The amount of time that THC will stay in your system varies from person to person and circumstance to circumstance, and falls within the rather wide range of 3-90 days. On average, it will be detectable for 30 days, which makes marijuana one of the slowest drugs to vacate your system.

Many factors affect the amount of time that marijuana will linger. These include your age, weight, metabolism, overall health, activity level and the frequency with which you use the drug. The method you use to take marijuana might also influence the amount of time that it remains in your system, with ingested or consumed pot sticking around a little longer than pot that is inhaled.

Why does THC take so long to clear?

Simple. Marijuana, and thus THC, is a natural substance. Your body doesn't reject it the same way that it rejects manufactured substances. THC is also sticky; it adheres to your lungs, fat cells and hair follicles, and your body has a difficult time breaking it down so that it can be expelled from your system. This is why your weight and marijuana usage habits are so influential over how long THC will remain in your body. A person with an abundance of fat cells will rid themselves of THC metabolites at a slower rate, while one who uses marijuana with moderate to high frequency will experience a build-up of these metabolites, leaving them with more to expel.

One way to speed up the process is through the combination of physical exertion and a liquid flushing of your system with water or cranberry juice. See, THC normally resides in your fat cells until they are burned, after which the THC will enter your bloodstream. Eventually, it will exit your body through your urine. Thus, a one-two punch of exercise and urinary system cleansing could reduce the amount of time that THC remains in your body.

Otherwise, yes, expect it to remain in your system for anywhere from a few days to a few months.

It really depends on how often you smoke.  If you do it about once a month it can be gone in less than a week, especially if you have a high metabolism.  I wouldn't rely on that though, just stay on the safer side.  More habitual users can take about a month to get it out of their system.  I've never heard of anyone failing a drug test after being clean for a month.  Even in daily users.

Not that your information isn't generally correct, but when I went through drug classes following a paraphernalia charge, I went without smoking for TWO Months before my weekly drug test finally came up clean.

It totally depends on how much you take, how much water you drink, how
much you weigh, and how much you exercise. If you just smoke a few
hits, drink a lot of water, and exercise, it can be out of your system
in less than a day if you don't have too much body fat.

If you smoke all day, every day, it can take up to a month to get out of your system, especially if you don't exercise.
It is possible to smoke every day (all day) for twenty years,then pass a hair strand test a month after quitting, even though it's supposed to go three months back.

THC (Tetrahydrocannabinol) can stay in a person's body for as long as 3 to 90 days after smoking or being ingested orally. There are numerous determining factors for how long drug toxins stay in a persons body which vary from person to person, such as the analytical method used, your health, your body weight, metabolism, fluid intake, the type of drug toxin, and the degree of exposure to the drug toxin.

Delta-9-Tetrahydrocannabinol or THC, one of nearly 400 chemicals in a cannabis plant, accounts for most of marijuana's psychoactive, or mind-altering, effects. The strength of the drug is determined by the amount of THC it contains which varies from plant to plant. Marijuana stays in your system for different amounts of time depending on how often you smoke it, how much you smoke, and the makeup of the individual (weight/height/etc.).

I agree with everyone who answered your question. I believe it stays in for at least 30 days, but it does depend on your weight, what you eat, and if your flushing your system with H2O, etc. All of it counts.

The amount of time depends on how much you smoke. A casual smoker will be clean in about a week. If you wake and bake then burn all day it's going to take from 30-45  days to be clean.

Weed shows up, it all depends on your body and how fast it can kick out the fatty cells. Working out should help a bit.

I know people who have done it, and its stayed in their system for a week. Now if you drink a lot of water, high metabolism and exercise daily, it will probably get out faster. Also, urine tests will come up negative if you drink a lot of liquid

THC will be traceable in your system for 3 months or more, but whether or not it will show up depends on the type of test. Exercise will not help remove THC from your system - the best option is to not smoke dope!

I had a coffee shop in Amsterdam for 17 years, so I could tell you some horror stories about smoking weed.

It usually depends on your weight, metabolism, how often, ect. In most cases though it will be out of your system in 1-2 weeks. But if your smoking every day for 2 weeks it will be about a month unless your lucky. Good luck and HAPPY 4/20

It actually depends on the type of test. Blood, urine, hair? For urine it will typically stay in your system for 30 days and can show up on a test within an hour depending on the type of test they are using. Some companies make the tests differently. Note; if you are a regular user then those can stay in your system up to 45-60 days. If you didn't do it then you wouldn't have to worry about any of this. Maybe its time to grow up.
