You quit smoking marijuana 1 monthe ago you took two hits yesterday how long will it take to leave your system?

30 days. if you are a habitual smoker, it is much more than that. tips for a drug test... drink gallons of water... seriously... water water water. take some vitamin c and b, and add vinegar on some of your foods. also, work out... the more you sweat, the faster your metabolism, and THC is stored in your fat cells. also, day of testing.... pee first... then drink at least 20 oz's of water, and don't pee again until test.
