Today i had a drug test for college, if i fail i'm pretty sure i get kicked out. The last time i smoked was 33 days ago but i am 300 pounds and weed stays with me for a long time. i drank 1 gallon of water last night and 1 gallon this morning then 4 hours before the test i ate 4 asprin then 3 hours 20 min before the test i drank the triple strength 32 strip natural cleanser, and the another 3 quarters of a gallon of water and then an hour and a half before the test i ate another asprin but an hour before the test i puked. the detox said it starts to work in 30 min. so should it already have kicked in? please give me feedback anything to ease my mind!!
