Drugs and Psychosis

– Psychosis can be induced by drugs or can be “drug assisted”. Some stimulating drugs, like amphetamines, can cause psychosis, while other drugs, including marijuana, can trigger the onset of psychosis in someone who is already at increased risk because they have “vulnerability”.

It is also believed that some drugs such as amphetamines and cocaine can cause a condition known as a drug-induced psychosis. This psychosis can last up to a few days, and is often characterized by hallucinations, delusions, memory loss and confusion. This usually results from prolonged or heavy street-drug use; and it responds well to treatment.
