here's what you do....make sure it's yoru shit..when they start acting stupid tell them they are cut off...meaning they can't have no more til they're sober or know how to deal with the high responsibly and not be an idiot....worked with alot of my friends.....they can either act stupid or they can smoke....cuz with tme stupid ppl is a buzzkill....and THERE IS A MAJOR DIFFRENCE Between a stuipd person and someone who acts stupid to make high ppl laugh...
