Off the top of my head most RC's that could be active on a 1/4" x 1/4" hit have obvious differences (time to come up, total duration of trip, etc) when compared to lsd. It’s quite possible the blotter you refer to is something other that lsd, but it sounds like your friend wouldn't be able to positively id lsd anyway. Maybe the 3 hits of different white were weak lsd, some RC, or other substance, and this is the real deal potent lsd? Maybe the environment your friend was in at the time of the “hebephrenic like reactions” played a role in his/her behavior? No one is going to be able to tell you, from the info provided, what your friend took. I can tell you in the past 8 months or so there have been at least 4 distinct types of white on white unperfed blotter (definitely lsd) around that have ranged from fairly decent to surprisingly potent. With the state of things today it’s more important than ever to know and trust your source. The days of randomly dropping hits from a stranger are over, IMO, unless expecting 6-8 hrs and getting 14+ and heavy body load isn’t an issue.
