How long does marijuana take to leave your system?

how long does marijuana stay in your blood stream?

When you ask the question “How long does marijuana stay in your system?” you need to take into account the fact that there is no simple answer to this question. THC (Tetrahydrocannabinol) can stay in a person's body for as long as 3 to 90 days after smoking or being ingested orally. There are numerous determining factors for how long drug toxins stay in a persons body which vary from person to person, such as the analytical method used, your health, your body weight, metabolism, fluid intake, the type of drug toxin, and the degree of exposure to the drug toxin.

Dear badasschictatts22,
Because THC is stored and accumulates in body fat it is hard to predict the time it takes to leave the body. If you are a daily smoker of course it is much longer. anywhere from 2-40 days is the rule of thumb. So called flushing does not work because it is stored in the fat cells. Some flush methods have proven to be dangerous and have cause some deaths. If you are looking to pass a drug test you would have to stop smoking all together.
Sue...good luck
