Drug Testing Does not Work!

Drug testing of any kind, including for cause or suspicion, is not a significant predictor of marijuana use or any other harmful drug usage detection known.

Companies which use Factor 1000, an impairment testing system, find that drug and alcohol use are not the most common reasons for accidents; rather, severe fatigue and illness are more common.

One reason drug testing is not used by some employers is the cost. One electronics manufacturer estimated that the cost of finding each positive result was $20,000. After testing 10,000 employees he only found 49 positive results. A congressional committee estimated that the cost of each positive in government testing was $77,000 because the positive rate was only 0.5%.

An Oklahoma study found that a questionnaire was able to accurately detect 94 out of 100 drug abusers. The questionnaire was also useful in detecting alcohol abusers, something drug tests fail to accomplish.

Most types of drug tests fail to detect alcohol abuse – the most commonly abused substance among Americans – and are most likely to detect marijuana use since the active ingredient in marijuana stays in the body’s system longer than any other illicit substance. Therefore, drug tests often fail to identify people who are using more powerful, more addictive and more dangerous drugs like methamphetamine or cocaine, which exit the body’s system in a matter of hours or days.
