As many as two-thirds of Meth users can experience some form of psychosis, which can begin within the first few months of use. They can become consumed by paranoia and fear—believing they are in constant danger and people are out to get them. This delusional state of mind is very similar to that of paranoid schizophrenia.



  • An idea or thought that a person believes in completely, even if there is no evidence to support it or it has been proven false. Methamphetamine distorts a user’s ability to tell what is real and what is not. Delusions caused by Meth can include feelings of paranoia or of being in constant danger. Ryan's Story

  • Seeing, hearing, or feeling things that do not exist. Since methamphetamine makes users paranoid, the hallucinations tend to be sinister or threatening. These false perceptions may include seeing what Meth users refer to as “shadow people” or imagining that insects are under their skin. Alan's Story

  • A state in which people have irrational fears and delusions of being in constant danger and that other people want to harm them. Meth causes this disorder by overstimulating emotional regions of the brain and compromising areas that control judgment. The Anxious Mind
