TITLE: i think my best friend's other friends are bad influences on him. how do i tell him?
POST: my best friend and i have been best friends for 8 years and we are as close as brothers, he has been hanging out with this other group of guys for probably 5 years and they do drugs and drink to excess and stuff, my best friend and i like to party but they are dropping molly and acid and doing shrooms and coke and stuff, granted only on a once in a while basis but i think its bad and im worried he's going to get hooked. ive brought it up before that i dont like it and he just gets defensive and says he barely does it. i dont think he 's a drug addict but im worried it could lead to that. how do i address this with him?
TL;DR:
