in my experience, not very.
i took one as a pre-employment requirement, after smoking heavily for 3 days during a going away party before i moved. i wasn't aware at the time that a test would be required so i was freaking out. the company did a swab test, and i passed! i quit, and a month later, went back to the same company. this time, i smoked a bowl on the way to the test.....and passed again.
i do smoke cigarettes, and from what I've gathered, brushing your teeth, mouthwash, smoking a cig, Chewing Gum, etc (essentially have anything in your mouth shortly before the test, in order to throw off the pH balance, will let you pass.) I've also known people that had serious amounts of xanax, hydrocodone, and oxycodone in their systems that passed as well.
The average mouth swab detects use for up to 48 hours.
Shouldn't be. A mouth swab test is testing DNA. Marijuana has nothing to do with your DNA, which cannot be changed.
No.
A swab test can detect marijuana in saliva for up to 24-48 hours after use. The detection window can vary depending on factors such as frequency of use and individual metabolism.
Not always.
Marijuana can typically be detected in a saliva swab test for up to 72 hours after use. However, individual factors such as metabolism and frequency of use can impact detection times.
no brush your teeth alot and gargle with mouthwash
Simple, it's a yes.
Wet with tongue not side of mouth
A swab test can typically detect marijuana use within the past 12-24 hours. The detection window may vary based on individual metabolism and frequency of use.
My probation officer told me 5-7 days after smoking.
its so easy to pass that test. just don't smoke three days before you take the test.
