After cannabis use, the amount of time that the drug remains in an individual’s body varies. Within a few hours of cannabis consumption, metabolites can be detected in a person’s urine. The presence of cannabis metabolites can continue to be detected up to a few days after a single dose of THC, or up to 30 days or longer following heavy usage.
