A dry, shredded green/brown mix of flowers, stems, seeds, and leaves of the plant Cannabis sativa, it usually is smoked as a cigarette (joint, nail), or in a pipe (bong). It also is smoked in blunts, which are cigars that have been emptied of tobacco and refilled with marijuana, often in combination with another drug. It might also be mixed in food or brewed as a tea. As a more concentrated, resinous form it is called hashish and, as a sticky black liquid, hash oil. Marijuana smoke has a pungent and distinctive, usually sweet-and-sour odor...

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."
