How many days back does the swab drug test detect THC?

People say that if you just brush your teeth good enough or drink pickle juice you will be fine. That is a bunch of BS. swab tests go back about a month or so (give or take a week or two depending on your metabolism). Idk if it's true that they sometimes fail, but would you really take that risk? There are pills that claim to cleanse your system in days but it's all a scam. Just quit for 2 months and you can be sure.

I don't know about your answer because not even a week ago I had to take a swab test for a job and I smoked marijuana that day not knowing i was going to get tested and I passed and got the job, all I did was use listerine once not even thinking I was going to get tested and I passed, Im honestly still surprised but when they gave me the drug test i wasnt going to say no cuz then they realy wouldn't hire me
