This depends on where you're located and the intentions behind it.
The United States hold 5% of the worlds population but consumes 75% of the worlds pharmaceuticals. I know quite a few people that are so dependent on these drugs that they don't even perceive an alternative.
I remember reading one study that stated that girls who play with dolls as a kid are more prone to have sex at a younger age as they felt the need to be loving and nurturing to the baby as a kid and think about it throughout their life more as they get older and want to act upon it. Can't say it has any correlation with the thought of teaching drug abuse in school although it is a thought.
Maybe ask someone in charge at your school like your principle and find out more as to why they don't have drug abuse as an education skill.
People are afraid to talk about these things because they are a hard topic to talk about. Some would prefer to just sweep it under the rug and chastise those with those issues. I wish it was a part of our education still because getting rid of the stigma of substance abuse is one of the ways that we can help our communities become stronger and closer.
