Me, personally, not a huge fan. I dabbled and experimented like a good chunk of Americans, decided it wasn't for me. Not necessarily because I didn't enjoy it - although I was involved in quite a bit of team sports at the time and was worried about the health impacts - but because I saw the impact it was having on friends of mine.
YMMV (of course), but I simply saw too many ambitious, energetic people suddenly become very boring, and very comfortable with doing nothing. I have absolutely no doubt that it's a drug with tons of applications medicinally to treat everything from glaucoma to social anxiety to PTSD, but for purely recreational purposes, it appeared to be quite damaging and "Oh, alcohol is too!" just isn't a strong enough argument for me to be celebrating recreational legalization.
