Drug Test False Positive Results

Drug Testing Results

According to a news report from the Los Angeles Times New Service, a study of 161 prescription and over the counter medications showed that 65 of them produced false positive drug test results in the most widely administered urine drug test procedure. Ronald Siegel, a psychopharmacologist at UCLA said 'The widespread testing and reliance on tell-tale traces of drugs in the urine is simply a panic reaction invoked because the normal techniques for controlling drug use haven't worked very well. The next epidemic will be testing abuse." Currently there are more than 250 over-the-counter medications and prescription drugs that can cause false positives.
