Why did anyone ever think that rolling up dead leaves, setting them on fire and inhailing the carcinogens was a good idea? Yet how many millions of people have died from smoking? Your comment is a perfectly  rational and sensible comment coming from a rational and sensible person. The problem is that drug use is neither a sensible or rational behavior. Young people are taught from ECE drugs are bad. On the day after the overdoses in this village, how many villagers got high? In a way, the more you tell someone how dangerous a behavior is, the more they may feel challenged to try it to display defiance of authority. Guys might talk a girl into doing drugs so he can have sex with  her. Girls might do the drugs because they don't want to lose the guy.
