How long does CBD stay in your system?

One of the most questions asked is, how long does CBD stay in your system?

Maybe your facing a drugs test at work or just want to know in general, whatever the reason, you will find all you need to know about how long CBD stays in your system.


There are many species of the cannabis plant. All cannabis plants have a unique chemical makeup, but sometimes they can share similar compounds, albeit in different concentration.

Some of the species can have a chemical compound called THC (Tetrahydrocannabinol). THC is the one responsible for making you high. Marijuana is one of those species of cannabis that is high on THC. On the other hand, CBD doesn’t make you high, as CBD effects are only therapeutic and even at its highest dosage, therapeutic and soothing. It is predominantly found in the hemp plant that belongs to cannabis plant family. It is popular for not making you high.


How long will CBD stay in your system?

With CBD becoming more out there on the scene so dramatically in the recent years, its very understandable that many people want to know how long it stays in your system. However, it is a difficult question to answer.

Despite these limitations, we can make an educated guess based on the evidence that is available. Like this study from 1991, which looked at 14 subjects with Huntington's disease who took high doses of CBD for six weeks.

After consuming about 700mg per day during this time period, the study found that just one week after they stopped dosing, CBD levels in subjects blood averaged just 1.5 ng/ml. After one week, CBD was “virtually undetectable”.

The study also stated that the estimated half-life of CBD was 3-5 days and that there were no significant differences between genders. From this, we can ascertain that, for most people, CBD will completely leave their blood after just one week.

There are no studies on how long CBD remains detectable in your urine, hair or saliva. However, your saliva usually offers evidence of pharmaceutical use for a couple of hours to one day.

When it comes to hair, however, it’s a different story. This is because your hair can keep a pharmacological record of what you have consumed during your entire life. Even if you cut the hair on your head, your body hair will still preserve this information. However, most hair tests will only look at the last inch-and-a-half of your hair, which represent about the last 90 days of your life.

CBD and Drug tests.

Drug tests are mostly used now essentially look for THC metabolites that can be found in the system. So, if you have had marijuana in the past three months, it is possible that you will be found to have THC in your body. But this does not answer the question of, how long does CBD stay in your system.  

Not all CBD infused products (even oil) are not purely all CBD. They might include some companion compounds that came along for the ride during CBD’s extraction. One of these can be THC (legally, CBD products are allowed to have 0.3% THC.)

 Although the THC concentrations in any reputable CBD oil are nowhere near high enough to cause you to test positive in a drug screening.

This is why it is so important that choose a product from a reliable and trusted company, like ourselves


How long does THC stay in your system?

Unfortunately, most forms of cannabis are still illegal in many parts of world. This is despite modern medical science revealing the countless health benefits that it offers. That’s right, it’s not just CBD that offers so much therapeutic value.

THC is proving to an important medicine in its own right, with research’s showing it to be a potent pain reliever, effective for treating nausea and could even help protect against brain injury.

But, Because of outdated laws and close-minded politicians, many are still prosecuted for THC. The is why being caught with weed or having weed in your body you will be charged.

Again, however, the answer is not at all straightforward and clear-cut. Not only does THC get processed through the body at different speeds depending on numerous factors, there are also many ways of testing for it. While the most common test analyses urine samples, blood, saliva, and hair can also be tested for signs of THC use.

Here’s a brief overview of how long THC remains detectable with regards to each of the most common drug tests. These answers depend on how much and how often you consume THC.

  • Blood - Between 3 and 30 days
  • Urine - Between 2 and 100 days
  • Saliva - Between 12 and 24 hours
  • Hair - Theoretically, as long as you have been alive. However, most hair tests will only look at the last 90 days.
