Methamphetamine and psychosis: risk and vulnerability factors

Psychotic symptoms are common in people who use the drug methamphetamine (ice), but the risk factors for this are unclear. This thesis involved six studies that consolidated recent evidence, and also collected data from adults who use methamphetamine, and people without drug use. Methamphetamine was found to be a key driver of psychotic symptoms, but this work also led to new findings relating to differences in how people with methamphetamine psychosis perceive emotions in others, in comparison to both people who use methamphetamine and don’t have psychotic symptoms, and compared to people without drug use.
