How Long Does Marijuana Stay in Your System?

Wondering how long does marijuana stay in your system? This article will help you understand the effects of MJ and how long it takes for them to wear off. Furthermore, how long does it take to flush it out of our system?

First of all, you need to understand that the answer isn’t as simple as a few hours, days, or weeks. In fact, there are many factors you need to consider when calculating how long marijuana stays in your system, so let’s explore them. 

How Long Does Marijuana Stay in Your System: Frequency of Consumption

When we consume weed, we will inevitably feel a buzz. Obviously, the intensity of said buzz will depend on how much marijuana we took, and how much THC it contains. 

After a while, the buzz will wear off, and we’ll feel back to normal again. Does that mean once the buzz is gone, so is any trace of MJ in our system? Unfortunately, no. 

Unlike (for example) alcohol, marijuana remains detectable in our blood and urine well after we no longer feel buzzed. When it comes to MJ, here’s what you need to consider:

  • If you’re not a regular marijuana consumer then it should take approximately 4 to 8 days for it to disappear from your system.
  • For more frequent consumers, it could take anywhere from 11 to 48 days for it to exit your system.
  • If you’re a daily consumer, it could take up to 70 days from your last consumption. 

However, that’s not all, as there are a few exemptions you need to consider:

  • Sometimes chronic consumers may have a higher tolerance to marijuana than anticipated, which means it can leave their system quicker than expected. 
  • Not all drug tests are the same, meaning they can show different results each time. Namely, the upper detection limit of home tests is often higher compared to lab testing kits.

Also, keep in mind that even though drug tests aren’t 100% error-free, the bottom line is that if you have any trace of marijuana in your system, it’s going to show up on the test. Furthermore, it’s now impossible to claim you got a false positive because you took some over-the-counter medication such as Motrin, Advil, or Nuprin.

How Long Does Marijuana Stay in Your System: Other Variables

Besides the frequency of consumption, there are also some variables we need to consider that play a huge role in how long MJ is detectable. These include:

  • Body fat/weight 
  • Fluid intake
  • Metabolism

Body Fat/Weight

You may be wondering what your weight has to do with how long MJ stays in your system. It’s simple: THC is fat-soluble. That means it can remain in your fat cells for weeks and even months at a time!

Ultimately, drug tests don’t detect THC, but rather a non-intoxicating metabolite known as THC-COOH. This metabolite lingers in our bodies for days/weeks/months and stores itself in our fat cells. Unless we burn the fat where the THC-COOH is stored, the metabolite will be detectable for quite some time.

In short, the more body fat we have, the longer marijuana will stay in our system and vice-versa.  

Fluid Intake

Water flushes out marijuana, it’s as simple as that. So, the more water you drink, the faster you’ll flush it out, especially before you take a drug test. 


Just like people with a low body fat percentage, if you have a fast metabolism you will excrete marijuana (or rather THC) faster than people with a slow metabolism. Unfortunately, there’s not much you can do to quicken your metabolism except eat smaller portions 4-5 times a day (containing healthy food) and keep active.

The Conclusion

As you can see, there is no definite answer to the question of how long does marijuana stay in your system? However, there are some ways you can figure out how long before a drug test you’re allowed to consume weed. 

Ultimately, the important thing is to never overdo your consumption, and pay close attention to the amount of THC it contains. Marijuana may not be harmful to your system, but you should always consume it with care and also know when not to indulge in it
