Example text

In the early herbals the sexes were in fact erroneously assigned, with the plant bearing seeds referred to as seede hempe, male hempe or Cannabis mas and the plant bearing flowers alone referred to as barren hempe, female hempe or Cannabis femina. Occasionally monoecious plants are encountered bearing both male and female flowers; these may arise as a result of special breeding (Small and Cronquist, 1976). They are particularly frequent in varieties developed for hemp production (Clarke, 1981).

It is known that cannabis was imported into the country for coloured seamen and entertainers in London in the late 1940s (Zacune and Hensman, 1973). The spread of cannabis use was fuelled because of its association with the increasingly popular jazz scene, and because many of the immigrants entering Britain at this time had used the drug in their countries of origin. Usage was encouraged by avant garde literary figures of the era. As in the USA, it was not until the 1960s that cannabis smoking became fashionable with young white people, and it has remained popular ever since.

Cultivation of Cannabis for Hemp Fibre or Cannabis Seed Despite its widespread cultivation in Europe and North America in the late 19th and early 20th centuries, the large scale production of hemp for fibre or seed is now restricted to a few areas of Eastern Europe (Hungary, Romania, Ukraine, Russia, former Czechoslovakia, Serbia, Croatia) and China (De Meijer, 1995). This is partly due to a great reduction in the demand for hemp fibre following the advent of more attractive alternatives (synthetic or natural), and secondly due to concerns and restrictions throughout the world on the cultivation of cannabis for narcotic purposes.
