How can perceived norms influence a person s choices to use or not use drugs?

Perceived norms can influence a person's drug use choices by shaping their belief about how prevalent and accepted drug use is within their social environment. If a person believes that drug use is common and socially acceptable among their peers, they may be more likely to use drugs to conform to those perceived norms. On the other hand, if they believe that drug use is uncommon or frowned upon, they may be less likely to use drugs to avoid social disapproval and maintain their social identity.
