Although experts are predicting drug testing won’t entirely disappear due to the increased legalization of marijuana, they have said that the scope and type of testing should change. A recent report by Quest Diagnostics revealed that the number of United States workers and job applicants testing positive for drugs hit a 14-year high, with marijuana in the lead. New York City has also approved a bill that would prohibit forcing job candidates to take marijuana screening tests. But research conducted by Michael Frone, author of “Alcohol and Illicit Drug Use in the Workforce and Workplace,” suggests that drug tests are unlikely to reduce future substance use. Urine tests, added Paul Armentano, deputy director of the National Organization for the Reform of Marijuana Laws, “do not indicate marijuana intoxication in current employees” since THC main remain in the body for days or weeks after the use of cannabis.
