How long does marijuana stay in your system?

This question is asked by many different people, and for good reason. Marijuana is the most commonly used and tested for drug in the United States and several other countries as well. Marijuana is also the drug that is more likely to stay in your system for days, weeks, or even an entire month after the last time that you smoke.

Therefore, even though marijuana is one of the least harmful drugs out there, it is also the most likely drug to cause you to fail a drug test.

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. Quite simply, it’s argued both that THC never leaves your brain, as well as that there are several different factors which can affect whether or not you test positive for marijuana use.

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. Unlike most other substances, the half-life of THC can vary quite a bit, depending on who is using it, when it’s used, and several other factors. For example, 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.

Not only that, but your metabolism and how much marijuana you smoked will also have an effect on the length of time that it will take you before you can test without testing positive for marijuana use. After all, the half-life is only the length of time that it takes for you to lose half of the THC that is in your system. If you’ve smoked a lot of marijuana, then it will take you longer before the THC in your body drops back below the amount that is detectable by most drug tests.

For this reason, when you ask “How long does marijuana stay in your system?” you have to realize that it’s very unlikely that you’ll be able to get a usable answer. 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.

Marijuana

Marijuana is a green or gray mixture of dried, shredded flowers and leaves of the hemp plant (Cannabis sativa). It is the most often used illegal drug in this country. All forms of cannabis are mind-altering (psychoactive) drugs that contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana.

THC is the chemical in marijuana which makes you feel “high” (which means experiencing a change in mood and seeing or feeling things differently). Certain parts of the plant contain higher levels of THC. The flowers or “buds” have more THC than the stems or leaves.

When  marijuana is smoked, THC goes quickly into the blood through the lungs and then to the brain (this is when the “high” is felt and can happen within a few minutes and can last up to five hours). THC is absorbed more slowly into the blood when marijuana is eaten because it has to pass through the stomach and intestine and can take up to one hour to experience the “high” effects, which can last up to 12 hours. THC is absorbed quickly into body fat and is then released very slowly back into the blood. This process can take up to one month for a single dose of THC to fully leave the body.

Marijuana, the most often used illegal drug in this country, is a product of the hemp plant, Cannabis sativa. The main active chemical in marijuana, also present in other forms of cannabis, is THC (delta-9-tetrahydrocannabinol). Of the roughly 400 chemicals found in the cannabis plant, THC affects the brain the most.
