I have a question and I read someone else had this same question awhile back. I'm having to take my drug test which I take Effexor / Venlafaxine at a high dose. I've been reading all over the internet how this shows up in a drug test as PCP!!! Can anyone help me out here? Either do you take this drug and what did it turn up as in your drug test? Or should I bring documentation about this showing up as PCP to my drug test.....or help me out on this situation. ...... please........Don't want PCP showing up on my drug test at all!
