Cannabis: using scientific or slang names?

With both medical and recreational cannabis legalizing on the rise, it raises serious questions. Should we use the term “marijuana” or call it by its scientific name? Should cannabis strains of cannabis be classified as different species or keep them as sub-species? As an industry, how do we correctly and consistently name all of the types cannabis? Should medical and recreational cannabis have different names? Do cannabis users prefer to use slang names for the different strains, or would users prefer to have a scientific name to refer to each type of cannabis?
