F19: Mental and behavioural disorders due to multiple drug use and use of other psychoactive substances

Mental and behavioural disorders due to multiple drug use and use of other psychoactive substances encompass a broad range of conditions. These disorders occur when an individual regularly uses multiple drugs or other mind-altering substances to the extent where it negatively impacts their mental and behavioral health. This group of disorders typically presents through altered thought processes, mood swings, erratic or unpredictable behavior, cognitive impairment, and impaired social functioning. Progression of these disorders often leads to addiction, and symptoms intensify the longer substance use continues without intervention. All major body systems can be affected, as substance use also results in physical health diseases. The condition is not transmitted from person to person, but research suggests genetic and environmental factors influence susceptibility. It's important to note that consistent use of multiple drugs and psychoactive substances typically leads to these disorders.
