Having been required to submit to random urinalysis after a misdemeanor charge for possesion of cannabis, I tested positive for PCP on a five panel drug screen test. To say that I was fearful of the outcome would be an understatement. After much anxiety and contacting the manufacturer, it turns out that the test results occured because of an anti-depressent named Effexor.
While I am able to rectify this situation with my P.O., there may be others not so fortunate, as well as people being screened for employment related matters. I strongly suggest that you make this information widely available and inform web sites that offer information on drug testing about this problem.
