Someone gave my friend a Xanax capsule and he took it. though I don't think they make xanex in capsules. It was a cream capsule with white powder inside. Any ideas what it could've been?
Not sure off hand, but you can check an online pill id site, eg rxlist.com.
This is not a good basis for an FAQ, so I'm going to go ahead and close the thread; please pay attention to which subforum you're posting in next time.
