If you think you are being unjustly tested, you may have cause for legal action. We are sorry having to mention these devious techniques, but feel it is necessary to defend innocent people against wrongful accusations of drug abuse. Drug testing aids are available at many head and hemp shops. Many drug abuse clinics offer urine testing for a fee. Home test kits are available from companies such as Liberty Research and Instant Diagnostics.
Urine tests intrude on intimate bodily privacy.
Mass drug screening violates the privacy of the majority of responsible employees in order to spot a minority of alleged drug abusers, many of whom are in fact not drug abusers at all. However, the 4th Amendment does not generally apply to tests by private employers. No test is infallible. Surveys of drug testing labs have found remarkably high error rates from poor quality control. Because drug tests are highly sensitive to marijuana, random testing can promote use of other, more dangerous drugs such as cocaine and opiates, which wash out in 2-3 days, or LSD, which is rarely tested.
