I think a good way to prevent kids from using drugs in school or outa school would be to let them know what they do to you and others around you. when i was in elementary i had the D.A.R.E program and it was good and learned a lot from it. some kids thought it was dumb but i thought it was an effective way for kids to learn and know bout drugs and how they work and will mess your life up even your schooling. Maybge if you offered kids a reward for being drug free they would try harder and help others like their friends and people around them. well its a way to start. also if they had more programs set up that taught you bout drugs and everything. Another effective way to prevent kids from doing drugs would be to make more sever punishments for those students who get caught with drugs and alcohol. This would set an example for others in the school and hopefully keep drugs out of the school, and away from the students. and even if the parnets would help out and talk to their kids and others keep eyes on them.
