How long is THC deteceted in urine?

Answer 1

THC is non-existent in urine, when screening for urine it is only the metabolites and byproducts of the drug that are tested for. For a frequent user, the substance may stay in the system up to 40 days after abstaining from use of cannabis or cannabis containing substances. For seldom users, the detection period is from 2-10 days. The metabolites and THC are stored in fat, so the less fat you consume and the more fat you burn, the faster the drug will decrease in content. From a drug test manufacturer:

Cannabis UA testing has a sensitivity/cut-off level of 50 ng/ml (in accordance to SAMHSA standards.)

Detection times for marijuana usage vary depending on the drug potency, tolerance, and health condition, fluid intake at time of test, method and frequency of marijuana use. It is usually not more than 15-20 days for chronic users and 3-5 days for occasional smokers. People who are overweight keep THC traces longer, as marijuana metabolites are fat soluble.

Note that if the initial 50 ng screen shows positive, then a gas chromatography test is used to verify, and that threshold is 15 ng/mg. So while another source claims a daily user is "hot" for 7 to 30 days at 50 ng, the same person might test positive for as long as 15 weeks at 15 ng.

Answer 2

First let me start by saying I am a 31 yr old male who is 5' 7" weighing 160 lbs with a fairly good metablolism and low body fat all of which are important factors in determining length of time that THC will remain detectable in urine since it is stored in your fat cells. Meaning, the heavier you are and less active you are the longer THC will remain detectable in your urine. I tested negative with my first urine of the day which will have the hightest concentration of THC in your urine after 18 days of abstinence... That being said, my usage consisted of 2-3 times per week... Again, everyone will be different in detection times given body type, height,weight, metablolism and most important fluid intake... If you have two weeks don't use eat high fiber diet, exercise, and up your fluid intake. Hope this helps. Also lets put to rest the myth that drinking tons of water helps cause it doesn't, it will only produce a dillute sample which some people consider a positive result!!!
