Cannabis

Cannabis () is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, or all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species.

AI overview

Cannabis is a genus of flowering plants that originated in Asia and includes species commonly known as Cannabis sativa, Cannabis indica, and Cannabis ruderalis, though scientists disagree about whether these are separate species, subspecies, or variations of a single species. It matters because it is one of the most widely cultivated and culturally significant plants globally, with applications in medicine, industry, and recreation, making questions about its biological classification relevant to research, regulation, and policy.

Chanvre Cannabis (les cannabis) est un genre botanique qui rassemble des plantes annuelles de la famille des Cannabaceae. Ce sont toutes des plantes originaires d'Asie centrale ou d'Asie du Sud. La classification dans ce genre est encore discutée. Selon la majorité des auteurs il contiendrait une seule espèce, le Chanvre cultivé (Cannabis sativa L.), parfois subdivisée en plusieurs sous-espèces[1], généralement sativa, indica et ruderalis (syn. spontanea), tandis que d'autres considèrent que ce sont de simples variétés. Le cannabis est exploité de manière industrielle pour la qualité de ses fibres sous forme de « chanvre agricole » souvent pauvre en principe psychotrope (THC), tandis que le cannabis à destination d’usages récréatifs ou médicinal est riche en psychotropes (THC). De nombreuses lignées de cannabis ont été créées par l’être humain par hybridation entre sous-espèces ou variétés du genre, par sélection des plantes ou encore par le bouturage qui permet de les cloner à l'identique. Ainsi les plants sont triés en fonction de l'usage que l'on souhaite en faire : qualité de leurs fibres, richesse en huile de leurs graines (chènevis), leur faible taux de THC ou, au contraire,

The plant is also known as hemp, although this term is usually used to refer only to varieties cultivated for non-drug use. Hemp has long been used for fibre, seeds and their oils, leaves for use as vegetables, and juice. Industrial hemp textile products are made from cannabis plants selected to produce an abundance of fibre.
