Hello.. new to the forums here.. I've read the instructions on passing a saliva test but what about if you have a random.. or in my case.. if something happens like an accident or mess something up i have to test and might not get the 24 or 48 hour window i would need. Is there a product that works 100 percent or close to it like a mouthwash of some sort? I'm not a real heavy user. I take 1 toke at night when i get off work and that's it. Thanks for all the support here it's great to see so many people provide there opinions and help each other out!
