The only study that has tested the bioavailability of inhaled CBD is from 2014; it found a bioavailability of about 25 percent for 100 mg and 200 mg doses of CBD using a Volcano vaporizer. (The topical lotions are even less studied; there have been no clinical trials on them at all.) This is more efficient than ingesting CBD, in the same way that vaporizing THC is more efficient than eating it. To get an effect, you should ingest a different amount of CBD than you’d inhale ... but how much is that? How much is too much?
CBD is showing real promise as a compound that can contribute to protecting the brain, thanks to its anti-oxidant and anti-inflammatory abilities. Scientists are investigating its role in neurogenesis and its ability to help the brain heal from injury, and as a treatment for neurodegenerative disease. Research suggests that CBD may help to reduce brain damage from stroke or other neurological injury. And CBD is increasingly looked to as a possible therapy for several neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and multiple sclerosis.

In just a few years, cannabidiol (CBD) has become immensely popular around the world. After initially being discovered as an effective self-medication for Dravet syndrome in children, CBD is now sold and used to treat a wide range of medical conditions and lifestyle diseases. The cannabinoid CBD, a non-psychoactive isomer of the more infamous tetrahydrocannabinol (THC), is available in a growing number of administration modes, but the most commonly known is CBD oil. There are currently dozens, if not hundreds, of producers and sellers of CBD oils active in the market, and their number is increasing rapidly. Those involved vary from individuals who prepare oils on a small scale for family and (Facebook) friends to compounding pharmacies, pharmaceutical companies, and licensed cannabis producers. Despite the growing availability of CBD, many uncertainties remain about the legality, quality, and safety of this new “miracle cure.” As a result, CBD is under scrutiny on many levels, ranging from national health organizations and agricultural lobbyists to the WHO and FDA. The central question is whether CBD is simply a food supplement, an investigational new medicine, or even a narcotic. This overview paper looks into the known risks and issues related to the composition of CBD products, and makes recommendations for better regulatory control based on accurate labeling and more scientifically supported health claims. The intention of this paper is to create a better understanding of the benefits versus the risks of the current way CBD products are produced, used, and advertised.

Again, the more studies and medical research that focus on CBD, the more will be known about its side effects and potential medical benefits. For what it's worth, in December 2017, the World Health Organization declared in a report that "cannabidiol does not appear to have abuse potential or cause harm." The WHO also noted that CBD could have "therapeutic value" for epileptic seizures, but that further study is warranted to determine CBD's potential medical use.

Before I even checked the ingredients list and saw that cocoa seed butter was involved, my first impression was that this body butter smelled like chocolate, so much so that my stomach rumbled with hunger because it was 4pm and I hadn’t eaten lunch yet. Don’t the “whipped” descriptor fool you—unlike most body butters you’ve used, this formula is solid to the touch, a balm rather than a cream. But that might be exactly what you want if you’re looking for a CBD-infused treatment anyway—something that feels extra-nourishing and almost medicinal. Luckily, it smells incredible in a subtle, natural way, not like other body butters with artificial tropical fruit scents.


For ingested CBD, that fat solubility is a problem. “[Ingested] CBD has a very low bioavailability, something between 6 and 15 percent, which varies between people,” says Blessing. Because ingested CBD is so inefficient at actually getting to the brain to stimulate CB1 and other receptors, the doses shown to be effective have to be very high. “There’s no evidence that doses below 300 mg of CBD have any effect in any psychiatric measure,” says Blessing. “And in fact, dose-finding studies show that the lowest clinically effective dose of CBD for reducing anxiety is 300 mg.” Blessing is talking about induced anxiety in otherwise healthy patients, which is all we have studies on; studies of CBD’s efficacy in treating clinical anxiety, which would require regular doses, haven’t been published.

However, cannabidiol as an anxiety reducer has almost none of these issues. One study had 24 participants who took either 600 mg of CBD or a placebo drug. In a speaking test that followed, the group which underwent CBD treatment showed less anxiety. They also had a smaller degree of cognitive impairment and felt less discomfort overall as they spoke. In other words, their results were better than those of the placebo group.

This mint-green bath bomb, made by Los Angeles-based De La Beuh, combines the invigorating aromatherapy of peppermint oil with the pain relief benefits of CBD. I sat in the bath with this bath bomb soak for an hour—until the water ran cold—when I had both cramps and lower back aches, and while it doesn’t beat ingesting a painkiller, it did help soothe my pains so that I fell asleep as soon as I hit the pillow. De La Beuh sells bath bombs in many varieties—including a glittery Kaleidoscope version that will turn your bath into “unicorn” colors—so your preference just depends on your preferred aroma.
A few weeks ago, in a bike shop–slash–coffee shop in Williamsburg, Brooklyn, I saw a little sign for a new product on offer: a CBD lavender latte. I didn’t get one, in part because it was 80 degrees outside, and also because my experiences with CBD are somewhat mixed. I have some gummy fruit candy that puts me straight to sleep, and I found using an oil dropper on my tongue too disgusting-tasting to be worth whatever marginal benefits it may have given me. But I knew other anxious people have had good experiences with CBD, and I like coffee, so I was interested — though I did wonder if coffee (a stimulant) and CBD (a cannabinoid thought to have relaxing properties) might just cancel each other out.

It depends on the dose and the person. Dr. Bonni Goldstein, M.D., the medical director of Canna-Centers, notes that it’s hard to figure out how exactly CBD will affect individuals. “It’s unclear at this point in time the exact interaction between CBD and caffeine,” she says. “At low doses, CBD is a stimulant and in higher doses it can cause sedation....Someone’s reaction to a combination of these compounds would not be easily predictable because various doses of each would affect the response,” Goldstein explains.
