Products that contain less than 0.3% THC will not cause any psychotropic effects. You will be able to take these cannabidiol products with ease, without any unwanted side effects. These minimal amounts of THC allow for products to be legal within the United States’ federal mandate.

Cannabidiol (CBD) is a phytocannabinoid one of 113 identified cannabinoids in cannabis plants, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant’s extract. Medically, it is an anticonvulsant used to treat multiple forms of epilepsy. It was discovered in 1940 and, as of 2024 clinical research on CBD included studies related to the treatment of anxiety, addiction, psychosis, movement disorders, and pain, but there is insufficient high-quality evidence that CBD is effective for these conditions. CBD is sold as an herbal dietary supplement and promoted with yet unproven claims of particular therapeutic effects.

In 2018, the U.S. Congress passed and signed into law the Agriculture Improvement Act. This law removed hemp from the federal Controlled Substances Act, effectively legalizing CBD if it comes from hemp. However, a few states have not removed hemp from their state’s-controlled substances acts, so legality of CBD products differs across states. The most restrictive states, Idaho and Nebraska, require products to be 100% THC-free.
