If you smoke weed how long does it take for it to be completely gone from your system ?

misspipik	six months if they do a hair follicle test.

WiseGuy	Depends on how much u have smoked it, but the max. time period is 40 days.

jonn449	It makes you stupid forever!

rat---the@sbcglobal.net	Many factors come into play! First consideration is what level is being tested for! The Military is a serious one-6 Months! Blood or Urine? Hair? Depending on how much fat you have, how much Cranberry or other antioxidants you consume? If you have "Flushed" your system? Bleeched your hair? Me, I just tell people that I am a graduate from Hawaii and a Surfer-What do you expect?!!! As George Clooney say's "Yeah, I did that"!!!!!!!

digitalchaos000	its up to 30 days dude, i know i had to stop because of court and such. if your really looking to mask it you can go buy a drink or some pills that will clean it out of your system. drink a lot of water that helps too. plus it also matters how much weed you smoke daily.

oompa	that is a complex thing. depends on age&body type/weight. also how long been smoking/how much each day. general rule: smoking a little ie 1x 2x a week and small amount and for 1-2 wks = out of your system in 3-7 days. heavy use ie every day or a couple big blunts in the last week could take up to 30 days. One use with out any prior use could flush in 24 hours. i assume you are talking about a piss test. blood test is more likely to screw you, and a hair follicle test can show positive for 3-6 months after. If you dont have much in your system you might want to load up on Niacin (supplement try GNC), cranberry juice and lots and lots and lots of h20. that should clean you out in 72 hours *no gaurantees a piss test is simple to beat depending if they send it to the lab or use the cheap one right there. 1. dip your finger in a 50% bleach solution and let it dry before you test, dip it into the cup when you piss. (not to much or it will show wrong) 2. take some test clean or whatever its called (availible at your local smoke shop) and follow the directions 3. buy a whizzinator its a fake ding dong and load it up with clean piss or try to bring it in a ziploc (risky, make sure you keep it in your pants so its room temperature)

LIBERALS ARE SUCH DOUCHE BAGS	it depends on the amount you smoke, and your content of body fat. if you're a fat ass, and you're chiefing everynight, it can take a month or longer. if you're thin, and you rock the ganja it can take less time. i'd say just stop smokin' all together. it's a waste of time, and money. do something more resourceful with your time, like learn about something. educate your mind, don't waste it away. drinking ALOT o' water, and eating vitamin B pills can help speed up the cleansing process as well.

Dan B	This really depends on a few factors one quality of marijuana two how offten you use three fatty tissue.thc is measured in nano grams the more nano grams the longer it takes to get rid of it stores in the fatty tissues of the body that is why niacin will help get it out of your system 30 days of no smoking and alot of water drinking 1 to 3 gallons a day should get even the heaviest longest term smokers clean and then there are all kinds of alternatives sure gel works for some people niacin and water the original whizzinator is awesome www.whizzinator.com without the use of any products and no drinking tons of water and smoking chronic for yrs plus it would take months of not smoking before you were clean 3 to 5 months for sure . hope this helps

DVINE L	It is more likely to stay in your system for days, weeks, or even an entire month after the last time that you smoke. Itâ€™s argued both that THC never leaves your brain. The speed at which marijuana leaves your body depends both on the speed of your metabolism, as well as on the half life of THC. Your metabolism and how much marijuana you smoked will also have an effect on the length of time that it will take . The most common period of time is anywhere from 3-30 days, depending on your metabolism and the amount of marijuana that youâ€™ve smoked.

J Somethingorother	30-35 days minimum. No way to hurry it.

marion r	about 2 weeks less if u drink lots of water cranberry juice and some vinegar

libsuksht	30 days,more if you have alot of body fat.

hawndawg	6 weeks

ResyG	30 days. Why, did you smoke some??

pinwheelbandit	It depends on how much you smoke. If you smoke habitually, it will take approximately 30 days for a urine test (up to nine months for a hair follicle test). If you smoke just once it only takes a few days for a urine test.

Big C	When I was a Drug and Alcohol NCO they said Basically about 72 hours. But if you are a fat person it would take longer cuz the TCH stays in the fat cells longer. The hair follicles up to 3 months. But this was in 1990. Technology may detect it in a longer period.

Mr. Lemur	about a month for your urine but if someone was to take a hair follicle you it would be up to seven years

obscene and vulgar	never all drugs you ever take are stored in your spinal fluid (including perscriptions and caffine) but you should pass a test after about 3 weeks. you need to be shot for doing drugs anyway dumbass

Sterling403	I think about 30 days. It can be detected in your hair for a lot longer. Might want to consider a buzz cut.

caciansf	I herd that it takes months because it is fat soluble and it is stored in fat cells. Harder to get rid of I guess.

amaka U	you shouldnt smoke weed, not good for you

Jen	up to a month

krayzie_boo11	i always thought it was about 30 days for a blood test

Automatic Slim	It's out of your system in 24-30 days.

tchaffee	A friend told me about 2hrs to end your high.
