PCP's Effects on Your Brain

PCP is a mind-altering drug. This means it acts on your brain (central nervous system) and changes your mood, behavior, and the way you relate to the world around you. Scientists think it blocks the normal actions of certain brain chemicals.

PCP is in a class of drugs called hallucinogens. These are substances that cause hallucinations. These are things that you see, hear, or feel while awake that appear to be real, but instead have been created by the mind.

PCP can be Addictive

People who use PCP can get psychologically addicted to it. This means their mind is dependent on PCP. They are not able to control their use of it and they need PCP to get through daily life.

Addiction can lead to tolerance. Tolerance means you need more and more PCP to get the same high. If you try to stop using, you may have reactions. These are called withdrawal symptoms, and may include:

Treatment Options

Treatment begins with recognizing there is a problem. Once you decide you want to do something about your PCP use, the next step is to get help and support.

Treatment programs use behavior change techniques through counseling (talk therapy). The aim is to help you understand your behaviors and why you use PCP. Involving family and friends during counseling can help support you and keep you from going back to using (relapsing).

If you have severe withdrawal symptoms, you may need to stay at a live-in treatment program. There, your health and safety can be monitored as you recover. Medicines may be used to treat withdrawal symptoms.

At this time, there is no medicine that can help reduce the use of PCP by blocking its effects. But, scientists are researching such medicines.

Your Ongoing Recovery

Resources

Resources that may help you on your road to recovery include:

When to Call the Doctor

Call for an appointment with your health care provider if you or someone you know is addicted to PCP and needs help stopping. Also call if you are having withdrawal symptoms that concern you.
