Understanding PCP Addiction

Learn About PCP Abuse & Addiction

PCP or phencyclidine is a crystalline synthetic illegal substance that offers anesthetic properties. PCP was originally developed as a surgical anesthetic under the name Sernyl in the 1950’s but was never used in medicine due to bizarre and seriously negative side effects that included agitation, delusions and irrational thinking.

PCP, a Schedule II controlled substance, produces its hallucinogenic effects as a NMDA receptor antagonist in the brain that blocks the activity of NMDA receptors in the brain and is significantly more dangerous than other categories of hallucinogens, such as ketamine (“Special K”), nitrous oxide (“whippets”), tileamine, and the cough-suppressant dextromethorphan. Used recreationally, the sedating effects of PCP, known on the streets as “angel dust,” “illy,” and “wet,” lead to a trance-like state during which people feel detached from their bodies and the environment around them. Many people who use PCP report feeling as if they are observing themselves from up above.

PCP may take the form of a tablet, capsule or colored powder. Most frequently sold on the streets as a powder or liquid it is abused by swallowing, snorting, smoking or injecting. The strong taste of PCP is masked by applying it to herbs such as the leaves of mint, oregano, parsley or tobacco. Sometimes PCP is applied to marijuana leaves to create a more potent effect.

Unfortunately, PCP is also a very addictive drug, which further increases the negative consequences associated with its use. Individuals who abuse PCP will develop a tolerance to the drug, and if they quit using, they may experience withdrawal symptoms. Once an addiction to PCP has developed, it can be extremely challenging to overcome without effective professional help.


Statistics for PCP Addiction

For individuals 12 and older the previous year prevalence rate was estimated at 0.10% while the lifetime prevalence rate was estimated at 2.5%.  However, there appears to be a significant age difference in use of this substance.

For adolescents ages 12-17 the estimated prevalence rate for the past year was 0.20% while the lifetime prevalence rate was estimated at 0.40%.  For young adults ages 18 to 25 the past month estimate was 0.2% while the lifetime estimate was 1%. Finally, for those ages 26 or older estimates for the past year prevalence rate was 0.00% while the lifetime estimate was estimated at 3.00%.

Causes & Risks

Causes & Risk Factors of PCP Addiction

Genetic: Those who have a first-degree relative who abuses drugs are more likely to abuse drugs than others without a similar family history. While there is only limited research related to hallucinogens, there is some support suggesting that those with a first-degree relative who used hallucinogens is at greater risk for abusing hallucinogens.

Brain Chemistry: PCP, like all drugs of addiction, affects the brain’s reward center.  Under normal circumstances the brain responds to situations that are pleasurable by releasing the dopamine, a neurotransmitter responsible for communication within the brain. PCP among other drugs, interferes with the communication process, causing the neurons in the brain to flood the brain with dopamine. The increased amount and length of dopamine flooding is what causes the high associated with taking PCP.

Brain Chemical Imbalances: Sometimes individuals have certain chemical imbalances with the brain. Some individuals have chemical imbalances that lead to lower levels of pleasure or increased negative mood states. When individuals come into contact with a substance that improves these states and creates pleasure it is very difficult to decide to return to the former state.

Environmental: While it is clear that there is a genetic predisposition to developing drug-related disorders including PCP abuse, this does not mean that everyone with the predisposition will develop such a disorder. Research shows that life stressors and other environmental influences account for about 50% of the risk that someone with such a predisposition will go on to develop the disorder.

An assessment is an important first step toward treatment of and recovery from addiction and co-occurring mental health issues.

I abused PCP for almost 2 years. I almost lost everything. In a last ditch effort to save myself, I asked for my family to help admit me to Acadiana's addiction program. They obliged and the rehab treatment was the first time in a long time that I could see clearly. I stayed the course, am now sober and stay active in their continuing care programs. Acadiana is a great facility and anyone considering getting help should take a serious look into their addiction program.
