Quite an emotional feel. A blind test where workers are tested but the results were kept by the testers. They followed the people over several years and low and behold the puffers had a higher rate of employment advancement than non puffers. Problems with random drug testing. Why the tests don't work.
Drug tests are an attack on lifestyle choice under the guise of workplace performace.
Unlike alcohol tests which test for current inebriation, drug tests test for any presence of a drug as far back in history as the tests can go. Good employees are being ostracized, arrested, fired or forced into drug rehab for the mere presence of any illegal drug.
