How long will it take to get the TCH out?

Alright, I smoke weed like a damn chimney, but recently i got caught by my parents, about one month and a week ago. So i planned on quitting weed on the last day of school, one last session with all my buddies. this was on 6/9/10. I smoked about .5 grams to the face. My dad is really smart when it comes to drugs since he grew up around them and kept himself clean. So he realized i got high, he has a drug test and he said hes drug testing me (by my piss) and my excuse was its still in my system from the time i got caught first, wich was about two weeks ago from 6/9/20. Now im grounded for the summer, he said if im clean in two weeks ill be out and earn his trust back. So now i need to know, how long will it take? So heres more details... I workout allot everyday, i dont do much cardio except for swimming and jump roping. I drink allot of water, sweat allot, and recently been eating allot. Im really tall and not too skinny, but cut. Id say my metabolism is really fast since i **** like a horse. Please give me pointers and other things to do? ONE LAST THING: smoking cigarettes speeds up your metabolism, so i hear, and i smoke allot, but i quit as of today because of this girl i think i might be falling for, well attempting to quit to be more specific. Help me out, will smoking cigs clean me out faster? I love you guys, and please no bullshit answear like "shoulda not smoked in the first place" or "smoking is bad" i know that you ignorant morons out there, thats why i need some professional help.
