A PCP (phencyclidine), also known as angel dust, is a dissociative drug that can alter a person’s perception, awareness, thoughts, emotions, and senses. A PCP trip refers to the altered state caused by the drug and may involve dissociation, distorted perception, confusion, hallucinations, paranoia, or changes in behavior.[1][3][5]
PCP was originally developed as an anesthetic, but its medical use was discontinued because of serious psychological effects, including agitation and hallucinations. Today, PCP is an illicit drug commonly associated with the street name angel dust. [1][4][5]
Unlike classic psychedelics that primarily intensify sensory experiences, PCP can produce dissociation, meaning a person may feel detached from their body or surroundings. It can also affect coordination, judgment, awareness, pain perception, mood, and behavior. [1][3][7]
A PCP trip is not necessarily pleasant or predictable. Some people may initially experience euphoria or a feeling of floating, while others may quickly develop anxiety, paranoia, confusion, hallucinations, or severe behavioral changes.[1][3][5]
What Does a PCP Trip Feel Like?
There is no single experience that describes every PCP trip. PCP can produce different effects depending on the person and circumstances. [1][3][4][5]
Someone experiencing a PCP trip may describe:
- Feeling detached from their body
- Feeling separated from their surroundings
- Distorted sights, sounds, or other perceptions
- A sense that time or space feels unusual
- Euphoria or unusual excitement
- Numbness or reduced sensitivity to pain
- Poor coordination or difficulty moving normally
- Slurred or garbled speech
- Confusion or difficulty thinking clearly
- Anxiety, fear, or paranoia
- Hallucinations
- Delusions or unusual beliefs
- A sense of unusual strength or invulnerability
- Agitation or unpredictable behavior
At higher levels of intoxication, the experience can become much more dangerous. Severe PCP intoxication may involve psychosis, extreme agitation, seizures, impaired consciousness, coma, or dangerously elevated body temperature.[1][4]
What Happens as a PCP Trip Wears Off?
As the acute effects subside, a person may continue to feel tired, confused, emotionally unsettled, or physically uncoordinated. The major effects may decline over several hours, but some psychological or physical effects can persist longer, particularly after severe intoxication. [1][2]
After a severe PCP reaction, healthcare professionals may evaluate the person for complications such as:
- Injuries
- Abnormal vital signs
- Hyperthermia
- Seizures
- Cardiovascular complications
- Other substances that may have been involved
- Persistent changes in mental status
Persistent hallucinations, severe confusion, paranoia, or major behavioral changes should not simply be assumed to be part of a normal comedown. They may require medical evaluation. [1][3]
If someone experiences repeated PCP-related episodes or has difficulty controlling their use, a substance-use assessment can help determine whether ongoing treatment or support may be appropriate. [3]
How Is PCP Used?
PCP can be used in several ways, including smoking, snorting, swallowing, or injecting. The effects and how quickly they begin can vary depending on the route of use and other individual factors.[1][4][5]
PCP may also be mixed with or applied to other substances, which can make the strength and effects difficult to predict.[1][3]
Because illicit PCP products can vary in concentration or contain other substances, a person cannot reliably predict how strongly they will be affected. This unpredictability can increase the risk of severe intoxication and other complications.[1][3]
How Long Does a PCP Trip Last?
A typical PCP trip or acute period of PCP intoxication lasts approximately 4 to 6 hours, although the duration can vary considerably depending on how PCP was taken, the amount involved, individual factors, and other substances used.[2]
The duration depends on factors such as:
- How PCP was taken
- The amount involved
- Individual metabolism and health
- Whether other substances were used
- The concentration or contents of an illicit product
- Whether the person has developed tolerance through repeated use
The major effects generally decline over several hours, but confusion, impaired coordination, unusual behavior, or other psychological effects can persist beyond the main period of intoxication. Severe reactions can last longer and may require medical treatment.
There is no dependable way to predict exactly when a particular PCP trip will end. If someone remains severely confused, agitated, unconscious, overheated, or otherwise medically unstable, do not assume they simply need more time for the drug to wear off.
How Does PCP Affect the Brain and Body?
PCP is a dissociative anesthetic and an NMDA receptor antagonist. It changes signaling in the brain and can alter perception, awareness, coordination, judgment, and behavior.[1]
Low to Moderate Intoxication
At lower to moderate levels of intoxication, PCP may cause dissociation, euphoria, altered perception, numbness, impaired coordination, slurred speech, increased heart rate, sweating, anxiety, or changes in judgment and awareness.[1][3][4]
A person may feel detached from their body or surroundings, experience distorted sights or sounds, or have a reduced sense of pain. Some people may also become confused, anxious, paranoid, or behave unpredictably.[1][3][4]
High Levels of Intoxication
Higher levels of PCP intoxication can produce more severe effects, including hallucinations, delusions, severe confusion, psychosis, extreme agitation, dangerously elevated body temperature, seizures, impaired consciousness, or coma.[1][4]
Severe intoxication can also cause rapid heart rate, high blood pressure, abnormal heart rhythms, and other cardiovascular complications.[1]
Long-Term Effects of PCP Use
Repeated or long-term PCP use can be associated with problems with memory, speech, thinking, mood, and weight. Some psychological or cognitive symptoms may continue after regular PCP use stops.[3]
Long-term or repeated use can also contribute to psychological dependence, cravings, and compulsive drug-seeking behavior.[3]
Physical Effects
PCP can cause physical effects such as:
- Numbness
- Poor coordination and balance
- Slurred or garbled speech
- Increased heart rate
- Elevated blood pressure
- Sweating
- Abnormal or involuntary eye movements
- Nausea and vomiting
- Reduced sensitivity to pain[1][4]
Severe PCP intoxication can progress to hyperthermia, abnormal heart rhythms, seizures, impaired consciousness, or coma.[1]
Why is a PCP Trip Unpredictable?
PCP does not affect everyone in the same way. The experience can vary according to the substance, route of exposure, amount involved, individual factors, and whether other substances were taken.
Illicit drugs may also contain unexpected substances or have unpredictable concentrations. This means a previous experience with PCP does not reliably predict what will happen during another episode. [7][1]
PCP can also produce unpredictable responses to external stimuli. A person may become confused, agitated, or behave dangerously without recognizing the risks around them.
This unpredictability is one reason a PCP trip should not be treated as simply a stronger version of an ordinary recreational drug experience.
When is a PCP Trip a Medical Emergency?
Some PCP reactions require immediate emergency medical care. [1][9]
Call 911 or your local emergency number if someone who may have taken PCP:
- Has a seizure
- Cannot be awakened or becomes unconscious
- Has trouble breathing
- Collapses
- Develops severe agitation, confusion, or psychosis
- Becomes dangerously overheated
- Develops severe or rapidly worsening symptoms
- Has signs of a serious cardiovascular problem
Severe PCP toxicity can involve hyperthermia, tachycardia, abnormal heart rhythms, severe hypertension, seizures, and coma.[1]
Warning Signs That Need Professional Evaluation
A PCP trip can sometimes cause severe symptoms that require urgent medical attention. Seek professional evaluation if someone develops hallucinations, paranoia, severe agitation, seizures, loss of consciousness, very high body temperature, or severe confusion.
- Hallucinations or paranoia: PCP can cause hallucinations, paranoia, and other changes in perception or thinking. Similar symptoms can also occur with other substances or medical and psychiatric conditions.
- Severe agitation: Extreme agitation can occur during severe intoxication and may also be a sign of delirium or another medical emergency.
- Seizure: A seizure requires emergency medical assessment, regardless of whether PCP is suspected.
- Loss of consciousness: Being unconscious or difficult to awaken can indicate serious intoxication or another dangerous medical condition.
- Very high body temperature: A markedly elevated body temperature can be a sign of severe toxicity and requires prompt medical evaluation.
- Severe confusion: Significant confusion or disorientation may indicate severe intoxication, delirium, or another underlying medical problem. [1][9]
Do not try to diagnose PCP intoxication based on symptoms alone. These signs can have many possible causes, and it may not be possible to determine what substance was taken without medical evaluation.
The immediate priorities are to keep the person safe and get appropriate medical help. If the person has a seizure, loses consciousness, has trouble breathing, or cannot be awakened, treat it as an emergency and call emergency services.
Can a PCP Trip Cause Psychosis?
Yes. PCP can cause hallucinations, paranoia, delusions, confusion, and psychotic symptoms. A PCP-related psychotic reaction can be difficult to distinguish from other causes of altered behavior without a professional evaluation.
Some psychological symptoms can also continue during the recovery period. Merck Manual notes that an emergence reaction during recovery from PCP can include bizarre behavior, psychosis, confusion, hallucinations, vivid dreams, or a sensation of floating, and some symptoms may persist for weeks.[1][3]
Persistent hallucinations, paranoia, severe confusion, or major behavioral changes should therefore be medically evaluated rather than assumed to be a normal part of the comedown.
Can Someone Become Addicted to PCP?
Yes. Repeated PCP use can lead to psychological dependence, cravings, and compulsive drug-seeking behavior.[3]
Long-term PCP use has been associated with problems involving memory, speech, thinking, mood, and weight. Some psychological or cognitive symptoms may continue after regular use stops.
A person may benefit from professional substance-use assessment if they:
- Keep using PCP despite harmful consequences
- Have difficulty stopping or reducing use
- Experience cravings
- Continue using despite physical or psychological problems
- Develop problems at school, work, home, or in relationships
- Need PCP to cope with daily life
A single PCP episode does not automatically mean that someone has a substance use disorder. The pattern of use and its effects on the person’s functioning are more important when determining whether ongoing treatment is appropriate.
Is PCP Illegal?
PCP (phencyclidine) is an illegal controlled substance in the United States. It is classified as a Schedule II controlled substance, meaning it has a high potential for misuse and dependence and is subject to strict federal controls.
PCP is not approved for routine medical use in the United States. Possessing, selling, manufacturing, or distributing PCP outside authorized circumstances can result in criminal penalties.
The legal consequences of PCP possession or distribution can vary by state and by the circumstances involved. If you have questions about the legal status of PCP in a particular state, consult an appropriate legal or government resource.
Can You Overdose on PCP?
Yes. A PCP overdose can cause severe and potentially life-threatening toxicity. The severity of an overdose can vary depending on the amount involved, how PCP was taken, individual factors, and whether other substances were also used. [1][3]
Severe PCP toxicity may cause:
- Severe confusion or delirium
- Extreme agitation or psychosis
- Very high body temperature (hyperthermia)
- Rapid heart rate or dangerously high blood pressure
- Abnormal heart rhythms
- Seizures
- Loss of consciousness
- Coma
- Serious injuries related to impaired judgment or coordination [1][3][4]
What To Do If Someone Overdoses on PCP?
A suspected PCP overdose should be treated as a medical emergency. Call 911 or your local emergency number immediately if the person has a seizure, collapses, cannot be awakened, has trouble breathing, becomes severely agitated or confused, or develops a dangerously high body temperature. [1][10]
Do not assume the person will simply sleep off the effects. Severe PCP intoxication can involve impaired consciousness and other potentially dangerous complications.
In the United States, Poison Control can also provide guidance for suspected poison exposure at 1-800-222-1222. However, call 911 immediately for life-threatening symptoms such as seizure, collapse, trouble breathing, or inability to awaken. [10]
What To Do If Someone Is Having a PCP Trip?
If someone is experiencing severe symptoms, seek emergency medical care immediately.
If the person is conscious and breathing normally but is confused, agitated, hallucinating, or behaving unusually, professional medical or poison-control guidance can help determine the appropriate next step.
If it is safe to do so:
- Stay with the person.
- Keep them away from traffic, heights, water, and other hazards.
- Avoid confrontation or unnecessary stimulation.
- Tell emergency responders what substance you believe was taken.
- Tell healthcare professionals if alcohol, medications, or other drugs may also have been involved.
- Provide packaging or other information about the substance if it is available.
Do not assume that a person is safe simply because they become quieter or appear to be sleeping. Severe intoxication can involve impaired consciousness and other medical complications.
How Is PCP Intoxication Treated?
There is no single medication that simply reverses a PCP trip. Treatment for acute PCP toxicity is primarily focused on keeping the person safe, monitoring their condition, and treating complications.
Medical teams may use supportive care and monitor vital signs. Depending on the symptoms, treatment may include medication to control severe agitation or seizures and additional interventions for cardiovascular or other complications. [1]
The appropriate treatment depends on the person’s symptoms and medical condition. Severe PCP intoxication should be managed in an appropriate medical setting rather than at home.
How Clearfork Academy Can Help
If PCP use is recurring or is affecting a teen’s mental health, behavior, relationships, school performance, or daily functioning, an adolescent-focused assessment can help determine what type of treatment and support may be appropriate.
Clearfork Academy provides behavioral health treatment for adolescents experiencing substance-use and related mental-health concerns. Its programs include residential treatment, Partial Hospitalization Programs (PHP), Intensive Outpatient Programs (IOP), and Virtual IOP care. The appropriate level of care depends on the teen’s clinical needs, safety, substance-use history, and need for structured support.
Clearfork Academy’s admissions team can also help families understand available levels of care and verify insurance benefits. Insurance coverage varies based on the plan, medical necessity, network status, authorization requirements, and level of care, so verification does not guarantee payment.
Note: PCP overdose or severe intoxication requires immediate medical attention. Clearfork Academy is a recovery and treatment option for ongoing substance-use concerns and is not a substitute for emergency medical care during an acute overdose.
