INTRODUCTION
Disorders due to substance use are mental and behavioural disorders that develop as a result of the use of predominantly psychoactive substances, including medications.
There is a repeated drug use which leads to long-lasting changes in the brain that undermine voluntary control.
From a neurobiological perspective, substance use disorder is a disease of the brain and the associated abnormal behaviour is the result of dysfunction of the brain tissues.
