You’ve undoubtedly heard of the medicinal relief that cannabidiol (CBD), a non-intoxicating compound found in the cannabis plant, can bring to chronic pain and anxiety disorders for different conditions. Although many people may benefit from using CBD, they still might be hesitant to try it because of the fear of failing a drug test or the general stigma that still surrounds cannabis in some regions. But, have you ever wondered how long does CBD stay in your system?

It may be confusing to understand the difference between cannabidiol (CBD) and THC, particularly because both derive from the same plant. Naturally, the main difference is that CBD does not have the same psychoactive effects as THC. This means that it can provide many of the same benefits in relieving pain, seizures, anxiety, nausea, and other symptoms associated with common medical conditions without making you feel “high.”

The metabolism of an individual plays a prominent role in how easily the CBD is metabolized and eventually excreted from the body. Another factor that may influence the effects of CBD is if it is taken with food or on an empty stomach, because certain foods may improve bioavailability and the overall concentration of CBD in the body.

How long does CBD stay in your systemy

CBD oil typically takes 20-30 minutes to have an effect after ingestion. Afterward, the time that will it take to leave your system will depend on some factors.

How long does CBD stay in your system depends on:

  • Serving scale
  • How you used CBD (vaporization, edibles, oil, tincture, etc.)
  • If you ate in advance
  • The weight of it

There is not much credible or authoritative research available at this time on CBD, so to calculate how long it can take for the CBD to leave your body is not an exact science. It could be between 1-2 days or, on even, 4-25 days based on available studies.

Despite having to rely on any hard evidence, you may want to be on the safe side before taking a drug test and conclude that CBD leaves the body at the same pace as THC. In the case of daily usage, a urine test (the most common way of testing) can detect THC metabolites up for 10-15 days. The numbers can vary depending on the amount and the level of use.

If you are worried about any professional implications resulting from using CBD oil, it can help to address the problem with an HR representative or review the relevant CBD laws of your state. Many employers don’t find CBD to be in the same league as marijuana, because it doesn’t cause any psychoactive effects that could affect your job.

In a 2016 study published in the “Journal of Pain”, participants were given different types of CBD-rich cannabis products, including oils, capsules, and herbs. The urine samples from all 15 subjects tested positive for CBD two hours after the administration. After the last day of treatment, researchers tracked one participant and noticed that after 24 hours CBD was no longer detectable in the urine.

Ingestion is the most common CBD-consumption process. Taking a few drops of CBD oil directly into the mouth is definitely a pleasant way to reap the advantages of this cannabinoid. However, ingestion is not always the most efficient form of intake for those who instantly want to experience the CBD effects.

Although oral ingestion of CBD has become popular for its ease of use, compared with inhalation or sublingual administration it is a very inefficient method of consuming. This happens because only about 5 percent of swallowed CBD ends up in the bloodstream, meaning poor bioavailability is given by this process.


The sublingual approach is seen as being more successful than ingestion. CBD oil can be ingested sublingually by inserting a few droplets under the tongue and holding it for two to four minutes, then using the tongue to rub it within the cheeks before swallowing the rest. Through this way, CBD is transmitted through the mucous membranes found in the mouth into the bloodstream, fully bypassing the digestive system and liver. Sublingual consumption results in greater bioavailability compared with oral intake.


Inhalation is also an important method of incorporating CBD because of its rapid absorption and lung capacity in moving CBD into the bloodstream (better bioavailability). The contact with the body stays the same when you are smoking a high-CBD strain or taking a draw from a CBD vape pen. The cannabinoids are sent directly to the lungs when CBD is inhaled, where they are quickly absorbed into the bloodstream and then placed into circulation.

Existing research indicates that within three minutes of inhalation, CBD reaches its peak in blood concentration, meaning the effects can be felt shortly after use. This approach is, therefore, desirable for those seeking urgent pain relief.


Topical CBD comes in many forms: infused in lotions, creams, salves, and other products for health and wellness. This can be applied directly to the skin, where it can be absorbed through the skin surface and interact with cannabinoid receptors found there. In some cases, subjects infused with CBD should be liberally applied to overcome the skin’s low cannabinoid absorption rate.

Please note that even CBD products derived from hemp legally contain up to 0.3 percent of THC. For certain CBD-curious customers who don’t want THC in their body or face to result on a false positive on a possible drug check, this may trigger hesitation. The odds of hemp-extracted CBD oil failing a drug check however are extremely low.
