Cannabis
(Cán-na-bis)
is a genus of
flowering plants that includes three putative
species, Cannabis sativa L.,[1] Cannabis in-
dica Lam.,[1] and Cannabis ruderalis Janisch.
These three taxa are indigenous to Central
Asia, South Asia[2], and surrounding regions.
Cannabis has long been used for fibre
(hemp), for medicinal purposes, and as a re-
creational drug. Industrial hemp products are
made from Cannabis plants selected to pro-
duce an abundance of fiber and minimal
levels of THC (Δ9- tetrahydrocannabinol), a
psychoactive molecule that produces the

"high" associated with marijuana. The psy-
choactive consists of dried flowers and leaves
of plants selected to produce high levels of
THC. Various extracts including hashish and
hash oil are also produced from the plant.[3]
Etymology
The plant name cannabis
is from Greek
κάνναβις (kánnabis), via Latin cannabis, a
Scythian or Thracian word, also loaned into
Persian as kanab. English hemp (Old English
hænep) may be an early loan (predating
Grimm’s Law) from the same source. In
Hebrew, the word is קַנַּבּוֹס [qanːa’boːs]. Old
Akkadian
qunnabtu,
Neo-Assyrian
and
Neo-Babylonian qunnabu were used to refer
to the plant.[4][5]
The further origin of the Scythian term is
uncertain.

Cannabis is an annual, dioecious, flowering
herb. The leaves are palmately compound,
with serrate leaflets. The first pair of leaves
usually have a single leaflet, the number
gradually increasing up to a maximum of
about thirteen leaflets per leaf (usually seven
or nine), depending on variety and growing
conditions. At the top of a flowering plant,
this number again diminishes to a single leaf-
let per leaf. The lower leaf pairs usually oc
