Steve M, Think back on your teenage years, and the teenagers now. Alcohol was not legal for them then or now, but it is for us. Did that keep you from taking a few drinks back then, is it keeping the teenagers from drinking now?? What if hard drugs were legalized, and accessible as alcohol is today. I hate to burst any bubbles, but many of the drugs that would be legalized are instantly addictive. Even to a moral and ethical child, the temptation to experiment comes along with an immature mind. Not to say that it would happen to all, just a lot, just like alcohol drinking.
I had access to drugs, through acquaintances and friends growing up, but I never did them, some of my friends did, and it was a long battle for them to get off them. If it was cheap and readily available, they would probably be dead.
To think your child is above the temptation is just not realistic. There will always be someone every now and again trying to temp them with things, and with it being legalized, it takes a lot of the ethical and moral stigmas associated with drugs away, and gives them a clear conscience to do drugs.
