I think as long as it stays here (too many would object in the main forums and it would be a disaster) and is directed at safety it's a good thing. I am a Libertarian at heart (not a member of any political party) so to me what someone puts in their own body is up to them as long as no one else is harmed. However I will be the first to point out some potential long term consequences to others if asked.
In the 70's I became a member of NORMAL. I was a stoner till 93. Probably still would be if I hadn't got the paranoia. For those that don't know the paranoia isn't being afraid of getting caught, it's bad (as in violent) anxiety attacks with no idea what you are paranoid about. Had to stop cold turkey and tried it again a year later with the same results. Abstinence since then.
I had an eidetic memory which faded and losses in short term during that time period. Nothing directly links this to my choices but I'm not the only one to report these experiences, so who knows for sure.
Anyway, just my
