I,m 5,8 around 124 pounds, have a fast metabolism parents wanna THC test me! ha! been 2 weeks since last toke?

I get plenty of exercise and for the past week or so I've been drinking a fair amount of green tea, tasty:) lol. I had the flu for a week or so before i got caught so I didn't smoke during that time. Have only smoked twice in the past 3 1/2 weeks . Smoked my stuff almost every day and thoroughly enjoyed it for about three months. How much longer? might i be safe now?
