CBD and CBD Oil: What Is It and Does It Really Work?

The popularity of medical marijuana is soaring, and among the numerous products consumers are seeking are CBD, or cannabis oils.

A wealth of marketing material, blogs and anecdotes claim that CBD 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 CBD 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.

What is CBD?

Simply put, cannabis oil is the concentrated liquid extract of the marijuana plant, Cannabis sativa.

Similar to other herbal extracts, the chemicals in cannabis oils vary depending on how the extract is made and what chemicals were in the plant to begin with. 

Cannabis plants produce thousands of compounds but the most well recognized belong to a class called cannabinoids. There are several cannabinoids but the two that are most well-known among consumers are THC (tetrahydrocannabinol) and CBD (cannabidiol).

THC is the primary psychoactive compound in marijuana and it is what people are searching for when they want a product that gives them a "high." Unlike THC, CBD isn't known to cause psychoactive effects, and is therefore attractive to those who want to avoid the high but who believe there are other benefits of CBD, said Sara Ward, a pharmacologist at Temple University in Philadelphia.

CBD products that don't contain THC fall outside the scope of the U.S. Drug Enforcement Agency's (DEA) Controlled Substances Act, which means CBD products are legal to sell and consume as long as they don't have THC. That's likely one of the reasons why CBD products, including CBD oil, are becoming more socially acceptable and increasingly popular. In 2016, Forbes reported that CBD products are expected to be a $2.2 billion industry by 2020.

How are CBD oils consumed?

The physiological effects of cannabinoids can vary widely from person to person, and also depend on how they're consumed. That lack of predictability is one of the reasons why cannabis oil is a challenging candidate for developing into a medicine, Ward told Live Science.

"Two people may eat a brownie [made with cannabis oil] and one may absorb massive amounts of cannabinoids and the other may not," Ward said. "How long it takes to work and how long it stays in the system differs greatly."
