medication that can cause psychosis
For example, taking a large amount of cocaine all at once can cause psychosis in minutes. Psychosis from cocaine or amphetamine use typically produces persecutory delusions. Hallucinogens can, of course, cause visual, auditory, and tactile hallucinations, but this is not the same as psychosis. However, an adverse reaction or taking too much of this kind of drug can also cause delusions and paranoia.
