If I have been a moderate smoker and haven't smoked for 45 days... what is the likelihood I will still get a positive UA test? Also based on your experience if they are doing an EtG test for alcohol are they also checking for mairjuana? The test only cost me $8... what can they possibly check for $8? Lab costs have to be expensive or is it just a matter of a test strip for pot? What do you think?
