I recall those days. My mother HATED D&D, and didn't want me involved... my dad overruled her, would even sometimes take me to buy books, figuring that D&D was better than me hanging out and getting high with my friends.
I have never touched an illicit drug in my life.
I recall that it took a long time for my wife to be accepting of D&D... she'd been fed these lies, and had a very negative impression.
