MXE is just a shitty version of ketamine thats impossible to hole on... I seriously don't understand what the hype is all about. I just flushed a gram down the toilet.LSD is the best drug there is hands down.GHB and ketamine are also some favorites that have little or no negative effects unless you seriously overuse them.Addictive stims and opis are just asking for trouble. Looks like you have narrowed your options being that you don't like hallucinogens or downers... There isn't much else other than stims when you put it that way. I would seriously give LSD a shot if I were you though.
