Substance Use Disorder

Addiction is a complex brain disease that is manifested by compulsive substance use despite harmful consequence. People with addiction (severe substance use disorder) have an intense focus on using a certain substance(s), such as alcohol or drugs, to the point that it impacts their entire life. Addiction can be a life threatening condition depending on what the individual is addicted to.

It is widely believed that addiction includes obsessive thoughts about the substance, or process (e.g., gaming), and it takes a priority in the individuals life. People can become dependent on psychoactive chemicals (e.g., alcohol and other drugs), gambling, gaming, sex and masturbation, spending money, work, food, exercise – however, the main criterion for addiciton is that the behaviour is causing harm to the individual and they cannot stop when attempting to control, reduce or cease the behaviour.
