More research is needed to pinpoint exactly how long it takes CBD oil to exit the body, but early studies offer some insight.
Whether you’re using CBD oil supplements to augment your athletic training regimen or simply to naturally promote wellness, you’re likely curious as to how long the product and its compounds stay within your system to encourage balance. The answer may impact how you schedule your CBD servings, and whether you opt to take CBD supplements once, twice, or more times every day.
While the question is simple and straightforward, the answer to how long CBD oil stays in your system is a bit more complex.
There’s no universal answer as to how long it takes for CBD to be eliminated from the system, as scientists still need to learn more. Additionally, there are various factors that influence the process’ rate.
Where Does CBD Go?
When you consume CBD oil, CBD levels in your bloodstream temporarily rise. Your blood carries CBD throughout your body, where the compounds interact with cannabinoid receptors to stimulate the endocannabinoid system.
Like all cannabinoids, CBD and its metabolic byproducts are lipid-soluble. This means they accumulate in fat reserves of your body before being slowly released over time. Eventually, the metabolites are eliminated from the body through feces and urine.
CBD Detectable In Your Systems
It is unfortunately hard to say exactly how long CBD oil and its compounds stay in your system. However, while research is limited, findings in a handful of studies provide some insight into how long CBD can stay around in our systems.
In a 1991 study published in Pharmacology Biochemistry and Behavior Journal, participants were given extremely large servings of CBD for six weeks. Once CBD servings were discontinued, some CBD was still detected in their systems up through one week later. The researchers estimated that the half-life of CBD (when half of the CBD was eliminated from the body) was two to five days. After a week’s time of having no servings, the levels of CBD were “virtually undetectable” in the participants’ bloodstreams.
In 2012, a research review published by Pharmaceuticals found the half-life of CBD to be between 18-33 hours when CBD was administered intravenously, 27-35 hours following the inhalation of CBD, and 2-5 days when the CBD was swallowed and ingested.
These findings suggest that even when taking extremely high serving sizes of CBD, you can reasonably estimate that the compounds will be out of your system after about one week.
Factors That Come Into Play
Another reason why there is no easy answer as to how long CBD oil stays in your system is that it varies from person to person and is impacted by genetics, lifestyle choices, and CBD oil consumption behaviors.
How long CBD stays in the system is influenced by an array of factors, some of which include:
- Your body weight and body fat percentage
- Your metabolism
- How much CBD oil you consumed
- The method you used to take CBD oil
- How frequently you take CBD oil
- How much water you drink
In general, those with higher levels of fat content will store cannabinoids like CBD more readily than those who are leaner. Your metabolic rate will also influence how quickly the compounds are digested and transported.
Additionally, your CBD oil consumptions habits, including frequency, serving size, and method of choice will directly influence how much CBD is delivered to your systems, which in turn will impact how long detectable levels of CBD stay in your system.
How Long CBD’s Effects Last
While hemp-derived CBD oil is non-intoxicating and will not get you high, regular users often say that shortly after taking the supplement they feel “in the flow,” with increased energy and greater focus. Others, however, say they feel that CBD oil provides a heightened feeling of relaxation and calm shortly after ingestion.
Some have said they don’t notice any effects directly after taking CBD oil, but that they experience an overall better feeling and greater performance in the day and improved sleep habits at night.
The balancing effects of CBD oil can vary from person-to-person. For those who notice awakening or relaxing effects, how quickly they arrive and how long they last will also vary depending on factors like your CBD serving size, how you take your CBD, and your body size.
The full effects of CBD may only remain for 4-12 hours, depending on method of use. Some prefer to take multiple servings of CBD oil throughout the day to better ensure a more constant level of cannabinoids in the body.
Whether or not you feel any of these effects after taking your CBD oil supplement, CBD will continue to interact with your body’s receptors to promote balance for as long as the compounds remain in your systems.
Drug Test and THC Considerations
In most cases, hemp-derived CBD oil will not be detected by a drug test. Federally legal in the United States, hemp CBD oil naturally contains only trace levels of tetrahydrocannabinol (THC), the intoxicating compound associated with marijuana that causes a high.
Most drug tests are designed to check for the presence of cannabis look specifically for THC or its main metabolite, 11-nor-delta9-caboxy-THC (THC-COOH), and not CBD.
Hemp contains no more than 0.3% THC by dry weight. This means that when consumed at suggested servings, in most cases hemp CBD oil won’t cause a positive test.
Keep in mind that some studies have shown that eating hemp foods and consuming hemp oils can, in rare cases, cause a positive test result in urine and blood tests. If you are concerned about having a positive drug test, it is recommended that you avoid consuming CBD oil until after talking with your healthcare, employer, or drug screening company.
