i twitched and shit from weed last friday. no problem dude. i had some pain and shit. its just some highs are not very kind to u. theres really no way to tell from what u felt if it was laced. weed can react however it wants to. U smoke don't expect a high. expect to have weed push u wherever u want or don't want. u don't control what happens, no it does. it gives but it also fucks. sounds like a lot of caffeine may have helped with the whole twitching thing.
