I'm not a pot smoker. I got into this because urine testing is un-American. Testers invade your person on the presumption of guilt until innocence is proven, which violates the 5th amendment. Urine tests don't enhance the public's safety because they measure what happened at the party last weekend rather than a person's current performance capacity. The basic emit test is triggered by more than 250 over the counter medications.
False positives run high.
Our prison system is filled with minor marijuana offenders which costs the tax payers a fortune. In the past, various drinks such as Test Free, worked because they diluted a sample under the threshold of the test. Water, Ice tea,or Pepsi work as well. Dillution alone will be increasingly risky under the new cut off levels. Visine does not work.
