you should dress up like a hooker and stand on a local street corner. looking like that around people you are familiar with should make you more comfortable around people you don't know [/sarcasm]
the xanax idea might be decent, and they are fairly easy to get. ask the person you get your smoke from and see if they can hook you up. small ones shouldnt cost more then a couple bucks a pill, less if you buy in quantity. for a while i could get them $.30 each but i had to buy a hell of a lot of them
