In the case of marijuana, they are looking for the THC metabolite, THC-COOH. To figure out if you are âcleanâ for a drug test, you need to be able to determine the amount of THC metabolites in your system, as well as the testing levels for your drug screen. The half-life of THC metabolites is 7 days. Meaning every 7 days, the amount in your body will decrease by 50%. With this number in mind, most people can assume their body will be clean of THC metabolites within 3-4 weeks -- more or less depending on frequency, body weight and amount consumed.
