeling of numbness and invulnerability removes the body’s normal warnings, users can suffer serious injuries without realising. These combined mental and physical effects make PCP intoxication a genuinely dangerous state.

Why angel dust is so dangerous
Angel dust is especially dangerous for several reasons. The first is unpredictability: PCP’s effects vary enormously with dose and individual, so a person cannot reliably know how they will react, and a dose that seems manageable one time can produce severe agitation, psychosis, or dangerous physical effects another time. The second is the behavioural danger: PCP can cause severe agitation, aggression, paranoia, and psychosis, sometimes leading to violent or self-destructive behaviour, and because users may feel no pain and be detached from reality, they can seriously injure themselves or others without realising, which has led to accidents, injuries, and deaths. Managing someone in this state can be extremely difficult and hazardous.
The third danger is the physical toxicity: at higher doses PCP can cause dangerously high blood pressure, seizures, dangerously high body temperature, muscle breakdown, depressed breathing, coma, and death, and combining it with alcohol or other depressants increases these risks. A fourth is the mental health harm: PCP can trigger a psychosis that resembles schizophrenia and may persist, and long-term use is associated with lasting mental health problems, cognitive difficulties, memory and thinking problems, and mood disturbances. There is also the risk that illicit PCP may be mixed with other substances or sold as, or contaminating, other drugs, adding further unpredictability. Together, these factors, the unpredictable and dangerous behaviour, the physical toxicity, the risk of lasting psychosis and cognitive harm, and the impurity of street supplies, make angel dust one of the more dangerous street drugs. Anyone using it, or around someone using it, should treat severe agitation, seizures, very high temperature, or unresponsiveness as a medical emergency.
Addiction and getting help
PCP is addictive. It can produce cravings and compulsive drug-seeking, and with regular use a person can develop tolerance (needing more for the same effect) and psychological dependence, using the drug compulsively despite the harm it causes. Stopping after regular use can produce withdrawal-type symptoms such as cravings, anxiety, depression, and difficulty with thinking and mood. Because PCP can cause such serious mental health and behavioural effects, addiction to it can be particularly damaging, entangling substance use with psychosis, cognitive problems, and dangerous behaviour. As with other substances, PCP is sometimes used to cope with underlying difficulties, and use can signal or worsen mental health problems.
The reassuring message is that PCP addiction is treatable, and help is available. Treatment generally centres on counselling and behavioural therapies, which help a person understand and change the patterns driving their use, manage cravings, and address any underlying issues, along with medical and psychiatric support, which is especially important given PCP’s potential to cause psychosis, agitation, and cognitive and mental health problems that may need treatment in their own right. For someone acutely intoxicated and agitated or psychotic, medical care in a safe environment is needed. For ongoing addiction, a structured treatment program, sometimes residential, can provide the support, safety, and therapy needed for recovery, and treatment also addresses any co-occurring mental health conditions. The key messages are that angel dust is a genuinely dangerous drug, that using it is hazardous to mind and body, and that if you or someone you know is using PCP or struggling with addiction to it, reaching out for professional help is important and can be life-changing, because with the right support people do recover.

If you or someone you know is using angel dust, it is dangerous, and help is available; PCP addiction is treatable with professional support.
As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “PCP, angel dust, is one of the drugs I most dread seeing, because it is so unpredictable. The same amount can leave one person spaced out and another in a violent, paranoid psychosis feeling no pain, which is how people get badly hurt, themselves and others. On top of that it can push blood pressure and temperature to dangerous levels, and it can leave lasting psychosis and thinking problems behind. It is also addictive. But it is treatable. We keep people safe through the acute state, treat any psychosis, and then do the real work with therapy. If someone is caught up in PCP, please get them help.”
Frequently asked questions
Is angel dust the same as PCP?
Yes. Angel dust is a common street name for PCP (phencyclidine). They are the same drug, a powerful dissociative substance that alters perception, mood, thinking, and behaviour and produces a sense of detachment from reality and one’s body. PCP has many other street names as well. It was originally developed as an anaesthetic but abandoned for human use because of its severe side effects, and it is now used illicitly. Angel dust/PCP can appear as a white powder, a liquid, or applied to other substances, and it can be smoked, snorted, swallowed, or injected. Whatever it is called, it is a dangerous and unpredictable drug that can cause severe agitation, psychosis, dangerous physical effects, and addiction. So if you hear the term angel dust, it refers to PCP, and the serious dangers described here apply.
What does PCP do to you?
PCP (angel dust) is a dissociative drug, so it makes users feel detached from reality, their surroundings, and their own bodies. Effects include distorted perceptions of sight, sound, time, and space, hallucinations, a sense of numbness or not feeling pain, and sometimes a feeling of great strength or invulnerability. Its effects are highly variable and unpredictable. Mentally and behaviourally, PCP can cause intense anxiety, paranoia, confusion, agitation, and aggression, and can trigger psychosis resembling schizophrenia. Physically, it can raise blood pressure and heart rate, cause a blank stare, rapid eye movements, loss of coordination, slurred speech, and nausea, and at higher doses cause seizures, dangerously high blood pressure and temperature, depressed breathing, coma, and death. Because users may feel no pain and be detached from reality, they can seriously injure themselves or others. These powerful and unpredictable effects are what make PCP so dangerous, and they are why it can be a medical emergency.
Why is angel dust so dangerous?
Angel dust (PCP) is so dangerous because of a combination of factors. First, its effects are highly unpredictable, varying with dose and individual, so a person cannot know how they will react. Second, it can cause severe agitation, aggression, paranoia, and psychosis, leading to violent or self-destructive behaviour, and because users may feel no pain and be detached from reality, they can seriously hurt themselves or others without realising. Third, it is physically toxic at higher doses, causing dangerously high blood pressure, seizures, high body temperature, depressed breathing, coma, and death, with the risks increased by combining it with alcohol or other depressants. Fourth, it can trigger lasting psychosis and is associated with long-term mental health and cognitive problems. And illicit PCP may be impure or mixed with other substances. Together these make PCP one of the more dangerous street drugs, and severe agitation, seizures, very high temperature, or unresponsiveness should be treated as a medical emergency.
Is PCP addictive?
Yes, PCP (angel dust) is addictive. It can produce cravings and compulsive drug-seeking, and with regular use a person can develop tolerance (needing more for the same effect) and psychological dependence, using it compulsively despite the harm. Stopping after regular use can cause withdrawal-type symptoms such as cravings, anxiety, depression, and difficulties with thinking and mood. Addiction to PCP can be particularly damaging because it entangles substance use with the drug’s serious effects, psychosis, cognitive problems, and dangerous behaviour, and PCP is sometimes used to cope with underlying difficulties, with use signalling or worsening mental health problems. The encouraging message is that PCP addiction is treatable, mainly through counselling and behavioural therapies, along with medical and psychiatric support, which is especially important given PCP’s potential to cause psychosis and cognitive and mental health effects. If your or someone else’s PCP use has become hard to control, seeking help is important, and recovery is possible.
Can PCP cause lasting mental health problems?
Yes, PCP can cause lasting mental health problems. Acutely, it can trigger a psychosis, a break from reality with delusions and hallucinations, that resembles schizophrenia, and this psychosis can sometimes persist beyond the immediate drug effects. Long-term or heavy use of PCP is associated with lasting mental health difficulties and cognitive problems, including problems with memory, thinking, and concentration, difficulties with speech, and mood disturbances such as depression and anxiety, some of which may persist even after stopping the drug. People with underlying vulnerability to mental illness may be at particular risk. This potential for lasting psychiatric and cognitive harm is one of the serious dangers of PCP and a reason its use is so concerning. It also means that treatment for PCP addiction often needs to address co-occurring or drug-induced mental health conditions in their own right. If someone is experiencing psychosis or ongoing mental health problems related to PCP use, professional psychiatric help is important, and treatment can help both the addiction and the mental health effects.
How is PCP addiction treated?
PCP addiction is treated mainly through counselling and behavioural therapies, which help a person understand and change the patterns driving their use, manage cravings, and address any underlying issues, combined with medical and psychiatric support. Psychiatric support is especially important with PCP because of its potential to cause psychosis, agitation, and cognitive and mental health problems that may need treatment in their own right. Someone acutely intoxicated, agitated, or psychotic needs medical care in a safe environment first. For ongoing addiction, a structured treatment program, sometimes residential, can provide the support, safety, and therapy needed for recovery, and treatment also addresses any co-occurring mental health conditions, which are common. There is no specific medication to reverse PCP addiction, so the focus is on therapy, support, and treating the associated mental and physical health effects. With this comprehensive approach, people do recover from PCP addiction. Given how dangerous the drug is, seeking professional help is important, and it can be life-changing.
