If you’re new to the world of CBD, you might want to know how long the substance will last in your system. As employees throughout all sorts of industries are encountering drug testing in the workplace, workers who face issues with pain, insomnia and anxiety may be reluctant to try CBD oil due to fear of failing a drug test. Despite the legalization of marijuana in Canada (and hemp-derived CBD products in the U.S.), there is still an unjust and negative stigma surrounding the cannabis plant. As such, a strict workplace may not tolerate the use of CBD oil.
In the most common workplace drug screen—a urine test—employers aren’t looking for CBD, because CBD has never been found to impair judgment or motor skills. Instead, workers fail workplace drug testing for marijuana’s main active ingredient, THC, which can exist in low amounts in some CBD products and then persist in the human body for weeks. (Leafly)
After ingestion, it may take up to 30 minutes for the CBD oil to take effect. Generally, CBD does not stay more than a week in your body and may take anywhere from 3-7 days to clear out. How long it stays in your system can depend on several factors, including:
As with most other substances, a higher dose results in a longer effect. If one person took a 70mg of CBD oil, while another took 1mg of the same substance, you would find that (unsurprisingly) the one with the higher dose would need more time to be free of CBD in their body.
Method of consumption
There are many different ways to administer CBD into your system. The method you choose determines the effect and how long it stays within your body. Different forms of CBD include oils, capsules, edibles, topicals, vapes and more. Taking CBD sublingually (under the tongue) or orally will be absorbed into the bloodstream faster and linger longer. CBD edibles, however, would require more time for absorption as it needs to be processed through the digestive system. With topicals such as lotions and creams, the CBD enters the system through the surface of the skin. As such, topicals should be applied generously to overcome the low cannabinoid absorption rate, with the effect peaking at about 90 minutes.
A person’s metabolism and weight may play a prominent role in how fast the CBD is absorbed and later excreted from the body. Everyone’s metabolism operates differently, determining how long it takes to break down and synthesize the cannabinoid. Furthermore, someone with a larger body mass will require more CBD in order to feel its effects. Another aspect is whether the CBD oil is taken with food, as an empty stomach causes the substance to be metabolized and eliminated at a faster rate.
Although CBD is an all-natural product that has been deemed “safe and well-tolerated” by the World Health Organization, you may want to be wary of its effects before a drug screening. No matter how pure or high quality, CBD oil can still contain trace amounts of THC which may create a false positive result on a drug test. Many employers do not consider CBD to be negative drug; however, if you’re concerned about any professional consequences due to CBD oil use, it may be a good idea to consult with an HR representative.
