i'm worried about my friend. tonight i had to pick him up from a little get together. he was acting really weird. his eyes were kinda open more than usual and his face was twitching...especially his lips and around his mouth. he used to have a problem with drugs. i'm worried that hes getting back into them. does anyone know if any drugs have these effects? he wouldnt stop talking to me and thinking way to much into things. i asked him if he did any drugs, he promised me that he hadnt.

help
