If you're going to tell me to quit smoking pot, or that I'm ruining my life...Just click the back button now. Serious answers only, please :) Okay, So I have an interview for a job tomorrow and I know for a fact they do a saliva drug test as a condition of employment. I have a feeling that if I pass the interview, I'll be tested tomorrow. I've heard saliva drug tests can only detect marijuana for up to 24hrs. is this true? The last time I smoked was Friday around 2pm and I smoke regularly (1 or 2 bong bowls a day on avg.) So if the last time I smoked was Friday... my saliva should pass if I get tested tomorrow (Monday), right? I'm fairly confident that I'll pass, But it'd be nice to get some feedback from someone who has more experience on passing drug tests.
