A wealth of marketing material, blogs and anecdotes claim that cannabis oils can cure whatever ails you, even cancer. But the limited research doesn't suggest that cannabis oil should take the place of conventional medication, except for in two very rare forms of epilepsy (and even then, it's recommended only as a last-resort treatment). And, experts caution that because cannabis oil and other cannabis-based products are not regulated or tested for safety by the government or any third-party agency, it's difficult for consumers to know exactly what they're getting.
Cowen’s January consumer survey of approximately 2,500 adults found 6.9 percent of respondents use CBD as a supplement. “This initial response piqued our interest considerably, as it was much higher than we would have suspected,” and compared to 4.2 percent who reported use of Juul Labs Inc.’s e-cigarette devices and 19.6 percent who consider themselves current tobacco users, analyst Vivien Azer said in a note.
Even as the research proceeds, thousands of people are using CBD as medicine. A British pharmaceutical company, GW Pharma, has developed two CBD drugs: Sativex, which contains a 1-to-1 ratio of CBD and THC, and Epidiolex, which is pure CBD. The former is prescribed for the painful muscle spasms that occur in multiple sclerosis, while the latter is aimed at childhood seizures. Sativex is not available in the United States, but it is approved in 29 other countries, including Canada, England and Israel.
It’s worth noting, too, that Harvard epidemiologist Karin Michels recently called coconut oil “pure poison” and “one of the worst foods you can eat” during a lecture on nutrition — because it contains such high levels of saturated fat — which has since sparked outrage among both Americans and Indians (who live in a country where coconut oil is a dietary staple). Who’s right remains unclear, but one thing’s for sure: Cooking oils, especially those high in saturated fat (like coconut oil), should be used sparingly.

There is no scientific evidence or research on CBD as an effective treatment for migraine—in large part because it has not been formally studied. However, it may still be a viable topical option for some patients with joint and muscle pain associated with migraine. “If you have a lot of neck pain or soreness, it is perfectly reasonable to use CBD oil. It may even prevent nausea and vomiting,” Dr. Silberstein says.
The main points are to use cooking oils in moderation, Lichtenstein said. The government's U.S. Dietary Guidelines recommend that Americans include a small amount of oils in their diets every day to supply essential fatty acids, because the body can't make these acids and thus must get them from food. There are two such fatty acids, and both are polyunsaturated fatty acids: linoleic acid and alpha-linolenic acid.
Figuring out how much CBD oil to take can feel like trying to navigate through a complicated maze. The sheer volume of CBD brands on the market can create confusion for consumers, and when you take a closer look, it’s not difficult to understand why. Not only do vendors use different source materials (CBD-rich cannabis vs. industrial hemp, different strains, etc.), but they also implement different extraction techniques .
Keep in mind, too, that CBD product companies use different CBD sources, extraction methods and production techniques – and not all resulting products are created equal. You'll have to do your own research to determine which companies you're willing to trust, Asquith says. Plus, how the products are packaged and consumed – be they in oils, creams or capsules – affect how they're absorbed in the body. Edibles, for example, are well-absorbed, while oils taken under the tongue are "baloney," Tishler says. And of course, salespeople at herb shops don't have the same mission, knowledge, training or oversight as physicians and pharmacists. "We have spent the last 100 years or so developing the pharmaceutical system because it works," Tishler says.
