yeah I wouldn't really trust anyone in that type of circle. The adage "you can't rely on anyone except yourself" has added meaning in the drug culture. People don't seem to be as stable. They'll either totally tweak out and become unbearable or they will want to leave the party scene entirely by cutting off friends therein, which sucks for moderate people like you that just want to be chill and have fun. Just be comfortable with yourself and look for happiness inside yourself
