Cannabis sativa has a long history of cultivation dating back to at least 2,500 BCE. In that time many different varieties and cultivars have been developed for specific purposes such as fibre production (these forms are typically low in medicinally active compounds), oil-rich seeds, and medicinal/drug use. Selections grown for their mecicinally active compounds grow better and are more productive in tropical and subtropical regionss, whilst oil and fibre producing plants thrive better in the temperate and subtropical areas. Many of the cultivars and varieties have been named as to the locality where it is grown mainly. However, all so called varieties freely interbreed and produce various combinations of the characters. The form of the plant and the yield of fibre from it vary according to climate and particular variety.
Varieties cultivated particularly for their fibres have long stalks, branch very little, and yield only small quantities of seed and active compounds.
Varieties which are grown for the oil from their seed are short in height, mature early, produce large quantities of seed and varying quantities of active compounds.
Varieties grown for the active compounds are generally shorter, much-branched with smaller dark-green leaves.
Between these three main types of plants are numerous varieties which differ from the main one in height, extent of branching and other characteristics[
