Substance Use Disorder

Book Appointment

Substance use disorder is a health condition in which a person has difficulty controlling their use of a substance despite its harmful effects on their health, relationships, work, education, or daily life. It can involve alcohol, tobacco, illegal drugs, or prescription medicines used in ways other than directed. 

Repeated substance use can affect brain function, cravings, and behaviour, making it difficult to stop using a substance without support. 

Substance use disorder is a treatable medical condition, not a moral failing or a lack of willpower. With appropriate treatment and support, recovery is possible.
