Although your teen may tell you "everybody's doing it," don't view teens or adults smoking pot (marijuana) as "normal" or a "rite of passage". When teens are using pot while suffering from depression, there are associated increased suicidal thoughts, plans, or attempts. You haven't lost your legitimate authority as a parent if you used pot in the past. What you as a parent believe is right, right now, is what matters. The alternative is accepting risk and hope for the best. According to the Substance Abuse Mental Health Administration (SAMHSA), 20% of parents don't believe they have any influence over their teen's decision about drug abuse. Their study shows teens think just the opposite. What a parent says does matter. Collect facts and use them to beef up your parenting resolve to prevent drug abuse.
