Delta-8 tetrahydrocannabinol (delta-8 THC) is a cannabinoid from Cannabis sativa. It's similar to delta-9 THC, the main psychoactive compound in cannabis.

Cannabinoids in cannabis work by binding to sites in the brain and on the nerves. Delta-8 THC is similar to delta-9 THC, but appears to be less psychoactive. The natural concentration of delta-8 THC in cannabis and hemp is low, so most delta-8 THC is synthetically made in a lab.

People use delta-8 THC for nausea and vomiting caused by cancer drug treatment, glaucoma, trouble sleeping, and many other conditions, but there is no good scientific evidence to support these uses.

Keep in mind that delta-8 THC hasn't been evaluated by the US FDA for safety, and legality isn't clear. It's banned in some states, and legal in others. Also, the amount of delta-8 THC in products might vary significantly. Some products might also contain contaminants.
