How long does cannabis stay in your system?

...

Tiibii	idk quite how long.. but maybe a week or two is my guess.. LSD stays in 10 years.. lol

AJDarkstar	About 3 months, I think. Maybe longer.

corsa7777@btinternet.com	why did you put it in your sistern thats the first place the cops look

Debbie Fancourt	cannabis can stay in your system for 3months- a year. it comes out of your body through your hair folicles.

t11omo	It depends what type you smoke, how often and how much. Usually around 30 days if you're a moderate smoker. Why? You got a drug test coming up or something? x

taz	6 months i should no i smoke it all the time

fire	Cannabis can stay in your system as long as 28 days or more. It is only illegal drug which stay in your system that length of time.

rosbif	It gets incorporated into new hair growth, so in theory you could test positive from any hair which was growing on your body at the time you took it. Hair has a long lifespan, so give yourself a lot of time before any compulsory testing!

A Teesside Smart****	The length of time that it can stay in your system varies but basically it is until the package falls out of your anus - to the delight of the customs officer.

ste l	if you are a hevey smoker it can be pickt up in a piss test up to a cupple of months away if you just have the odd toke dont worry about it . it can show up from hair samples for a long time but the test is expensive to carry out so unless you are up in court or something. dont worry about it. the girl who talks about lsd stayin for ten years could not be more wrong its gone out of the blood streem minuets after you took it same for mushromes its weird but you could be triping your face off the same time as being tested and nothing would show up hope this helps and remember next time "just say no! " lol

college girl	Long enough for your parole officer to revoke your parole.

reflection	if you dont use it it wont show up

apple_islegirl	i quit smoking 6 years ago and i still feel like a stoner lol trust me it fries your brain! dont do it!

shagkitten21	in my brothers case all the time ! lol i think its a bit like alchol & stay in the system for about 24-48 hours...

flippant	it can show up inblood tests 3 months later

Ah!	It depends how long you have been smoking it for. It's anything from 1 week to 50 days.

Professor Science	forever

stygianwolfe	well you got plenty of answers and some are on the money it stays in your system 28-30 days at an unacceptable level for employment but it can last in your fat cells about 5 months in low detectable amounts...the local head shop can have a flush system if you feel you have to hide you use..ps your hair is a different matter,it stays for a looong time

EoinDM	I heard 6 weeks.

textkitten	my husband has just had a random works drug test(passed lol) and asked the tester the same question, the answer was 4 weeks in a urine sample. The police test is a bit more intence and Cannabis can stay present in your hair dna for up to 2 years!

angel afraid and sad	it stays in your actual system for up to 14 days but stays in your hair follicles for 7 yrs

Izabow	it last 7-10 days depending on how much you weigh and how much water you drink and sweat out! If your a real heavy, heavy smoker it could take more water and sweating to get out of your urine and or system.

et929	It depends on your frequency of use. A daily pot smoker can usually clear their system to an undetectable level in 4-5 weeks. Using golden seal and other such herbs will shorten this time by about one third. However, many drug panels include a test for these masking agents as well, so be carefull. If you are a casual smoker (once a week) it will take about 2 weeks for it to clear to low enough levels.

sean	will show for 28 days if heavy user in urine..... believe some new tests can detect it even longer than this.

Munya Says: GFOD	simple answer: up to 30 days OR LONGER depending on frequency of use and length of use.

-x-lil-kate-x-	Depends on your body, and how much yuo have taken.

Ray D	Depends on how much you smoke, weekend smoker drink alot of water or OJ maybe a week, Daily smoker up to 2 months, and theres not to many ways to pass drug test now days, they also look for " flushes and cover ups "

selbysupper	Not long if you drink water same goes for hard drugs this is how addicts in prison fool the authorities

KIMBERLY Clayton	If you really wanted a good answer you would need to let people know why you are asking, as far as what YOU mean by "in your system". Legally, the term "in your system" means detectable by any known test. If you mean to ask how long it actually impairs or affects somebody, it depends on the individual, the strain of Cannabis, how it was used (smoked or ingested), and lots of other factors. The normal amount of time for smoked Cannabis would probably be about 3 to 6 hours. Cannabis is tested for by measuring it's metabolites (what your body produces when it is exposed to marijuana). The metabolites cling to fat cells in your body, and slowly "trickle out" through sweat, urine, etc. and can be detected in urine up to a month or slightly longer in heavy users, or might not show up in sufficient quantities to "test positive" even the next day in a VERY light user. Drinking LOTS and LOTS of water will help cleanse and also dilute the metabolites in your system so that a negative (passing - that's what you want, I think) test is more likey. Also, the urine from the middle of your stream will be "cleaner", so if you pee a little in the toilet or whatever, then into the cup, then finish into the toilet, you'll get a better result. Your first urine in the morning has more accumulation, so go to the bathroom BEFORE the test a few times if you can. If you had a lot of water and your urine is too clear, it will be considered suspicious, so taking a vitamin-B pill is a good idea, because it will make it more yellow. If the test is from blood or saliva, Cannabis should only show up for a few hours after using it; Maybe up to 48 hours after, but usually less. If the test is taken from a hair sample (shaving your head won't help - they could still test body hair!) it can be detected back from any point that that hair was growing on your body. In other words, if your hair was 18 inches long, and you had hair on your head today that was also growing there two years ago when you smoked some pot, you could test positive for Cannabis detected "in your system" today. Isn't that just WRONG? But most testing centers or employers only test between 1 and a half to 3 inches of hair, meaning maybe 90 days or up to 6 months. So stick THAT in your pipe and smoke it!
