Delta-8 THC is a psychoactive compound found in marijuana that is not well regulated by the government. While it produces similar effects to other forms of THC, it also poses health risks like hallucinations and vomiting. Producers claim it has fewer side effects than other THCs, but the FDA has serious concerns about its safety and warns against its use. Delta-8 THC was first discovered in the early 1900s but is now more popular as it can be manufactured from CBD oil.
