1. three months i think
2. 19 days, 6 hours, 49 mins and 2 seconds. After that, you are in the clear! Good luck with it.
3. Here ya go... "Saliva drug testing cannot be used as a comprehensive drug test for detecting long term drug use patterns. Most drugs do not leave a residue in the saliva beyond a 20 hour period. Saliva drug testing can be used safely to judge whether the person has consumed drugs within the last 24 hours but it won’t detect if the person has any history of drug abuse at all. A hair drug test would beat saliva drug testing at it any given day going back up to 90 days, but a hair drug test takes a month or so to give results." http://ezinearticles.com/?Researches-on-Saliva-Drug-Testing&id=737711 Though if you are smart, you would stop the drug use instead of putting your job, health, life, at risk.
4. Depending upon use and body wieght, I would say that 30 days will do it safely.
5. The Oral Fluid Drug Test detection time Cocaine (COC) up to 24 hours Amphetamine (AMP) up to 72 hours Methamphetamine (mAMP) up to 72 hours Opiates (OPI) 24-48 hours Marijuana (THC) up to 14 hours
