Delta-3-Tetrahydrocannabinol (Delta-3-THC, Δ3-THC, Δ6a(10a)-THC, EA-1477) is a synthetic isomer of
tetrahydrocannabinol Tetrahydrocannabinol (THC) is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term ''THC'' ...

plant. While the normal ''trans'' configuration of THC is in this case flattened by the double bond, it still has two enantiomers as the 9-methyl group can exist in an (R) or (S) conformation. The (S) enantiomer has similar effects to Δ9-THC though with several times lower potency, while the (R) enantiomer is many times less active or inactive, depending on the assay used.
