Substance use disorder, also known as substance abuse or addiction, is a chronic and progressive condition characterized by the inability to control one’s use of substances, such as drugs or alcohol.
It can have serious physical and psychological consequences, and can lead to significant impairments in an individual’s functioning.
People who have a family history of substance use disorders, or who have experienced trauma or stress, may be more at risk for developing an addiction.
Substance use disorders can also be influenced by social and cultural factors, such as the availability and acceptability of substances in one’s environment.
