How long should it take to get marijuana out of your system?

Trying to figure out how long marijuana can stay in your system is an important step when preparing for a drug test. No one wants to get caught with a positive result, and understanding how long weed stays in the body can help you plan accordingly. While there are numerous factors that influence how long it takes for marijuana to get out of your system, this article will provide an overview of how long does weed stay in your body.

How long does THC remain detectable on a drug test?

The length of time that cannabis remains detectable depends on the type of drug test used. Most urine tests can detect THC metabolites up to 30 days after use, while blood tests can detect traces of THC within 2-7 days after use. Hair follicle tests have the longest detection window, as THC metabolites can be present up to 90 days after the last use.

Factors that affect how long marijuana stays in your system

There are several factors that affect how quickly cannabis is cleared from the body, including

  • Frequency of use:

In general, regular users tend to retain more THC than infrequent smokers because their bodies have less time to clear it from their system between sessions.

  • Metabolism:

People with faster metabolisms tend to eliminate cannabinoids more quickly than those with slower metabolisms.

  • Body fat percentage:

THC is fat-soluble and tends to accumulate in fatty tissue throughout the body, so people with a higher percentage of body fat retain more cannabinoids than those with a lower percentage.

Types of drug tests used to detect cannabis use

Urine test:

Urine testing is usually the most common form of drug testing used by employers and medical professionals alike because it’s relatively cheap and easy to administer. As mentioned above, most urine tests have a detection window of 7-30 days post-use, depending on the frequency of use and other individual factors such as metabolism or body fat percentage – although some extended panels can detect up to 90 days back.

Saliva test:

Saliva testing has become increasingly popular in recent years, largely due to its convenience and shorter detection window (typically only 1-3 days). It’s rare for employers or medical professionals to administer saliva tests, but they are a good alternative if someone needs quick results before taking a more comprehensive test such as a hair follicle screening or urine sample.

Hair follicle testing:

Hair follicle testing is generally considered to be the most accurate method for detecting cannabis use, as its detection window extends up to 90 days after use; however, this type of testing is also much more expensive than other methods, so it is not commonly used outside of legal proceedings or clinical settings.

Can you speed up the process of getting weed out of your system?

While there is no surefire way to speed up the process of completely ridding yourself of cannabis from your system ahead of time, there are several steps you can take that may help reduce retention levels prior to drug screening such as drinking plenty of hydrating water or exercising regularly will burn fat cells where cannabinoids tend to accumulate – which could potentially reduce chances of producing a false positive result during the testing procedure. In addition, limiting the intake of non-essential foods high in sugar such as soda and sweets will help increase the metabolic rate allowing for faster clearance of all substances including weed.


It’s important to understand just how long weed stays in your system in order to adequately prepare for any upcoming drug screenings. With an average half-life of around 24 hours, the majority of users should clear their systems anywhere within a couple of weeks depending on their usage habits and frequency of administration. However, certain individuals may find themselves facing longer detoxification windows, especially if they have been using heavily for extended periods of time.
