Ok heres the thing, I smoked about half a blunt last Friday night at around 730pm. Ive smoked before but the last time I smoked was New Years Eve so its been almost a year since ive smoked as I am not a frequent smoker. I have a drug test comming up this Friday...any tips to help me pass this drug test? Its a urine test and im aware that THC can stay in your system for up to 30 days depending on the frequency of marijuana use. Again, I smoke maybe once or twice a year...havent smoked since december of last year, i smoked last friday and taking a urine test this friday....any tips of things i can do pass this urine test?
