Some THC metabolites have a half-life of 20 hours, while others like THC-COOH have a half-life of 13 days, according to High Times. A 2014 study found that regular marijuana users have traces of marijuana in their urine for about two weeks, according to High Times.
For frequent or heavy marijuana users, their urine tests may show up positive for up to 100 days after their last use, and blood tests will show the presence of THC for up to one week. THC-COOH builds up in the body each time marijuana is used, and thus takes even more time to decline, according to Norml.
