How Long Does Marijuana Stay in Your System?

Urine Tests

These are the most common. The time of detection is longer than one of saliva and factors like weight, body fat, amount of marijuana and how often it was used are related to how long the THC will remain in your urine. Regardless of fat or body mass, these are the data: if you have consumed once in life, the test will give positive between 1-6 days after consuming.

An infrequent smoker, 1 or 2 times a month, will be positive for 7-13 days after consuming. A frequent user, several times a week, may take 2 weeks or more to remove all MARIJUANA. And for the smokers, several times a day, every day, the maximum obtained to date, between 45-90 days for their total disappearance.

These would act similar to when we drink a lot of water, thus diluting the urine. If the urine is very dilute the laboratory will reject it because it is incapable of analyzing it correctly, which will cause the test to be repeated, and which will serve you if all you wanted was to gain some time.

Saliva Tests

These are much less common than urine and will only turn positive about 12 hours after your last draft, so they are much easier to pass than urine.

Hair Testing

The marijuana only stays in the hair a week after its last draft, so waiting about 8-9 days will suffice. This test presents a failure and is because sometimes the marijuana remains attached to the hair follicles. And in case of adhering, it could not be said that it has been consumed, since this effect could also occur in environments where the smoke contains TUCA.

Blood Test

These are almost always used by the authorities, as they must determine the amount of active marijuana in the bloodstream. Smoking provides the fastest way to absorb. In just 9 minutes the body gets the maximum levels of marijuana. However, 15 minutes later the THC in blood is reduced considerably, falling to significantly lower levels within the next two hours.

With a small dose, between 3 and 12 hours after smoking the THC would no longer be detectable. If the dose is higher, we would talk between 6 and 27 hours. These data are only for people who do not smoke regularly.

THC When Eating

Here the case changes a little, and the effects of the THC are not noticed until several hours after eating. Here blood THC levels would remain detectable up to 25 hours after consuming and THC metabolites about 50 hours to fall below detectable levels.
