More important than legality is understanding if CBD is safe for you. While studies are still ongoing about the long-term safety of CBD usage, most experts agree that it is easily tolerated by most adults with no significant side effects on mood, physiology, or the central nervous system. Many CBD products, including oils and tinctures, also allow you to customize your serving size, which can help you avoid or mitigate any potential side effects.
Food and beverage products containing CBD were introduced in the United States in 2017.[dubious – discuss] Hemp seed ingredients which do not naturally contain THC or CBD (but which may be contaminated with trace amounts on the outside during harvesting) were declared by the FDA as GRAS in December 2018. CBD itself has not been declared GRAS, and under U.S. federal law is illegal to sell as a food, dietary supplement, or animal feed. State laws vary considerably as non-medical cannabis and derived products have been legalized in some jurisdictions in the 2010s.
Multiple sclerosis (MS). A prescription-only nasal spray product (Sativex, GW Pharmaceuticals) containing both 9-delta-tetrahydrocannabinol (THC) and cannabidiol has been shown to be effective for improving pain, muscle-tightness, and urination frequency in people with MS. This product is used in over 25 countries outside of the United States. But there is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis when it is used alone. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness, but not muscle spasms, tiredness, bladder control, mobility, or well-being and quality of life in patients with MS.
The passage of the 2018 Farm Bill made it legal to sell hemp and hemp products in the U.S. But that doesn't mean that all hemp-derived cannabidiol products are legal. Since cannabidiol has been studied as a new drug, it can't be legally included in foods or dietary supplements. Also, cannabidiol can't be included in products marketed with therapeutic claims. Cannabidiol can only be included in "cosmetic" products and only if it contains less than 0.3% THC. But there are still products labeled as dietary supplements on the market that contain cannabidiol. The amount of cannabidiol contained in these products is not always reported accurately on the product label.
