Teaching How to Cheat on Test

Testing for recreational drugs has caused such a national stir that school officials are initiating programs with caution.

So far, the courts have stopped attempts by schools to implement on-campus mandatory programs.

In San Diego, W. Evan Sloane, managing director of a small group calling itself Question Authority, is challenging drug testing, but not through the legal system.

Sloane is running a service offering information about methods of doctoring urine samples to hide evidence of drug use.

For a $2 fee, callers can receive advice that includes drinking large quantities of fluid to dilute evidence of drugs in the urine sample, adding bleach or rubbing alcohol to samples to confound chemical tests and never donating the first urination of the day because of its high concentration level.

The service, which toxicologists say is largely accurate, also provides callers with information on the lengths of time that commonly used street drugs stay in the body. Most of the popular drugs the high school programs test for remain in the system from one to three days. Marijuana can be detected up to 45 days. Alcohol is excreted within 10 hours.
