Signs of Substance Use Disorder

Substance use disorder is a broad term that includes substance misuse, dependence and addiction to alcohol, legal and/or illegal substances.

Signs of a substance use disorder may include behavioral, physical and social changes. There are a number of warning signs to look for when you suspect someone might be struggling with a substance use disorder.

Addiction, the most severe level of substance use disorder, is a chronic disease characterized by continuing a behavior despite the harm and unintended consequences it may cause. Addiction causes changes in the brain that over time interfere with a person’s self-control and ability to resist cravings.
