How long does Marijuana stay in the system?

31 Jul 2009

As a rough guide: if you smoke the occasionally joint, it'll stay in your system for up to 10 days. If you smoke regularly, up to 45 days and if you smoke constantly, 90 days.

As for being detectable in a drug test, well this depends on the type of drug test. Urine test will detect up to a month prior but a blood test will show positive if you've smoked any weed in the last 6 months.

Also important to note that marijuana residue is stored in the fat cells, so if you're skinny or have a high metabolism, the time it takes to leave your system may be reduced.

This is a difficult question to answer. Detection of marijuana or its metbolites in the urine depends on many factors such as drug potency, tolerance, patients condition, fluid intake at time of test, method and frequency of marijuana use, patients metabolism etc etc.

It is impossible for anyone to estimate the time it would take for someone to test clean. The best thing you can do is if you know you have a drug test coming up stop immediately. You could also test yourself twice weekly and when you have your first clean reading you would have a resonable idea of how long it takes for you to clear marijuana.

As a general estimation if you smoke rarely your urine may be clear of metabolites in less than 1 week and if you are a more frequent user it could be anything beween 3 and 50 days.

It is worth noting that marijuana metabolites are stored in fat tissue so those users who are overweight will probably take longer to clear the drug.

The first answer is correct. It really depends on how much you smoke or smoked and your metabolism. If it is a urine test, you can drink alot of water the day before and day of test to flush it out. I have done it plenty of times to know that it works. I am not condoning it but its some help. Also if it is a hair test its there for good.

I agree with the first two posts. i do not use marijuana on a regular basis anymore but at a time when i did i tested negative after 7 days clean. I am skinny and have a high metabolism. It would also seem logical-I say this because i cannot be 100% sure on this, that if you consume fatty foods or foods with a high level of carbohydrates while "high" and remain innactive it will stay in your system longer. Marijuana is one of those drugs you can never be sure about in these regards though and there is no rule of thumb when judging an amount of time to stay clean to pass a drug test.

hi there I´m 41 years old i have been clean for 8 years now, and was addicted to almost every durg out there ... started with the occasional joint, the problem is not how long it stays in your system, the problem is that in time you are killing brain cells( becoming a walking zombie), and the worse is the mental dependency ( first twice a week ... then believe me everyday and more than one joint... tolerance) and the worst is that it opens the doors for more hardcore drugs. I wasted 20 years of my life 2 wives my children ... MY DIGNITY.

My advice to you as you seem young is to stop now, while you have time and stop worrying about how long TCH (is what gets you high) stays in your system.

if you are not currently using marijuana and you use it one time ONLY ( one joint or one pipe load) it will take 3 -5 days for your system to be cleansed of the medication. if you are not currently using marijuana and use it several times over the course of 2 -3 days it will take approx 2 -3 weeks after for your system to be cleansed of the medication. if you are a regular daily marijuana user it will take 1 - 3 MONTHS after stopping the medication for your body to be cleansed of it. if you are overweight it will take longer than if you are a normal weight for your body to cleanse itself of the medication as THC ( the active ingredient in marijuana ) is stored in the bodys fat cells. also the heavier your use of course the longer it will take for your body to cleanse but regular daily users should expect a minimum of 30 days for your body to cleanse.

depending on how much you smoke it can stay in your system for months. also depending on how much thc is in the bud you smoke. but if having to take a piss test id say about a good 2 or 3 weeks before while drinkin lots of water should do the trick
