Tetrahydrocannabinol or THC can stay in a persons system from 2 to up to 90 days depending on several variables such as height, weight, physical fitness and substance usage. Occasional users would be clean within one week, a daily user can take up to one month, and a constant user can take up to almost 3 months.
According to the website of Columbia University's Health Services:
Marijuana itself does not "stay" in your system, but the main chemical in marijuana, THC, does. In fact, it may stay in your system forever because it is stored in fatty tissues of various organs.
Despite being stored in body fat, THC is onlydetectable for a certain amount of time. There are many variables that determine how long THC will remain detectable in your system, including amount used, frequency, metabolism, and the concentration of the plant. Many drug tests, including urine tests, look for 9-carboxy-THC which is the by-product of your body metabolizing the THC in your fat.
Marijuana Detection Times:
Frequent users blood drug test (defined as someone who smokes several times per week)
THC: 4-8 hours after smoking.
THC by-product: 2 or more weeks after smoking.
Frequent users urine drug test
THC by-product: 2 weeks to a month after smoking (3 months for extremely heavy users)
Infrequent users blood drug test
THC: 3-4 hours after smoking
THC by-product: 2-3 days after smoking.
Infrequent users urine drug test
THC by-product: up to 10 days after smoking.
