Cannabidiol is rising to stardom, thanks to its numerous medical benefits. Better known as CBD, it is one of the more than 100 chemical compounds called cannabinoids, which are found in the cannabis or marijuana plant.

Each time people hear the word “marijuana,” they easily associate it with getting “high.” Actually, tetrahydrocannabinol (THC) is the main psychoactive cannabinoid found in cannabis, and this is what gives you the “high” feeling. Unlike THC, CBD will not get you “high.” That being said, this makes CBD a better choice for those looking for relief from pain and other conditions.

The market for CBD oil is fast growing. CBD oil is made by extracting CBD from the cannabis plant and then diluting it with a carrier oil such as coconut or hemp seed oil. Several studies have found that CBD oil is effective in alleviating pain, reducing anxiety and depression as well as treating neurodegenerative and cardiac problems to name a few.

You have all heard about the miraculous works of CBD oil, so the next question you would probably want to be answered is how soon does CBD oil work in the body?

Just like any other supplements or drugs, there are several factors that influence how long CBD takes to work after being ingested. For instance, the concentration and dosage of CBD and your weight and metabolic rate actually matter. But perhaps, it is the route or method of use that is the biggest determinant.

CBD can be ingested in several different ways. You can have it inhaled via vaping, taken orally, absorbed sublingually, and applied topically. It is vital that you understand how each method works as it affects how much CBD reaches into the bloodstream and how quickly it will get there.

Bioavailability is the degree and rate a substance reaches the bloodstream after absorption. The general rule of the thumb is that the less digestive process it goes through, the less time it will take to reach the bloodstream.

Intravenous administration

Direct intravenous administration is the fastest and most direct route to get the most bioavailability of your CBD. It delivers 100% CBD into the body, but not a lot of people are actually using it.


Inhaling CBD through vape additives or vape juices is the second fastest and recommended route of delivery. Vaping allows CBD to directly enter into the bloodstream via the lungs. According to several reports, this method has a bioavailability rate of up to 46%. While it is a case-to-case basis, some people reported experiencing relief between 5 and 10 minutes following vaping.

Sublingual method

Sublingual intake of CBD oil is another fast means of delivering CBD into the body. Placing CBD oil under the tongue allows it to be absorbed by a vein called the sublingual gland. It is then directly absorbed into the bloodstream, bypassing the digestive system and liver.

The reported bioavailability rate of sublingual administration ranged between 12% and 35%. CBD products for ublingual consumption includes CBD sprays, CBD tinctures, and CBD lozenges.

Oral administration

CBD products for oral consumption including capsules, edibles, and beverage. This is the most common way to consume CBD. However, its reported bioavailability rate is quite slow at only 4%. This is because the substance needs to pass through the digestive systems, which filter a large chunk of the CBD and significantly reducing its bioavailability.

At the end of the day, each person is unique. We have our own bodies, systems, and behaviors. That being said, there is no universal answer to the question of how long does it take CBD to work. Do a little experimentation and see what will suit your needs best.
