1. Go to http://www.erowid.org/ it might be .com click on cannabis then there should be a drug test question. this site is awesome and will answer all your questions.
2. It depends on how much you have been smoking but you usually need to have smoked within 3-7 days for it to show positive.
3. i wish we didn't have to fear this, it is so stupid , the stuff is natural.
4. I don't know about saliva but it stays at least a month in your system. Usually they test your pee so a month of sobriety is a must.
5. Approximately 2-3 days depending on your size and weight. The smaller you are the better your chances. Even though a spray pf vinegar in the mouth a few minutes before the test will give a negative result. Trust me, I know from experience. Good Luck! Ray
