U.S. health officials are warning about the potential dangers of “delta-8 THC,” a compound derived from marijuana, after seeing an increase in hospitalizations tied to the substance. On Tuesday (Sept. 14), both the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) alerted consumers of a recent rise in the availability of products containing delta-8 THC, as well as reports of adverse effects from the products. Delta-8 tetrahydrocannabinol (THC) is one of more than 100 compounds known as “cannabinoids” found in the cannabis plant. It is similar to delta-9 THC, the psychoactive compound that’s primarily responsible for the high people experience from marijuana. Delta-8 THC is estimated to be about 50% to 75% as psychoactive as delta-9 THC, but it’s naturally produced in only very low levels in the cannabis plant, according to the CDC.
