Party Vibe

This is going to be my first post here and its going to be a question, has anyone taken e and not receive a trip at all? My drug of choice will always be weed but lately ive been trying/wanting to try crazier drugs but i wont be trying any of the highly addictive drugs but im more enticed by hallucinogens. so far ive taken e on 2 occasions both giving me very mild highs my friends said they got hold of some that made them trip out bad but the times i did it with them no one expierenced anything other than a bit of hyperness :bounce_fl and big ass pupils is there a way to distinct the strong e and the weak e?
