After all, a scientist like Dobie just sees a sample in a test tube. There’s no test to match the piss to the pisser. “If you can just tape some kind of test tube with a friend’s urine in it to your thigh so it’s about as warm as your natural body temp, then you’re going to pass,” Dobie says. However, it’s not the easiest thing to pull off. Some tests are preceded by a pat-down and others are literally observed (read: someone watches you pee) by the test administrator. Many samples are immediately checked for temperature. There are products available to deceive monitors in the case of an observed test (read: a fake penis that dispenses a clean urine sample) and they’re available online.
Legal weed doesn’t necessarily guarantee an unfettered cannabis experience. Employees are still regularly subjected to mouth swab drug test screenings. And police in recreational-use states are trying to figure out how to deal with an alleged increase in drivers under the influence of cannabis. In short, with more people smoking weed, more people are interested in testing for it, especially on the job and behind the wheel. And unlike blood or urine tests, mouth swab drug tests are cheap and fast, which means knowing how to pass a mouth swab drug test is more important than ever.
