CBD (cannabidiol) has grown in popularity over the past couple of years. Many people have come to realize the wonderful benefits CBD can provide, however, some are concerned about drug tests or screenings because there can be trace amounts of THC that could be detected. In fact, an article published by The New York Times points to research that indicates drug tests can’t tell the difference between CBD and THC.
There isn’t a straightforward answer for how long CBD stays in our system, however, we will discuss some factors that are of influence.
Physical factors that can influence how long CBD stays in our system include genetics, metabolism, age and weight. Our BMI (body mass index) influences how quickly CBD is metabolized because CBD is stored in our fat cells. The higher your BMI, the longer CBD remains in your body.
How you consume CBD effects how long it remains in your system. For example, smoking dried flowers allows CBD to enter your bloodstream within seconds. On the other hand, an edible takes longer. Popular methods of CBD include: oils, vape, supplements, edibles, topicals, and dried flowers.
Frequency of Use
It’s important to remember that CBD does accumulate in the body. People who use CBD occasionally will experience a faster elimination compared to regular users, who will have CBD in the body for longer.
Urine tests are the most popular method of drug screening. “THC metabolites can be detected for as long as 15 days post-administration among frequent and daily users. However, the research also suggests that these numbers can vary based on the dosage.”
Remember that although you might not feel the effects of CBD, doesn’t mean it’s no longer detectable. The half-life of CBD is about 18 to 32 hours, however, it can be detectable for much longer than 32 hours.
This study found that the half-life of CBD that is orally-ingested is about 1 to 2 days, which means it could take up to 4 days for the CBD to completely leave your system.
Topical CBD or CBD that is ingested has a longer onset time, compared to smoking, vaping, or sublingual application of CBD that have the quickest onset time. It’s often recommended to take CBD oil with foods that contain fat, for better absorption. However, remember that there is a lot of factors that can determine how long CBD remains in your body: your BMI, the frequency of use, the way you consume CBD, etc.
