How long does cannabis stay in the body system?

Cannabis can be detected with a urinalysis up to an average of 27 days in the body for the average user, as reported by a paper recently published by the National Center for Biotechnology Information. Each individual's metabolism processes and breaks down cannabis at different rates making it hard to provide a definite answer.

Chronic cannabis users will find that the cannabis can stay in their system for an even longer period of time with reports of the compound being detected in the body even after 77 days. Those who rarely smoke marijuana may find that cannabis may be metabolized from the body in only several days.
