This depends on the health of your own body as well as the amount and type of weed you have taken. Some people believe it can take anywhere between three and 90 days for it to leave your system.

There is however, no straightforward answer to this question, as some forms of weed can be stronger than others. Therefore if you take a stronger dose, it is likely to remain in your system for longer than a weaker dose.

Stay Healthy to Get Marijuana Out of Your System Faster
In the same way, if you smoke a lot of cannabis, it will take your body longer to be totally rid of it. The health of your body will also determine how long it takes for weed to leave your system. If you get plenty of exercise, don't drink too much alcohol, and don't smoke cigarettes, your body will be quite healthy.

Eating a rich and varied diet with at least five portions of fruit and vegetables a day will also help ensure you have a healthy immune system. The healthier you are, the more likely your body will be able to eliminate marijuana from your body at a faster rate.

If you are slim in build and have a faster metabolic rate, it is more likely that weed will leave your body faster. You can try to speed up the process by drinking plenty of water and eating well. Also, getting a lot of exercise may also help the body restore itself.

Okay look, I am 125 pounds and have a fast metabolism and I smoked a week before about two blunts worth, and then Friday the day before my test I smoked a blunt, then drank about six glasses of water and cranberry juice.

The next morning on my way to the drug testing I brought a bottle of water with me and drank that and I ended up passing. It does all depend on your weight and stuff but I think it was unbelievable what happened to me.

So if you're not like super big or anything, then it could take anywhere from two days to one week. I am also a regular smoker if that helps any.

I smoke weed everyday, multiple joints a day. I am in shape and have 3% body fat. I have never failed a drug test that I know about. I have failed one drug test that was random and I had no time to prepare.

I even smoke the day before tests, all I do is drink as much water as my body will allow on the day of the test, starting as soon as I wake up. You will know when you have drunk enough water when you feel like you have to vomit.

When you get that feeling drink more water. Wee numerous times and when it's clear you are good to go. Like I said this has worked for me like a charm for probation drug tests (which was sent to the lab), and drug tests for jobs which are usually done with the dip-stick.

The most important factor to calculate it would be the health and the type of weed smoker.
Weed can stay in the body for a longer time if the user has a slow metabolism rate and he weighs over 200lbs.

The Half Life of THC, the main ingredient in weed is about 10 days, so for a normal person it can be stay in the body any time between 2-9 days.

We all know that waiting on the results on a urine analysis sucks but I myself have passed many drug test for THC within 14 days. I'm on probation and all I smoke is high grade dro. I smoked for 13 days a couple bowls a day or I would smoke a couple hits of a cigarillo.

I weigh 225 pounds, but am not fat and work out five times a week as well. What I have also learned is that drinking a gallon of water while you are on your "detoxing" of the THC works. If you have access to a steam room or sauna that helps tremendously as well.

I just detox naturally and I've never used detox drink. It all depends on your metabolism, how active you are, and how much you smoke. All in all it's not worth the stress even though I love smokin' that dank. Hope this helps.

Cannabis is known to stay in the system for 28 days. Coming from a pro, between you and me, if you have a high intake of pure orange juice and other vitamins the THC is covered up and released from your system faster.

Depends on how much you smoked, if you were completely clean when you smoked, then it should be out before a week for a urine test, tops. Otherwise, if you did smoke a lot before that, it will be anywhere up to a month.

If you smoke weed a lot it will take 30 days to get out of your system. If you don't smoke it much count on 3 days to 2 weeks.

On a urine test, you should be clean within 20 days if you drink water a lot, and before the test also drink a lot so if there is any THC left, the water will flush it out. Basically drink so much it probably wont even pick it up. Good luck man.

The NHS believe it stays there for 30 days, however drinking lots of liquids also helps it to get out of your system quicker.

It all depends on the amount of THC in your system and your weight. THC stores in fat cells, therefore if you ar petite it can be out of your system in as little as three days, if you frequently smoke THC can stay in your system 30+ days.

I'm on probation and have passed within one day just by drinking about 5 big cups of water. Also if you're in shape it takes about 20 days tops to get out of your system unless you smoke daily. I have another drug test and I took about 2 good hits off a bong and am going to try the drink water like there's no tomorrow method, and hope it works again.

Well depends on if you're a large person or a skinny person. If you are going to smoke weed do it all at one time it will take less time to get out of your system.

THC is usually detected in a urine test for up to at least 30 days after using. You can try drinking a whole lot, and I mean a lot, of water, and whatever else in addition to the water. I have seen on one occasion this worked for someone who passed 2 weeks after smoking pot.

Normally though, this isn't something that works. Takes ABOUT 30 days to get out of your system and I have been told by a counselor that drugs tend to filter through the blood (blood test) faster than urine (urine test).

If by some crazy chance someone is giving a hair test, well then pull a Britney Spears and shave your head, because depending on how long your hair is, these hair tests can reveal previous use of drugs a long time after you have used them, a LONG time.

But hair tests are not the norm for giving drug tests because they are way too expensive. So I wouldn't worry about having to shave your head any time soon.

Well, bad news! I smoked high grade week once a day for like six months, sometimes every other day and went clean for seven weeks and took a urine test and failed (got the results this morning).

I'm 5' 9" and 205lbs I learned that the THC stores in fat cells. I read that If you exercise regularly it helps, but I did everyday up to the test. Its like this: If you are on the heavy side them you might be screwed!

When you exercise and lose weight the fat cells are broken down and the THC is released into the blood stream. After seven weeks, the Doctor told me that my THC count was 100 above average. So in all reality about 90 days should be a definite. Otherwise it's all chance! Hope that this helps.

THC can be detected for up to thirty days if you are a regular smoker (regular meaning daily). If you're a much more casual user, it can be gone in less than a week if you take the proper supplements and get some exercise.

B vitamins will help to clean out your system. If you go to a smoke shop, they usually sell detox drinks that do the trick, but it's much more affordable to go down to a GNC or Vitamin Shop and pick up a bottle of Vitamin B and a bit of Niacin.

Usually a month in your urine, and three months in your hair, even if you do only smoke once a week.

It depends on the amount that you smoked. Was it a one time thing, or have you smoked for a week straight? That's the difference.

It will also be in your hair until you cut off the hair you grew while you smoked it. That is why Britney Spears shaved her head. A lot of big employers are now taking hair samples for drug testing.

Good method that has worked for me at 125 pounds with a fast metabolism is to drink massive amounts of coffee. It will make you piss like a race horse but worked on a lab test (normally) when I stopped smoking 5 days befor the test. 

Almost the same concept as drinking water to dilute except it won't distort the color with the urine staying its normal color. This method does work if you drink coffee more than the normal just in the mornin.  Drink it all day.

I have been on probation for the past 6 months and I have mastered detoxing myself. Basically, it is not THC that is measured in your system it is a co-existing chemical that is part of the make up of marijuana that is tested for. What I have learned through out these 6 months is all drug tests are different! If your test is sent to a lab, they count how much is in your system between anywhere from 25-50. If you are completely clean you can smoke 3 days before and pass it no problem due to the chemical in your system because it has a half life. Although, if it is not a lab tested screen the counts can measure anywhere from 5-15 which is not very likely to be out of your system in 3 days. This is more likely to take a week to be able to pass. If you know you may be drug tested soon, fill up a gallon of water add ice if you feel and cut up a lemon, 6 strawberries, and a couple pieces on mint. Not only is it good tasting but the nutrients found in these items help you to detox at a rapid rate! Hope it helped, be smart about it though. X

Too late to think about this now as traces will show but not an amount so tell them you were at a party where there was second hand smoke.

It's hard to say. If you are not a regular user and just did it once, it could be out within a week. If this was over a period of time, it could take a month or more to fully be out of your system.

It all depends on your metabolism, how much food you eat, what you drink... The quality of food and drink. The amount you smoke daily, exercise helps too - everyone is different.

My understand is if this is your first time then it may take 3-10 days. However, if you smoke it say 2-3 times a week for say 3 weeks then it would take almost 45 days to clear your system.

If you smoke weed weekly then it's always going to be in your system - it takes a month to leave your body.

It depends on your metabolism, and also how much you exercise, the food you eat. What I recommend is lots of weeing and water, and not smoking in the first place would be the most helpful. Forget antioxidants, THC is an antioxidant itself.

If you don't smoke often it should take about 2 weeks. If you're a regular then it would take about 45 days or more.

****Marijuana can be tested for with blood and hair samples too, and they all have different time frames***

It averages 30 days in your urine. If you are a regular user or you are overweight it could be there longer. The metabolite that they are testing for is fat-soluble, so if you are fat, it will be there longer; if you are skinny, a shorter period of time.

I use to be a daily smoker but then i stopped about 28 days ago. I didn't try much to get it out of my system because i wasn't worried about it. Then i started looking for jobs and i got a job and i took a drug test totally forgetting that i use to smoke pot. A couple days before i took the test i was drinking water all day. It had been 28 days that i didnt smoke pot. I'm 5'1" and 135 pounds.

4-7 days for a blood or urine test, if used regularly about 30 days, but if used everyday it can take up to 90 days to get out your system. However it can be detectable in a hair test for longer, it depends how often you cut your hair, but if you don't cut your hair at all it can stay their for 3 years. For armpit, leg, chest, pubic, etc, hair it can stay there for longer as the hair takes longer to grow, but normally about 7 years, or up to 12 years for very regular users.

Seven years - it will leave your blood a lot sooner but for it to be completely out of your system it will take around seven years, and it's in your hair.

It would normally take 6 months and it doesn't matter how much weed you smoked if it was just 3 drags of a whole spliff it's still going to be in your system for 6 months

Better question, why are you using it so often that you're actually worried about this?

I know the popular idea is that weed has no effect, but it does. It makes you stupid enough to believe it has no effect, and stupid enough not to notice the effect until it's gone.

Stop using that s**t.

Marijuana can stay in your system for 3 to 90 days!! Depending on how much you smoked and which method you uses to smoke it, how offten you smoke and how fast your metabolism is. Depending on the type of drug testing as well. It can be found in you hair for up to three years after the last time you smoked.
