How long is THC detectable in urine? If you are a chronic marijuana user, THC can be detected in your system using a urine test for up to 12 weeks depending on the quantity as well as frequency of use. Note that if you just used marijuana once and stopped, you can still test positive to a drug test.
On the average, THC can be detected in the urine of a casual user during 2-5 days, 1-2 weeks for usual users and up to one month for heavy users. In the blood marijuana usually stays only 1-2 days, about 24 hours in saliva, up to 4 weeks in sweat, and in hair it can be detected for up to 90 days.
