Long story short, the more CBD you take, the longer the effects should last. However, there is no one-size-fits-all pattern for figuring out how long each person will experience them.
That being said, there have been a few studies that looked into the time CBD can stay in our bodies.
How Long Do the Effects of CBD Last?
Regardless of your motivation, we’d like to answer your question.
Research on cannabis has made tremendous progress since the past decade, but the truth is that we haven’t always had access to CBD oil that we know it today. Therefore, we still need more studies about the time CBD will last in one’s system. Experts in cannabis science don’t know it yet.
Here’s the Answer: We Don’t Know Precisely Yet
Did you look into the time your body needs to get rid of CBD? If there’s something you know, and we haven’t mentioned it here, let us know in the comment section! We’ll be updating this article every time new data comes out.
Sublingual delivery isn’t always a better option for all substances, points out Dr. Birdsall—some B vitamins, for instance, need to be “activated” by the liver in order to do their jobs—but for certain vitamins and medications, it can be a super effective delivery method.
Even so, Kater says that “most of the literature supports the notion that CBD has better bioavailability when consumed sublingually versus orally. [and] MCT oil-based tinctures are thought to provide better uptake than a traditional oil.” But, again, there’s no evidence that this applies to the exact CBD oil or tincture that you, specifically, have in your cabinet. As mentioned before, every formulation is different, and those small differences matter when it comes to bioavailabilty.
To find out—because there’s been relatively little rigorous research on CBD to date and I’m a skeptic by nature—I reached out to a doctor and a scientist for the 411. As I suspected, this isn’t a topic that has been studied in depth. Yet there is some reason to believe that certain CBD products may truly be more bioavailable when absorbed under the tongue than if taken through food or drink.
Long story short: You may as well try holding your CBD oil or tincture under your tongue before swallowing it—you could find that you feel it working slightly faster. Anecdotally, says Dr. Birdsall, experts recommended that you hold it there for at least 60 seconds. (A word of warning: There will be drool.) Your other option is to try a product that’s specifically created to be absorbed sublingually, like Kin Slips, which are kind of like those breath-freshening films that dissolve in your mouth.
After all, if there’s one thing that can be said about the wild west of CBD, it’s that experimentation is key—whether you’re looking for your perfect dose or your perfect delivery method.
The ECS has receptors all across our skin, and if the CBD product can permeate through the skin via a transdermal application, it’s expected to have a higher bioavailability.
Before we dive in, let’s define how this happens within our body and what factors influence it.
Bottom Line and Summary
On the more positive side, it might be possible that using oral CBD may lead to a more balanced set of effects across time when compared to say vaping CBD.
While there isn’t a study examining the use of sublingual CBD oil or spray in humans outside of Sativex (a 50:50 CBD/THC medicine) we are aware of, it’s thought that sublingual bioavailability of CBD sits somewhere between CBD taken orally and when vaped (between 6% and 54%).
