Marijuana is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant (Cannabis sativa). Cannabis is a term that refers to marijuana and other drugs made from the same plant. Other forms of cannabis include sinsemilla, hashish, and hash oil. All forms of cannabis are mind-altering (psychoactive) drugs. The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol).

“How long does marijuana stay in your system?” This question is asked by many different people, and for good reason. Marijuana (pot, herb, weed, grass) is the most commonly used and tested for drug in the United States and several other countries as well. Marijuana’s effects on the user and detection time depend on its strength or potency, which is related to the amount of THC (Tetrahydrocannabinol) it contains.

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.

The speed at which marijuana leaves your body depends both on the speed of your metabolism, as well as on the half-life of THC. It’s estimated that THC can have a half-life that ranges anywhere from 1-10 days. It’s almost impossible to find out what that half life is, which means that it is very difficult to use it to calculate how long it will take for all of the THC to leave your body.

The most common period of time is anywhere from 3-30 days, depending on your metabolism and the amount of marijuana that you’ve smoked. This is unfortunate, since it means that while most drug tests can only turn up evidence of other drugs if you’ve been taking the drug within a few days of the drug test, marijuana could still be detected in a urine test up to a month after the last time it is used. If you smoke it occasionally it will remain in your system for up to 10 days. If you smoke marijuana on a regular basis it will stay in your system for as long as 45 days, and if you smoke marijuana at a constant pace, it can stay in the body for 90 days, Marijuana is fat soluble. It stores in the fat cells of the body, the brain, the liver, and the kidneys, in other words the major organs.

Instead of spending your time trying to calculate how long marijuana will stay in your system, simply find out what kind of drug test you will be taking, and then purchase the product which is most effective and appropriate for the particular drug test you will be undergoing. There are many products available on the Internet, and you will be able to find one that fits your needs and budget. Whether you will be taking a urine test or a hair follicle test, remember that it is much safer to invest in an effective and appropriate product instead of attempting to pass your test by estimating how long marijuana will stay in your system.
