 The classification and uses of cannabis have been controversial but it is now known that they belong to the order Rosales, family cannabisi, genus cannabis, species, C sativa L, with both industrial hemp, C sativa L var. Sativa and narcotic C sativa L var. Indica. Hemp can be divided into several groups based on genetic plasticity, allowing adaptation to changing conditions, and the most important criteria are origin, length of vegetation period, cannabinoid content, mono, and dioequivalents. The species exhibits sexual dimorphism and the pharmaceutical use of hemp has been known for thousands of years with new bioactive compounds still being discovered, making its potential unfathomable.
