When it comes to alcohol and other drugs, the "Just Say No" approach is probably too simplistic. By the time they reach older adolescence, many teens have been exposed to alcohol and drugs and may have seen classmates or friends experiment without negative consequences.
Scare tactics are unlikely to work and are more likely to elicit looks of boredom and disbelief. Instead, your soon-to-be college student needs thoughtful communication, education about the facts, reasoned discussion of expectations, and strategies for making wise choices.
Although teens sometimes seems to have one foot out the door, parents STILL MATTER (http://www.theantidrug.com/ei/) and you can help your teen make decisions not to drink, smoke, or use other drugs. Nobody said parenting was easy. The more independent your teen gets the more you may feel yourself caught between wanting to hold on and getting ready to let go.
Even though it may feel like he or she is almost an adult, your college-bound teen still looks to you for guidance and support. Stay involved, because your influence and advice makes a difference!
