Well I wanna test to see that I'm clean of any pot in my system. I stopped smoking around the 28-29 or feb then smoked a very small bowl 4 weeks later, then another small bowl a week or 2 after that I don't remember. I test this monday and I'm hoping I'm clean enough to pass. I'm looking for the one that is closest to a DOT UA test. I feel like I'm clean, I just want to 100% sure.
