Despite a short-lived high, marijuana is the only drug that stays in the human body long enough to make urinalysis a deterrent. Marijuana's organic metabolites are fat-soluble and can linger for days. Synthetic drugs are water-soluble and exit the body quickly. An employee who uses methamphetamine on Friday night will likely test clean on Monday morning. If you think drug users don't know this, think again. Anyone capable of running a search on the Internet can find out how to thwart a drug test. Workplace drug tests may compel users of relatively harmless marijuana to switch to harder drugs to avoid testing positive. Drug-testing profiteers do not readily volunteer this information, for obvious reasons. The most commonly abused drug and the one most closely associated with violence is almost impossible to detect with urinalysis. That drug is alcohol, and it takes far more lives each year than all illegal drugs combined. Hangovers don't contribute to workplace safety, and counterproductive drug tests do absolutely nothing to discourage the No. 1 drug problem. ROBERT SHARPE Arlington, Va.
