I got given some of this recently and was at work so thought id have a small one up the nose first (had I think 3 small ones and one big fucker) gave a mate one to take home . felt nothing so thought id have the big fucker under my tongue....still nothing. so thought fuck it put the last one up my nose. nothing for a while, till I was driving and had that nice trip you get from similar effects to 2ce but I was functioning fine. had a 2ce sort of trip for about 30 or so min then came down. did I obviously do something wrong here? or could weather of damaged them (were in a dark place but not fridged)
