How Long Does Marijuana Stay in Your System?

Medical marijuana is legal in the State of Virginia, and thousands of patients are already reaping the benefits. If you don’t already have your medical marijuana card, give us a call! We can help!

Some medical marijuana patients may have to undergo drug tests at work and might be curious about how long cannabis stays in their system. This is a valid question, and the answer varies quite a bit depending on different factors.

Marijuana is still a drug, so it is very important for users to understand the effects it can have on mind and body. Understanding how drug tests work is also critical for cannabis patients to be aware of how drug tests work.

Different Types of Drug Tests

When a person uses a substance, trace amounts of it will remain in the body, which can be picked up by using any of these test methods. However, drug tests are not without issues.

False positives are possible because other substances or even foods can trigger positive results including poppy seeds, hemp, and even ibuprofen.

There are four main types of drug tests, though one of them makes up for a high percentage of all employer drug test methods: urine. The other types include saliva, hair, and blood tests. Urine tests are the most popular because they are quick, easy, and non-invasive.

How Long Will THC Stay in My System?

There is no definite answer to this question because it will vary depending on many factors, including, but not limited to:

  • What/when/how much you last ate

  • Body weight/gender

  • How much marijuana you consumed

  • Delivery method

Depending on what type of drug test you take, THC can stay in your system anywhere from 3-90 days. The only tests that can detect THC for up to 90 days are hair tests, which are rarely ever used.

If you use cannabis daily or relatively frequently, the THC will remain in your body for longer than someone who rarely uses it. Heavy users may test positive for a while after they last use cannabis.

A casual user will use cannabis less than twice a week, a frequent user may use it multiple times a week, and heavy users consume cannabis daily or multiple times per day.

Blood Tests

Blood tests are a bit different than the other types of drug tests due to their small detection window. They are also invasive and more expensive to administer than a urine or saliva drug test.

Here is a general window for THC detection through blood tests:

  • Casual users: 1-2 days

  • Frequent users: 1-2 days

  • Heavy users: up to 7 days

Get Your Medical Marijuana Card in Virginia

Recreational marijuana may be legal in Virginia, but it does not mean much if there are no recreational dispensaries for people to purchase products from. Until then, adults may grow their own.

There is no telling how long it will take for recreational dispensaries to open their doors, but we would assume it will be at least a year. So, if you would like to visit a medical dispensary until then, you will need your medical card.

In order to qualify for your medical marijuana card, you will need to have a condition that would make you eligible. If you aren’t sure if you would qualify, give us a call and we can answer any questions you may have about the process.

If you don’t already have yours, no worries. We can help!
