THC

THC (tetrahydrocannabinol) usually refers to the naturally existing isomer of delta-9-THC, but also may include delta-8-THC. Delta-9-tetrahydrocannabinol and delta-1-tetrahydrocannabinol are two names for the same molecule according to different numbering systems (monoterpenoid and dibenzopyran nomenclature). Generally the natural (-)-trans-isomer of delta-9-THC of the cannabis plant, the (-)-delta-9-trans-tetrahydrocannabinol or dronabinol is designated. Chemically, delta-9-THC is defined as (6aR-trans)-6a,7,8,10a-tetrahy-dro6,6,9-trimethyl-3-pentyl-6H-dibenzo[b,d]pyran-1-ol with a molecular weight of 314.47 Da.
