In social groups where drug use is common, individual group members who repeatedly use drugs may increase the salience of drug-related cues (i.e., they draw attention to drug-related cues and increase the stimulus control exerted by those cues) for other group members, thereby contributing to further drug use and an increased likelihood of relapse in vulnerable individuals.

Some researchers believe that substance use disorders are a biological phenomenon. The biological theory of substance use helps us understand how substances impact our brain and the changes that happen. Please watch the following short video on how substances impact the brain. If you think about any activity you participate in, if it makes you feel...
Using psychology also helps us understand substance use disorders. There are a variety of psychological approaches that help us understand behaviours, treatment, and recovery.
