THC-O is also known as THC-O Acetate or ATHC (not to be confused with THCA) and is a manmade analog of Delta 8 THC, meaning that it does not naturally occur in the cannabis plant. To produce THC-O, CBD is converted into Delta 8 and then an organic solvent acetic anhydride is added for final conversion.
THC-O acts as a prodrug, meaning it only activates after its processed by your digestive system. It is common for effects not to be felt until around an hour or so. Effects have been reported to be up to 3X as potent as Delta 8 THC.
