How much pot do you need to smoke to fail a urine test?

VERY VERY LITTLE if your a heavy smoker it could take up too 3-4 months to get out of your blood. for piss up to 80 dayz *note* i could be wrong about this but its something like that

lets say a 1 PHAT HIT lol a joint every 4-5days might be fine but i could be wrong again

I fucking hope not 80 days....ive been clean for 26 and i might have a piss test next week. I don't know if I would define myself a heavy smoker though, probably an 8th a week.

I must be the lightest pot smoker on here. With the shit that I smoke, I only need to take one small hit in order to be stoned for a couple hours. I have been smoking the same joint for a week now. I've been getting stoned like once or twice a day too. HAHAHAHA, its the killer homegrow!


So do you guys think I would pass?

drink oj, vinger and pickle juice that will help %65 to clean. never get too cocky do u really wanna go to jail, lose your job over weed or whatever the case would be?
heavy smoker is alleast a g a day. like again i could be wrong

not the drinkin part it really help your body. also note that thingy that flush your body ONLY WORK ONCE THEN NEVER AGAIN its about $60-120

for piss test its differnt i heard it come out a faster but i forgot what the rate is

A little perspective here. Going by this poll:
Poll-How Many Grams A Day Do You Smoke?

you're an average smoker in respect to these forums.

Now, the time it takes to rid your system of cannabinoids that will sow up in a drug test depends on your fatty cell levels. THC and other cannabinoids are stored in your fat cells and slowly excrete as the days go by. Problem is, THC has a seven day half life if I recall correctly. This means that in 7 days time, half the THC that you ingested last week will still be in your system. But it gets more complicated. If you smoke again, then you will have what was in your system, plus what you've just ingested. Then in seven days, you'll have half the total amount from that time...get my drift? I know, I don't explain it at all well do I.
(I'm getting deja vu here).
Try this very unscientific explanation. You've just finished some wikkid weed and the detectable THC levels in your body are at (an arbitrary figure of) say 10.

day 1: Levels are at 10
Day 7 (IF you haven't smoked all week): 5
Day 14: 2.5
Day 21: 1.25

OK, now what if you smoked on day seven and got say, a THC 'dose' of 8
Day 7: 5 plus 8 = 13
Day 14: 6.5
Day 21: 3.25

and so on. Unfortunately, trying to put an exact or even approximate date on when you will be 'clean' is pretty hard.
Oh, and because THC is fat soluble, no amount of fluid flushing will help as far as I am aware.

Personally, as a usually 1 to 2 gram a day smoker, I wouldn't expect to pass any test (other than our new tongue scrape tests here in Oz) for at least 30 days...at the very least, and I am only a small bloke (at present under 60kg and no fat on me to speak of).
