There is a complex relationship between mental health and alcohol and other drug use. A mental illness may make a person more likely to use drugs to provide short-term relief from their symptoms, while other people have drug problems that may trigger the first symptoms of mental illness (AIHW 2020). Stimulant drugs can make you feel depressed, anxious and paranoid. Cocaine – a type of stimulant – can make previous mental health problems recur and trigger psychosis and schizophrenia. Ecstasy users can experience memory problems. Hallucinogenic drugs such as magic mushrooms can make any mental health issues worse.
