DOM etc... are pretty rare but I have seen a few uppity ups in the slinging biz that find the stuff sometimes. They always say it is mescaline. Fucking wankers think they are big shots. I would almost always suspect a micro dot or pill as containing LSD but some of these little buggers last a good 12-14 hours, hit in waves. etc etc... classic. Way too small to be mescaline, but definatly not acid.
