How long does marijuana stay in the body’s system?

The actual answer depends on the method of testing, how often and how much marijuana you have consumed, and your body fat and weight. Once consumed, your body begins to break the components down and naturally removes the THC from your body. Regular use of marijuana, more than once a week, blood testing can detect the active THC in your blood and can last in your bloodstream for up to two weeks.

Higher Levels of THC

The higher the levels of THC in your blood indicates recent marijuana use. Urine testing is harder to put a timeframe for THC to pass through your body’s system. Unlike blood testing, urine testing does not test for the active THC but rather THC-COOH, the non-active component that is left behind in your body after processing. THC-COOH is stored in your body’s fat cells and released through urine over time. Since each person has a unique body size and fat content, it ‘s hard to pinpoint the timeframe to remove marijuana from the body.


Based upon the regular use of marijuana, more than once a week, you may test positive for marijuana from 7 to 30 days past your last use. Although, some heavy users reported it staying in their system for up to 90 days. Hair and saliva testing are not always considered an accurate way for testing. Marijuana will show up in hair samples around seven days after use and linger for more than 90 days.

So are you screwed?

The chemical compound needs to bind to the follicle to get an accurate test, and that does not always happen. Whereas saliva testing is a relatively new testing method that can reveal a positive test within 1 hour up to 12 hours of the last use. Hopefully, this information will calm your nerves when your new boss says “Congratulations, you have the job! Now time for a drug test,” but if needed please refer to the chart above for more assistance.
