interesting in light of the very first post, in which LJ says he thinks more people have tried it than not; and that CellarDwellars are a bunch of nerds.
I think it depends somewhat on your age, your circle of friends, your interests, your location, etc. When I was a teenager, certainly no one with any claims to coolness ever refused pot. It was ubiquitous.
The whole point (back then) was not just to get loaded; it was to expand your conciousness; to think in ways your parents didn't; to enhance creativity and attempt to reach Nirvana by chemical means; and to have fun, of course.
Things have changed.
