What is Delta-8 THC and is It Legal or Not?

The National Cancer Institute in its definition of delta-8-THC defined it as an analog of tetrahydrocannabinol (THC) with antiemetic, anxiolytic, appetite-stimulating, analgesic, and neuroprotective property. Further clarification on the compound shows that it binds to CB1 and CB2 cannabinoid receptors located in the central nervous system. These cannabinoid receptors are G-protein coupled receptors. Upon binding to these receptors in the brain, delta-8-THC also causes a euphoric feeling though not as potent as delta-9-THC.
