How to Recognize Substance-Induced Psychosis

When someone takes drugs, they may experience drug-induced psychosis (DIP).

Substances such as PCP, GHB, MDMA, LSD, alcohol, opioids, benzodiazepines, stimulants like cocaine and methamphetamine, and even caffeine and nicotine have been linked to psychosis, depending on individual sensitivity and dosage.

DIPs may occur with first time users who take too much of their drug of choice or any amount in between. Often times, people do not know that they’re experiencing a DIP. It occurs when drug use causes psychotic symptoms such as:

  • Fear
  • Anxiety
  • Paranoia
  • Depression and suicidal thoughts or actions

The drug that causes the psychotic effects varies widely depending on the drug. For example, GHB can cause GHB-induced psychosis, while methamphetamine can cause methamphetamine-induced psychoses.

What are the Risk Factors for Drug-induced Psychosis?
