How Long Can Weed Stay in Your Body?

Whether you smoke a lot of marijuana or take only a few tokes, you can never know how long THC will stay in your system as the way it is processed is different for every person. It depends on how often you consume weed, your weight, stamina, and other health factors.

The truth of the matter is that THC (the psychoactive element of cannabis) is fat-soluble. If THC were water-soluble, all of its traces would disappear from our body in a few days. How long will it take marijuana to be completely gone from the body? That depends on a great variety of factors, such as the total amount of cannabis used over a period of time, the level of fat in the human body, diet, exercise patterns, and so on.

To find out the level of THC in the body, drug screenings usually measure the breakdown metabolite of cannabis known as carboxy-THC. The excretion of this metabolite is also affected by a number of factors including the person’s metabolic rate and even stress levels.

Even a break in weed use might not stop the increase of the THC level in the body. THC can sometimes reach its maximum several days after you stopped using marijuana.

The level of THC higher than 50 ng/mL in urine is considered a positive result, and any amount below 50 ng/mL is considered negative. It is impossible to predict what THC amount would result in a 50 ng level.

There is no certainty in measuring how long THC metabolites will be detected in your system after a crazy party or what THC levels for regular marijuana users might be.

As you can see, there is no clear way to find out how quickly THC will be gone from your urine or blood. According to a recent study, THC can stay in the body for up to 100 days after weed consumption. So hang tight, as it could take even more than three months for the evidence of cannabis use to be cleared from your body.
