How Long Does Marijuana Stay in Your System?


Missouri has legalized marijuana for both medicinal and recreational use! However, even though you don’t technically need your medical card to visit dispensaries, you should still renew it.


Medical marijuana card holders enjoy a variety of benefits including lower taxes and product costs, higher possession and purchase limits, and the ability to cultivate more marijuana plants at home.


Although marijuana is legal in Missouri, there are many positions that may require drug testing for employees. It is important to be aware of how long cannabis can stay in your system whether you are using it for medicinal or recreational purposes.


So how long does cannabis stay in a person’s system? The answer to this question is not definite, and it varies quite a bit from person to person. To understand how long cannabis can stay in our system, we also need to understand drug tests.


Types of Drug Tests

There are four main types of drug tests that are typically used, but the urine test is by far the most common. Urine tests are very popular because they are pretty non-invasive and cheap to administer.


Blood, hair, and saliva tests are rarely used due to issues with detection windows, and blood tests are more invasive and expensive.


How Long Does THC Stay in My System?

The amount of time THC takes to leave your system will depend on a number of factors, including:

  • What/when/how much you last ate

  • Gender/body fat

  • How much marijuana you consumed

  • Delivery method

It also depends on which type of drug test you take, because all drug tests have different detection windows. This means that while one test may detect cannabis for up to 90 days, another may only detect it for 48 hours.


How often you use marijuana also plays a huge role in how long THC stays in your system. If you are a frequent or heavy user, THC will stay in your system for much longer than a person who uses cannabis infrequently.


Urine Test Detection Windows

As previously mentioned, how long THC stays in your body depends on how frequently you use cannabis. However, we have some rough estimates on how long urine tests can detect THC in the body.


Urine tests can detect marijuana for anywhere between 3-30 days after last use. Whether it’s 3 days or 30 will depend on how often you use it and the other factors listed above.


The Bottom Line

The answer to the question of how long THC stays in the body is that it depends. It depends on the type of test you are taking, how frequently you use cannabis, your body fat percentage, and more.


Urine tests are most frequently used, and they can show marijuana use anywhere from 3-30 days after a person last uses it.
