Phencyclidine (PCP) Addiction: Signs, Causes, Effects, Treatment, and Prevention

Phencyclidine, commonly known as PCP or angel dust, is a potent synthetic drug initially developed as a surgical anesthetic in the 1950s. However, due to its severe psychedelic effects and potential for abuse, its medical use was discontinued. Today, PCP is classified as a Schedule II controlled substance, notorious for its addictive properties when abused recreationally.

Phencyclidine (PCP) addiction manifests through various signs that indicate both physical and behavioral changes in individuals. These signs include hostile or aggressive behavior, isolation from loved ones, and neglect of work, school, or home responsibilities[. Physical symptoms such as numbness in limbs, impaired motor skills, and speech problems are also prevalent among PCP users.

The causes of PCP addiction are multifaceted, involving both chemical mechanisms and psychological/social factors. PCP disrupts neurotransmitter systems in the brain, affecting serotonin, norepinephrine, dopamine, and glutamate, which regulate mood, pleasure, and cognitive functions.

Psychological factors like underlying mental health issues (e.g., depression, anxiety) and genetic predisposition to substance abuse contribute significantly. Social influences such as peer pressure and exposure to environments where drug use is normalized also play a role in the development of addiction.

PCP addiction leads to a range of effects, both short-term and long-term. Short-term effects include intense hallucinations, detachment from reality, and erratic behavior.

Long-term consequences encompass persistent cognitive impairments, mental health disorders like anxiety and depression, and physical health issues such as liver damage and renal failure. The drug’s fat-soluble nature also leads to delayed effects, including recurrent hallucinations and prolonged psychological symptoms.

Treatment options for PCP addiction involve a comprehensive approach that includes medical detoxification, behavioral therapies like cognitive-behavioral therapy (CBT), support groups, and aftercare planning. Detox helps manage withdrawal symptoms, while therapies address the underlying psychological issues driving addiction. 

Preventing PCP addiction requires education about its dangers, early intervention in cases of mental health disorders, promoting healthy coping mechanisms, and fostering strong support networks within families and communities. By raising awareness and encouraging healthy lifestyles, you mitigate the risks associated with PCP addiction and support those in need of recovery.

What is Phencyclidine (PCP) Addiction?

Phencyclidine, commonly known as PCP or angel dust, is a powerful synthetic drug with a notorious reputation. Initially developed as a surgical anesthetic, PCP was discontinued for medical use due to its severe side effects. According to Bey T, Patel A. et al. 2007, “Phencyclidine intoxication and adverse effects: a clinical and pharmacological review of an illicit drug,” it is classified as a Schedule II controlled substance, recognized for its high potential for abuse and addiction. 

PCP was first synthesized in 1926 and introduced as a surgical anesthetic in the 1950s under the brand name Sernyl. However, its use in humans was discontinued in 1965 due to severe psychedelic side effects, including delusions and hallucinations, as mentioned by Schuckit, M.A. et al. 2000, “Phencyclidine (PCP). In: Drug and Alcohol Abuse.” By the 1960s, PCP emerged as a popular street drug, often manufactured in illicit laboratories.

What are the Signs and Symptoms of Phencyclidine (PCP) Addiction?

PCP has a range of behavioral, physical, and psychological symptoms that indicate abuse and dependence. Additionally, understanding the signs of overdose is vital for preventing potentially fatal consequences.

Behavioral Symptoms of PCP Addiction:

• Hostile or aggressive behavior. Over 50% of adult patients present with the classic toxidrome of PCP intoxication present hostile or aggressive behavior, according to Bey T, Patel A. et al. 2007, “Phencyclidine intoxication and adverse effects: a clinical and pharmacological review of an illicit drug.
• Isolation from family and friends
• Neglect of responsibilities at work, school, or home

• Numbness in arms and legs, leading to unintentional injuries. This loss of sensation is unsettling and dangerous, as it leads to unintentional injuries due to the inability to feel pain or other sensory inputs, as discussed by Brust JC. et al. 2014, “Neurologic complications of illicit drug abuse.”
• Impaired motor skills, causing clumsiness and difficulty walking
• Speech problems, including slurred or incoherent speech

Psychological Symptoms of PCP Addiction:

• Paranoia and hallucinations
• Mood swings
• Memory loss

What are the Signs of Overdose of Phencyclidine (PCP) Addiction?

The signs of overdose PCP addiction include agitation and hyperactivity, severe hallucinations or delusions, and a catatonic state.

Physical symptoms may include drooling, irregular heartbeat, seizures, and reduced blood pressure and body temperature.

Signs of PCP overdose include:

• Agitation and hyperactivity
• Severe hallucinations or delusions
• Catatonic state

Physical symptoms of PCP overdose include:

• Drooling: Excessive saliva production
• Irregular Heartbeat: Arrhythmias or palpitations
• Seizures: Convulsions requiring medical attention
• Reduced Blood Pressure and Body Temperature: Dangerously low levels risking shock or hypothermia

What are the Causes of Phencyclidine (PCP) Addiction?

The causes of Phencyclidine (PCP) Addiction include its profound effects on the brain’s neurotransmitter systems, the drug’s ability to create an intense sense of euphoria, and its hallucinogenic and dissociative effects. Additionally, individuals with underlying mental health issues are particularly vulnerable to PCP addiction. For more detailed information, please refer to the causes below:

• Chemical Mechanism: PCP inhibits the reuptake of serotonin, norepinephrine, and dopamine, creating an artificial sense of euphoria. PCP also blocks NMDA receptors, disrupting the action of glutamate, and leading to hallucinogenic and dissociative effects.

  These effects significantly increase the risk of addiction as users become reliant on the drug’s mind-altering experiences.

• Psychological and Social Factors: Individuals with underlying mental health issues, such as depression, anxiety, or trauma, turn to PCP for its mind-altering effects to escape their emotional pain or distress. Peer pressure, social acceptance, and exposure to drug-using environments increase the likelihood of PCP experimentation and subsequent addiction.

  Genetic predisposition to substance abuse also increases an individual’s susceptibility to addiction.

What are the Short-Term Effects of Phencyclidine (PCP) Addiction?

The short-term effects of PCP include intense hallucinations, feelings of detachment from reality, and significant changes in sensory perceptions. Users also experience agitation, euphoria, impaired motor skills, and unpredictable mood swings.

Immediate effects:

The effects of PCP vary based on the purity, method of ingestion, and dosage. Common short-term effects include:

• Sensory Distortions: Altered perception of body image, sight, sound, and time.
• Detachment: Dissociation from self and surroundings.
• Euphoria and Agitation: Intense euphoria followed by agitation.
• Physical Symptoms: Increased heart rate, shallow breathing, dizziness, and disorientation.

Dose-Dependent Effects

The dose-dependent effects of PCP addiction are: 

Dose Range	Effects

  • Motivational Interviewing (MI): Encourages motivation for positive change and recovery commitment.
  • Contingency Management (CM): Rewards sobriety and treatment participation.

• Medication: No specific medications treat PCP addiction. Certain drugs manage withdrawal symptoms and co-occurring mental health disorders.
• Support Groups: Support groups like Narcotics Anonymous (NA) offer ongoing support and encouragement from peers.

How to Prevent PCP Addiction?

Preventing PCP addiction involves education and awareness about the drug’s dangers, promoting healthy coping mechanisms for stress and mental health issues, and fostering strong family and community support systems. According to Carol A. Petsonk C A et al. 1979, “Angel Dust:” An Overview of Abuse Patterns and Prevention Strategies,” early intervention in cases of mental health issues and avoiding environments where drug use is prevalent also play significant roles in prevention.

• Education and Awareness: Raising awareness about PCP dangers and providing accurate information about its effects prevents initial use. Education programs target young people and at-risk populations.
• Early Intervention: Identifying early signs of PCP use and intervening before addiction progression proves crucial.

  This approach involves counseling, therapy, and support from family and friends.

• Healthy Lifestyle Choices: Encouraging healthy lifestyle choices and coping mechanisms reduces the likelihood of drug experimentation. Activities such as exercise, hobbies, and social engagement provide healthy alternatives to substance use.

How Long Does Pcp Stay in Your System?

PCP stays in your system for up to 7-14 days when detected in urine, but it can remain in your body for weeks or even months.

This is because PCP is stored in fatty tissues and released slowly over time.

Can Pcp Cause Permanent Brain Damage?

Yes, PCP can cause permanent brain damage. Chronic use of PCP leads to long-term cognitive impairments, including memory loss and difficulties with speech and thinking, potentially resulting in permanent brain damage.

Is There a Cure for Pcp Addiction?

While there is no “cure” for addiction, PCP addiction is effectively managed with a combination of medical detoxification, behavioral therapies, and ongoing support to maintain long-term sobriety.

What Are the Risks of Mixing Pcp with Other Drugs?

Mixing PCP with other drugs can be extremely dangerous. Combining PCP with other substances, especially depressants like alcohol or benzodiazepines, increases the risk of severe respiratory depression, coma, or death due to compounded effects on the central nervous system.

How Can I Help a Loved One Who Is Addicted to Pcp?

You can help a loved one who is addicted to PCP by encouraging them to seek professional treatment, offering support and understanding, and avoiding enabling their drug use. Educate yourself about PCP addiction and consider joining a support group for family members of those with substance use disorders.
