1. How Long Does Weed Stay in Your System?
If you are an existing marijuana user, or are considering starting, the question of "how long does
weed stay in your system?" is probably one you have thought of. Whether or not you have an
upcoming drug test for work, or are just curious, we have the answers.
Metabolic Breakdown of THC
There are a variety of factors that contribute to the metabolism of marijuana and how long it will
remain detectable in the body. Some of these factors are: body weight and body fat percentage,
metabolic rate, frequency of use and the amount consumed.
Testing Procedures
Testing procedure can also have an effect on the outcome as different detection methods
search for different cannabinoids or through different measures. For instance, one of the most
common test is a urine test, whereby the presence of THC-COOH (a metabolite of THC) is the
main search parameter.
In case you are not aware (because I wasn’t!), THC-COOH is by-product of the liver that is
excreted during the process of breaking down THC. Most drug tests have a baseline for which a
person is considered to be positive for marijuana use. Typically, if there is 50 ng/mL or more
THC-COOH in the urine, a person would test positive. However, in some cases, a level of 15

2. ng/mL could be high enough to generate positive results, while in other users a level of 100
ng/mL is necessary to test positive1
.
As you can see, there can be quite a variety of results.
User Frequency
The next consideration is the user frequency, which is likely one of the most important factors in
determining how long weed will remain in your system. Users fall into three categories:
Occasional, frequent and heavy.
● Occasional users will find that THC-COOH is detectable in urine tests 1-3 days after
marijuana was last used. By the fourth day, the THC-COOH level usually drops to 50
ng/mL or less and will have negative results.
● Frequent users can test positive for marijuana for 7-10 days after the last use. Typically
after the 10-day mark, the THC-COOH level has dipped below 50 ng/mL and will have
negative results.
● Heavy users can expect to test positive for THC-COOH for extended periods.
Particularly heavy users will show THC-COOH levels for several weeks or a couple
months from the last use.
You can also use the chart below and determine your metabolic rate for marijuana based on
your body fat percentage and frequency of use.

3. It is also important to note that if you are dehydrated, that will concentrate the urine. This
increases the likelihood that a drug test will be positive. In addition, users that exercise
frequently may also have an increased chance of a positive test as exercise breaks down fat
cells, thereby releasing THC. These are good to keep in mind if you have an upcoming
cannabis urine test.
Related Research
With that said, we took a look at some of the data on marijuana and THC testing.
A 2005 review by Paul Cary, director of the Toxicology and Drug Monitoring Laboratory at
University of Missouri, noted that detection times beyond 30 days are largely an exception.
In an older 1989 study of chronic users found that there was a maximum detection window of 25
days with a 20 ng/mL test sensitivity. In addition, it was noted that just “one subject tested
positive after 14 days, and it took an average of just 9.8 days before cannabinoid levels were no
longer detectable”.
Lastly, a 1984 study that also tested chronic users against the 50 ng/mL cutoff, had results that
showed it took 40 days to get clean and that 8/10 participants showed a negative test result
after 13 days.
