What is Delta-8? Cleveland Clinic

Like CBD, delta-8 (delta-8 tetrahydrocannabinol) is just one of more than 100 chemical compounds found in the cannabis sativa plant. Most people are familiar with THC (delta-9 tetrahydrocannabinol), the main psychoactive compound in cannabis that gives you a euphoric high.
The 2018 Farm Bill legalized the production and sale of CBD products (which don’t get you high) on the federal level in the U.S. as long as they contain less than .3% of THC. In theory, this would allow federal legalization of CBD products with delta-8 under those same guidelines, but doctors, like internal medicine specialist Paul Terpeluk, DO, are expressing concerns about delta-8 products because delta-8 is psychoactive and produces same or similar highs as THC.
