I recently had a saliva drug test at lowe's and they sent the specimen out to a lab for testing. I smoked a little 60 hours before the test and it was the first time in a while. I have heard that THC is only in saliva for about 24 hours after smoking but because the specimen was sent to a lab I feel like it might be able to detect farther back. The test involved me putting a plastic stick with a square cotton end on my cheek for about 2 minutes. My mouth was kind of dry from the nervousness of just being interviewed. What do you think? Please...no "DONT DO DRUGS" campaigns and abstinence crap. I just want an honest answers from real people. Thank You. Kevinkusha: maybe you should learn to read before you go getting pissed off at someone who nicely asked you not to. I said SALIVA drug testing. I said nothing about SALVIA, the legal herb. I understand it is illegal, so is having fun in North Korea. I just want an answer. Thanks
