Now a day’s cannabis is enormously using as for the drug abuse in India including other developing countries. The plant Cannabis sativa is also known as marijuana, presents unique issues in our justice system, not the least of which is its identification both by law enforcement officers as well as Forensic Crime Laboratories. Present work is aimed for identification of that biological evidence of Cannabis plant, which can enhance the suitability of identification. Comprehensive studies of both chemical and morphological methods have led investigators to conclude that the two approaches are complementary . In this morphological study was performed by using trinoccular biological research microscope while chemical study by colour/spot tests and Thin Layer Chromatography due to its ease of availability and handling. A combination of the two provides experienced analysts with a very reliable means for identifying Cannabis fragments. If any of the residue/fragments of Cannabis plant found at the crime scene, a Forensic Analyst (investigator) can adopt any of the identification technique as suitable as for their reliability . Some of the researchers have been already qualified these types of techniques but present study included the anatomy of root, stem, with their visual feature followed by chemical and instrumental techniques which can provide accuracy of identification.
