okay since you had a few puffs you should be so fine i wouldn't worry for the world...your DT might show a little sign off marijuana/thc in your system so just keep drinking lots of water and urinating daily, you can tell if you're still THC'd by your urine, your next bathroom trip look at your urine and see if it's a Darkish yellow...although if you do Sport and you come home and you have to go..it will be yellow since you've just exercised so don't worry about that part..basically i'm just saying 'The less yellow, the more you should mellow' So exercise, drink lots of water and you'll be A-O-Kay. good luck
