There's also the question of CBD's legality – something that's a lot grayer than the black-and-white picture most companies paint. The U.S. Drug Enforcement Administration considers CBD, like all cannabinoids, a schedule 1 drug. That means it's just as illegal as heroin and ecstasy. Meanwhile, hemp – a variety of the cannabis plant regulated by the U.S. Department of Agriculture – is legal , so long as its THC content is negligibly low. But because the agriculture department doesn't test for CBD – only THC – in hemp, more companies are getting away with selling products they say contain CBD, says Sara Jane Ward, an assistant professor of pharmacology at the Temple University Lewis Katz School of Medicine who's been studying CBD in rodent models for more than 10 years. Needless to say, the legality of CBD is "very confusing and very gray," she says.
Herrera and her patients aren't the only ones doling out rave reviews for CBD oil, which can be found online and in cannabis dispensaries, as well as in some grocery stores and even as an optional add-in alongside protein powder at your local juice chain. The oil has been riding the coattails of the growing legal cannabis industry, with one industry expert, Matt Karnes, telling Forbes in 2016 that he expected CBD products to become an almost $3 billion market by 2021.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
After an accident at his workplace that saw Rick Simpson suffer from dizzy spells and tinnitus, Simpson saw a documentary highlighting the positive benefits of using cannabis. He approached his doctor about using cannabis as a treatment, however, his doctor refused. Undeterred, Simpson sourced it for himself. After a short time, he started seeing an improvement in his symptoms and continued to use cannabis as a treatment.
Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
If this is not sufficient for calming your symptoms, a gradual increase of another 25 mg per day, over the course of 3-4 weeks, is recommended. While there have been no reports of more serious side effects when this oil is taken in larger concentrations, it is best to slowly increase your dose to find a comfortable and effective level, given your individual characteristics and needs.

On a molecular level, all classes of cannabinoid are derived from the cannabinoid cannabigerol (CBG). Cannabinoids are changed from their original acid forms by decarboxylation through heat, light, or alkaline conditions, allowing them to interact fully with the endocannabinoid system.

Not much, as far as humans are concerned—at least not yet. The vast majority of studies have been on animals, as of yet, and there are few high-quality studies on humans. Even the oil’s effect on pain—something that CBD oil is popularly used for—isn’t proven. “The studies available are small or not well designed,” says Dr. Devinsky. “There’s a lot of religion out there, but not a lot of data.”
