Since the 2018 Farm Bill legalized the production of hemp in the U.S., there’s been a massive increase in hemp-related products.

Hemp seed oil, also called hemp oil, has been around for decades, often sold at health food stores and used in cooking and skincare. The oil is made by pressing hemp seeds and has a 3:1 ratio of omega-6 to omega-3 essential fatty acids.

Refined hemp seed oil is clear and colorless, with little flavor, and is primarily used for body and skincare, while industrial hemp seed oil is used in lubricants, paints, inks, fuel and plastics.

Hemp and cannabis are two varieties of the same plant species, Cannabis sativa.

Because cannabidiol (CBD) and hemp seed oil are in the same cannabis family, they’re often incorrectly marketed as the same thing. The easiest way to check which is which is to check the ingredient list. Hemp seed oil will be listed as “cannabis sativa seed oil.”

Neither hemp seed oil nor CBD contain significant amounts of tetrahydrocannabinol (THC), the principal psychoactive element present in the cannabis plant.

But keep in mind: Despite the 2018 Farm Bill, the rules and regulations surrounding CBD and hemp-related products are complicated, so check your local laws for legality in your area before you add any of these products to your shelves.
