How long does Marijuana stay in your system?

After smoking weed or consuming supplied from marijuana dispensaries, it through edibles, cannabinoids are absorbed into the bloodstream and carried throughout the body. It is broken down into metabolites that can be detected in urine, blood, and saliva samples.

The primary active cannabinoid in marijuana is THC (delta-9-tetrahydrocannabinol) which has a half-life of about two days. However, it peaks in the body at three hours and can be detected for 12 weeks through urine testing.

Urine tests are most reliable and indicate the most extended time that marijuana can be detected in the body. It can be seen for days or weeks, depending on frequency and dosage.

Marijuana blood tests

Marijuana cannot be reliably detected in blood tests. Some studies claim trace amounts could even show up as long as a month after use, but other studies found no detectible THC after 3-4 days. It is thought that THC metabolites are not fat-soluble and so cannot be stored in the body like other drugs, which means they do not show up in blood tests.

However, there is some exception because of individual factors such as the rate of metabolism. While it may be impossible to detect minimal amounts in the bloodstream around the 3-4 day mark, there is a chance it could be seen in blood tests for longer.

  • Saliva tests

Marijuana use can be detected up to 24 hours after ingestion through saliva testing. Detection time tends to increase with increased dosage and frequency of use. One study found that heavy users can test positive greater than one week after last use, whereas infrequent users may test negative within 36 hours.

  • Marijuana urine testing

In recent years, companies have been developing new technologies to test for marijuana use. These devices are similar to home pregnancy tests and work by detecting metabolites of THC.

There are two classifications of metabolites that can show up on a urine test: THC-COOH and 11-nor-delta9-carboxy-THC. Urine tests look for both metabolites but also have cut-off levels, so some may not be detected, especially in infrequent users.

The first metabolite – THC-COOH – is secreted in the urine as an inactive metabolite and can remain detectable for days or weeks.

The second metabolite is excreted within hours of consumption and usually does not appear above 50 ng/mL.
