According to Harvard Health, CBD is the second most abundant chemical in cannabis—the first being tetrahydrocannabinol, or THC. What’s the difference? THC is psychoactive and causes feelings of intoxication, while CBD is non-psychoactive—meaning it doesn’t produce the sensations commonly associated with being “high.” CBD is extracted from the cannabis plant into oil form so that it is isolated from THC, which is likely a main reason for its mass market, almost entirely legal, appeal.

Because ingesting CBD will not produce intoxicating effects like the ones you’d get from THC, CBD oil and other CBD products like edible gummies, body lotions, and topical balms are, for the most part, completely legal in the United States. CBD is considered legal on a federal level in the U.S. and the same is true on a state level across the country except for three states. In Idaho, Nebraska, and South Dakota, all forms of marijuana and CBD are still considered illegal substances. But if you don’t live in one of those states, chances are that CBD products can be purchased over the counter at your local drugstore.

The most common reasons people use CBD are for reducing inflammation, easing aches and pains, mitigating stress and anxiety, and improving sleep. However, while there is plenty of research to show that THC can be effective at treating chronic pain, anxiety, depression, nausea and vomiting, and insomnia, the jury is still out on CBD. “There needs to be more large-scale clinical trials where we can confirm that CBD is, in fact, effective,” Krista Lisdahl, PhD, the director of the University of Wisconsin-Milwaukee’s Brain Imaging and Neuropsychology Laboratory, recently told ESPN. Lisdahl said she could not recommend CBD usage due to the limited amount of proof that it does what its marketers claim it can. CBD products aren’t merely marketed as remedies for humans; there are similar products designed for dogs and other pets that claim to have the same benefits as the ones offered to people. But before you go mixing a little CBD oil into your pet’s food to calm them down during a thunderstorm, make sure to do your research. There have been several lawsuits regarding the validity and efficacy of CBD pet products and the U.S. Food and Drug Administration is currently in the process of issuing a draft enforcement policy on cannabis-derived compounds.
