Is More CBD Better? The Science Behind CBD Dosing for Anxiety and Other Conditions

  • Recent studies suggest that increasing CBD dosages does not always guarantee relief or a positive bodily response in patients with certain chronic disorders like Epilepsy and Anxiety. Higher dosages simply target areas of the brain in addition to the treatment area.

In 2015, the National Institute of Health allotted $21.2 million of its $111 million cannabinoid research budget towards projects exploring the medicinal potential of these compounds. These projects proposed to manipulate the body’s endocannabinoid system, either by modifying endocannabinoids or with phytocannabinoids from the cannabis plant.

While the primary psychoactive phytocannabinoid, delta 9-THC, has acknowledged medicinal value, cannabidiol (CBD) is widely known for its broad range of potential medicinal uses. In recognition of CBD’s vast potential, over $9 million in grants were awarded in 2015 to fund CBD-specific medicinal research.

Much of this research has centered around the treatment of epilepsy, with studies showing that CBD has significant potential for treating the condition in children at high doses. A daily dose over 600 mg reduced seizure frequency by 39%. While this is a far greater amount than you’d find in many of the CBD consumables available at your local dispensary, many retail CBD products with lower levels of the cannabinoid are reported to be effective at treating anxiety, pain, and a host of other disorders, either through self-experimentation or anecdotal reports.

So why not crank up the CBD dose to reduce your anxiety? If a little is good, shouldn’t a lot be better? It turns out that for CBD, the answer is no; CBD’s medicinal efficacy might require a particular dose range. Call it a “Goldilocks Zone,” where there’s not too much CBD but not too little, either.

Intriguingly, this Goldilocks Zone differs for each disorder. For instance, CBD appears to treat anxiety at relatively low doses compared to the high doses used to treat epilepsy.

Overshooting the Goldilocks Zone when trying to treat a given condition may reduce the efficacy of CBD. An animal study published back in 1990 found that low to moderate CBD doses reduced anxiety, but CBD’s anti-anxiety effect disappeared at higher doses. Importantly, the authors note an inverted-U response to CBD. Out of the four doses tested, the lowest dose had a moderate anti-anxiety effect, the second-lowest dose had the greatest anti-anxiety effect, the third dose had a moderate effect, and the highest dose had no effect.

While it may sound out of the ordinary, this “inverted-U” effect is actually quite common among drugs that affect multiple brain receptors, as CBD does. In fact, 37% of published toxicology articles report some degree of an inverted-U response, indicating that this is not a random event but instead reflects differential drug effects on brain targets.

Different doses of CBD may actually be more beneficial, depending on the ailment or condition being treated. (Leafly)
