Key Takeaways

Phencyclidine (PCP) is a synthetic dissociative hallucinogenic. It causes sensory perception distortions, hallucinations, unusual sights, sounds, and colors.

People use this as a recreational drug despite it being illegal. It’s essential to understand the risks of using it and seek help if you or someone you know is struggling with addiction.

Is PCP Addictive?

Although certain hallucinogens aren’t typically addictive, PCP is. It’s a Schedule II controlled substance, meaning it has a high potential for abuse and can lead to physical and psychological dependence.

Regular use can lead to PCP use disorder that involves intense cravings and physical dependence. PCP addiction can lead to long-term health problems and even death.

When a person is addicted to the drug, they may spend significant time and money to obtain and use it. Dependence can also cause behavioral changes, such as using larger amounts of the drug more frequently than intended.

How Can You Prevent PCP Addiction?

To help prevent PCP addiction, it’s essential to follow these steps:

  • Avoid drug use: The best way to prevent addiction is to avoid using drugs, including PCP. This also includes limiting exposure to people who abuse it.
  • Educate yourself and others: Share information about the dangers of PCP use, its potential for addiction, and ways to seek help with friends and family members.
  • Seek alternative forms of recreation: If you or someone you know is using the substance as a form of recreation, try to find alternative activities that are enjoyable and don’t involve drug use.
  • Seek help for mental health conditions: Many people turn to drugs as a way to self-medicate underlying mental health conditions. If you or someone you know is struggling with mental health issues, seek proper treatment and support.
