Whether the drug and non-drug, cultivated and wild different types of Cannabis constitute just one, really variable species, or even the genus is polytypic with more than one species, continues to be a matter of debate for properly more than two centuries. That is a contentious difficulty mainly because there is not any universally accepted definition of a species.[53] Just one greatly applied criterion for species recognition is always that species are "groups of truly or possibly interbreeding organic populations that are reproductively isolated from other this sort of groups."[54] Populations which might be physiologically effective at interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes regarded as being different species.
Even though herbal cannabis and industrial hemp derive from your exact species and incorporate the psychoactive part (THC), These are distinctive strains with distinctive biochemical compositions and employs. Hemp has lower concentrations of THC and better concentrations of CBD, which decreases the psychoactive consequences[a hundred sixty five][166] Kief

He also concluded There's small assistance to treat C. ruderalis being a individual species from C. sativa at the moment, but additional investigate on wild and weedy populations is required since they have been underrepresented of their collection.

These versions have been assumed to acquire intercourse chromosome composition XX.[31] In accordance with other researchers, no contemporary karyotype of Cannabis had been released as of 1996.[32] Proponents in the XY technique condition that Y chromosome is a little much larger in comparison to the X, but hard to differentiate cytologically.[33]

The genus Cannabis was 1st categorised utilizing the "modern day" method of taxonomic nomenclature by Carl Linnaeus in 1753, who devised the process still in use for your naming of species.[59] He considered the genus to generally be monotypic, possessing just an individual species that he named Cannabis sativa L. (L. stands for Linnaeus, and indicates the authority who 1st named the check this species). Linnaeus was familiar with European hemp, which was extensively cultivated at some time. In 1785, pointed out evolutionary biologist Jean-Baptiste de Lamarck released a description of the 2nd species of Cannabis, which he named Cannabis indica Lam.[60] Lamarck centered his description from the freshly named species on plant specimens gathered in India.
