Before I tried grass in college, which was 25 years ago for me, I bought into all the anti-drug education I'd gotten coming up through school in the 70s.

That was before the days of Nancy Reagan's Just Say No campaign, but I grew up in a university town, and so as early as the late 60s, when I was a little kid and when drugs were so popular in college hippie culture, we were getting drugs-are-dangerous education through our elementary schools.

You don't really have a way to believe anything else other than the drugs-are-bad message when that's what you're routinely taught as a kid.
