How Long Does It Take to Detox From THC

THC is the active chemical component of marijuana; it gives the euphoric high feeling in smokers. Employers, especially those with drug policies, may have you take a drug test every once in a while. Drug tests come in many forms: saliva, blood, hair, and urine samples.

If a person consumed a single use of marijuana, THC can stay for 12 to 24 hours after use in the saliva. This means that it is detectable for one to two days. It is detectable within one to three days after use in the urine, one to three days after use in the blood, and three to five days after use in the hair. You can use this time frames to adjust your drug test. However, keep in mind that the length of time drug metabolites stay in a person’s system depends on his body.

THC is a fat-soluble chemical. This means that to detox from it includes considering the following factors: metabolism, body fat, frequency of usage, lifestyle, and potency.


Metabolism influences how fast THC metabolites is broken down and released from the body. A person’s rate of metabolism depends on his gender, age, sex, physical activity, and genetics. While gender, age, sex, and genetics are out of everybody’s control, the level of physical activity can be increased. Thus, making THC leave the person’s system faster.

Body Fat

Consider the fact that THC is stored and concentrated in fatty organs like the brain and reproductive organs. It is also stored in body fats up to a month after use. Therefore, the amount of body fat contributes greatly to the speed of detoxifying the body from THC.

Frequency of Usage

THC is stored in body fats for up to a month, as stated previously. Therefore, frequent usage can lead to the building up of THC metabolites. Thus, even if you stop smoking weed for a month after excessive use, it is not guaranteed that you will pass your drug test.


Regular exercise, healthy diet, and intake of diuretics helps in faster detoxification from THC. However, some studies show that if you work out the day after smoking weed, the THC level in your blood increases.


The stronger weed you take, the longer it stays in your system.
