One of the first things you need to know when starting CBD oil is how long it’s going to last.

Over the last several years, CBD oil has rapidly grown in popularity as a treatment for several tough conditions. Research shows that not only is it an effective treatment for nausea and sleep problems, but it can also be useful in treating chronic pain and stiffness.

CBD oil has been a total game-changer for those dealing with seizures, and it’s even become widely used as an alternative treatment for stress.

But many people still wonder precisely how long the effects of CBD is going to last, as well as how long it’s going to stay in their system. Of course, there is no easy answer.

It depends on several important factors, primarily your background, dosage, and method of consumption. As such, the only way to know for sure is to pay attention to your body. But let’s go over the basics to provide you with a solid foundation.

How Long Does It Take To Start Working?

Experts say that CBD generally takes about 30 minutes to start taking effect. As with anything else, one of the most significant factors on this is your personal biology. That said, the other primary factor on how long CBD takes to start working is how you choose to ingest it.

Vaping CBD oil or placing it directly under your tongue, are said to have the fastest impact times, as they both bypasses the liver altogether. Vaping allows CBD to be absorbed into the bloodstream via the lungs, but edibles require digestion to take place first.

The result is it may take up to an hour to feel the effects of edibles, especially if eaten with a meal. If you take it on an empty stomach, you may feel the impact a bit quicker, but the effects will most certainly be lower quality and not last as long. So most experts agree taking your CBD with a meal is best, to help absorption.

How Long Does CBD Last?

The very basic answer is that for most people, the effects of CBD oil can be felt for between four and six hours. However, this number can vary greatly depending on how much CBD you take, with stronger doses typically resulting in more prolonged effects.

It’s always important to consult your doctor before deciding on a CBD oil regimen, but for most people, a dose in the morning and one at night tends to be adequate. This is especially true for people dealing with chronic conditions such as anxiety, pain, or stiffness.

Another major factor in the duration of CBD oil is how you decide to take it. As you can imagine, CBD oil is an extremely versatile drug which can be put into just about anything. Many people like edibles, while others prefer vaping or the ease of droplets.

Each of these methods will have an effect on how your body processes the CBD. For example, edibles tend to take longer, but the effects generally last longer than faster methods such as vaping.

Like most parts of taking CBD, the perfect regimen is going to depend most heavily on you. There are pros and cons to each method, so it’s up to you to decide. The best thing you can do is talk to your doctor and listen to your body.

Tracking changes is almost always the best way to nail down the precise duration of CBD in your system.

How Long Does CBD Stay In Your System?

While CBD made from Hemp is legal across the country, many people still ask us how long CBD will stay in your system.

There hasn’t been a whole lot of research into this question, but one study has provided some key insights. The team tracked 14 patients with Huntington’s Disease who were given very high doses of CBD (around 700/mg a day) over six weeks.

The researchers found the blood plasma level of CBD in test subjects was at nearly undetectable levels, even just one week after the trial wrapped up.

They estimated around half the CBD in your system is filtered out every two to five days, depending on your biology. It’s also worth noting the researchers made it very clear that even after six weeks of high doses of CBD, no THC was detected in any subjects.


Just like most things with CBD oil, a lot of understanding how long it’s going to last comes down to you personally. If you’re taller, it may not last as long as your sibling who’s a lot shorter. But things aren’t always that clear cut either.

Be sure to check with your doctor before starting on any regimen of CBD, especially if you’re already on any medications. That said, the only way to understand precisely how long CBD oil lasts for you is to experiment.

So try different types of CBD, and at different strengths, until you find the perfect balance for you and your needs.
