I find this topic to be one of the hypocritical things about this scene. Its fairly obvious that whether you use or do not use, any permanent member of this community is tolerant. So if you choose to, I hope you do not feel judged by those who ask these types of questions, or do not use.
My own personal experiences: People post non stop on this board, and all the other "dead" boards and groups out there re: trips and weed and no one seems to blink an eye. I asked one question one time regarding seed mills, and I got hate mail for being a narc. Are you kidding me???
To the OP, I do not use, but I like to enjoy a few nice Ales in the lot before and during a show. And to me, there is no better smell than the lot of a show. That mix of weed, burritos, falafel, patchouli means home. If I could bottle that up I would.
