I have searched all over the net for a list of drugs that cause false positives or negitives or that simply will disquality you from being a candidate for the test.

Can you direct me to a list of drugs preferably perscription medications that will disqualify someone from testing.

I am currently taking Atenolol (a beta blocker) which may, the only other medication was Miltown other than that I have found no additonal information.
