 Erect annual herb, up to 2m tall, native to Central Asia; stems fibrous; leaves palmate; flowers small, uni-sexual, wind-pollinated; fruit a nut, 3.5-5mm long and 2.5-4mm broad, gray (C.sativa subsp. sativa) or 2.5-3.5mm long and 1.8-2.5mm broad, brown (C.sativa subsp. spontanea Serebrjakova = Cannabis ruderalis Janisch.). Erect annual herb, up to 2m tall, native to Central Asia; stems fibrous; leaves palmate; flowers small, uni-sexual, wind-pollinated; fruit a nut, 3.5-5mm long and 2.5-4mm broad, gray (C.sativa subsp. sativa) or 2.5-3.5mm long and 1.8-2.5mm broad, brown (C.sativa subsp. spontanea Serebrjakova = Cannabis ruderalis Janisch.).
  
-Main components of the volatiles from fresh and dried hemp buds are monoterpenes (92%) like β-myrcene (67%/38%), limonene (both 16%) and linalool (2.8%/5.0%). Sesquiterpenes (7%) present in the oil of dried material are cis-sabinene hydrate (cis-thujanol), ipsdienol, cis-carveol, α-ylangene, β-elemene, (Z)-α-bergamotene, α-guaiene, α-cadinene, γ-muurolene,  γ-curcumene, viridiflorene (ledene), α-longipinene, γ-cis-bisabolene, γ-trans-bisabolene, β-eudesmol (β-selinenol), α-eudesmol (α-selinenol), and α-epi-bisabolol.  \\+Main components of the volatiles from fresh and dried hemp buds are monoterpenes like β-myrcene (67%/32%), limonene (16%/16%) and linalool (2.8%/5.0%).

 Cannabis herb and the resin, hashish, show clear differences in their volatile chemical profiles, mostly resulting from photooxidation. Hashish headspace contain remarkable amounts (1.1-14.9%, median value 10.2%) of the rare monoterpene 5,5-dimethyl-1-vinylbicyclo[2.1.1]hexane (hashishene). This unusual compound is formed  during the manufacture of hashish by light induced rearrangement of β-myrcene, which is particularly abundant in fresh cannabis herb. \\ Cannabis herb and the resin, hashish, show clear differences in their volatile chemical profiles, mostly resulting from photooxidation.
