The prevalence of psychosis caused by drug use varies depending on the kind of drug being used, as well as the individual’s history of substance abuse and mental health. Generally, psychosis is more likely to occur when a person has a history of drug misuse, is taking multiple substances, or is using drugs in combination with mental illness.
The most common underlying cause of drug-induced psychosis is the use of stimulants, such as cocaine and amphetamines. These drugs can cause the user to experience paranoia, delusions, and hallucinations. In some cases, the user may also become violent and aggressive. Studies have estimated that up to one-third of people who use stimulants will experience some form of psychosis.
Hallucinogens, such as LSD and psilocybin, are also associated with psychosis. These drugs can cause users to experience profound distortions in their perception and reality. Studies have found that up to 10 percent of people who use hallucinogens will experience some form of psychosis.
The use of marijuana has also been linked to psychosis. While the exact prevalence of marijuana-induced psychosis is unclear, studies suggest that up to 9 percent of people who use marijuana may experience psychosis.
In addition, prescription drugs, such as antidepressants and antipsychotics, can also cause psychosis. The exact prevalence of this type of psychosis is not known, but studies suggest that it is relatively rare.
Overall, the prevalence of drug-induced psychosis can vary depending on which drug is being used and the individual’s history of substance abuse and mental health. However, it is important to note that drug-induced psychosis is a serious condition and should be treated as soon as possible.
