So I am leaving now to go get a 10-panel drug screen. The last time I smoked was on New Years Eve. Since Then I have run about 15 miles total. I weigh 150 with around 12% body fat. I also just drank that nasty ready clean vitamin drink and have been drinking plenty of water. One thing I am worried about is I ran 2 miles this morning (like most mornings). I just now ready some posts saying not to be physically active before the test because it releases the THC metabolites out of your fat. (which i have 12% of). Before this I was a pretty regular smoker only skipping a day or two here and there. Im planning on using my midstream pee for the test and have drank around 64 oz of water since 8 am this morning. For the first week my sweat reeked of pot. That went away after a week and a half of rigorous exercise. So what do yall think? Anyone who has had success care to share? Should i pop some b12 before i go in?
