This paper presents a scoping review of recent literature regarding the phylogenetics of Cannabis, descending the taxonomic ranks of family, genus, species, subspecies, and varieties. The family Cannabaceæ now consists of ten genera. Cannabis is a monotypic genus consisting of one species, Cannabis sativa L. The monotypic model is supported by DNA “barcode” studies. Two subspecies are recognized, and the number of varieties has increased to six. When and where Cannabis evolved has been explored, using molecular clock analyses and fossil pollen studies, respectively. The ubiquitous vernacular taxonomy of drug-type plants— “Sativa” and “Indica”—is deconstructed, and placed in a formal botanical framework. Italy has been a crossroads of Cannabis fiber-type plant genotypes, between Europe and Asia.

本文对有关大麻的系统发育的最新文献进行了简要的回顾，对家庭，属，种，亚种和变种的分类学等级进行了排序。Cannabaceæ家族现在由十个属组成。大麻是由一种大麻（Cannabis sativa L）组成的单型属。单型模型得到DNA“条形码”研究的支持。公认有两个亚种，品种数量增加到六个。何时何地大麻分别使用分子钟分析和化石花粉研究探索了进化。销毁了无处不在的“ Sativa”和“ Indica”等毒品类型的植物分类，并将其置于正式的植物学框架内。在欧洲和亚洲之间，意大利一直是大麻纤维型植物基因型的十字路口。
