A major concern about drug testing is the fact that 65 prescription and over the counter medications produce false positive results. If someone takes Advil, Nuprin, Motrin, Excedrin IB (Ibuprofen), Aleve (Naproxen) , has a Kidney infection, Diabetes or Liver Disease there could be a false positive for marijuana. Nyquil, Contact, Sudafed, Allerest, Tavist-D, Dimetapp, Phenegan-D, Robitussin Cold and Flu, Vicks Nyquil (Ephedrine, pseudoephedrine, propylephedrine, phenylephrine, or desoxyephedrine) create erroneous indications for amphetamines. Poppy Seeds, Tylenol with codeine, Cough suppressants with Dextromethorphan (DXM), and most prescription pain medications produce a false positive for Heroin use.

Random drug testing has not been proven to deter drug use. In 2003, the National Institute on Drug Abuse funded the largest study ever conducted on the topic. Researchers found no differences in illegal drug use among students in schools that tested and those that did not.

Incidentally, using a $4 drug test is about as effective as using a peashooter to hunt elephants, the false positive rate will be enormous. But what do the Board of Trustees care about how many kids they wreck so long as they can posture as drug crusaders. A few expensive law suits because of false positives will give Amador County Trustees some new financial problems to wrestle with.

While they held office, Peter Bensinger (former DEA head), Robert L Dupont (former drug czar) and Carlton Turner (former drug czar) shamelessly promoted drug testing as the solution to drug problems. Later, they joined together to form Bensinger, Dupont & Associates, the world's largest drug testing company, to cash in the drug testing laws they wrote. Bensinger, Dupont & Associates reaps a fortune for their useless drug testing schemes.

The only beneficiaries of drug testing are the makers of the tests.
