Delta-8

Delta-8 THC is an isomer of Delta-9 THC found naturally in trace amounts in cannabis. Most commercial Delta-8 is produced by isomerizing CBD. Effects are similar to Delta-9 THC but typically less intense, with users reporting reduced anxiety and mental fog. Delta-8 is federally legal as a hemp derivative when sourced from compliant hemp.

Example: Delta-8 carts were the first big hemp psychoactive wave in 2018-2020.

Etymology: Standard chemistry naming convention indicating the position of a carbon double bond.
