Is there any way to cheat an oral fluid saliva test?

I guess not, because I googled to no avail, but I have to try. I don't mean the tests where you put a stick in the mouth and move it around a little - but those where you take a solution in your mouth for 2 min and spit it out

Anything I can prep my mouth with to make it fail?


best regards

Bluelight does not allow drug testing discussion so I'm closing this.
