Personally I don't see a thing wrong with it, and I teach my older kids about marijuana as far as my spiritual beliefs, and what marijuana prohibition is really about.. But one thing you always got to remember, the system is drilling it into our kids heads that marijuana is evil and will hurt anyone who uses it. Then they send police into the schools to talk to small children who don't know any better and telling them these things. There have been instances where the Police going to a classroom to give a anti drug presentation led to parents being arrested for marijuana related charges.
