The medicinal use of Cannabis is increasing as countries worldwide are setting up official programs to provide patients with access to safe sources of medicinal-grade Cannabis. An important question that remains to be answered is which of the many varieties of Cannabis should be made available for medicinal use. Drug varieties of Cannabis are commonly distinguished through the use of popular names, with a major distinction being made between Indica and Sativa types. Although more than 700…

Cannabis: From Cultivar to Chemovar II—A Metabolomics Approach to Cannabis Classification
TLDR
This study represents the analysis of the widest range of cannabis constituents published to date and indicates the usefulness of a metabolomics approach for chemotaxonomic mapping of cannabis varieties for medical use.
Cannabis: From Cultivar to Chemovar II—A Metabolomics Approach to Cannabis Classification
TLDR
A metabolomics approach, combining detailed chemical composition data with cultural information available for a wide range of cannabis samples, can help to bridge the existing gap between scientists and patients.
Classification of Cannabis sativa L. in Relation to Agricultural, Biotechnological, Medical and Recreational Utilization
Cannabis sativa has been utilized for millennia, primarily as a source of a stem fiber (both the plant and the fiber termed “hemp”) and a resinous intoxicant (the plant and its drug preparations
Chemical Profiling of Medical Cannabis Extracts
TLDR
This investigation investigated the extract from a popular commercial strain of medical cannabis, prior to and after decarboxylation, to understand the chemical profiles and revealed the chemical complexity of commercial medical cannabis extracts.

TLDR
This review examines the evolving ways Cannabis has been used from ancient times to the present, and how human selection has altered the morphology, chemistry, distribution and ecology of domesticated forms by comparison with related wild plants.
Terpenoid Chemoprofiles Distinguish Drug-type Cannabis sativa L. Cultivars in Nevada
TLDR
It is proposed that three terpenoid cluster assignments account for the diversity of drug type cannabis strains currently being grown in Nevada and are distinguishable by terpene profiles alone.
Cannabis Oil: chemical evaluation of an upcoming cannabis-based medicine
Concentrated cannabis extracts, also known as Cannabis oils because of their sticky and viscous appearance, are becoming increasingly popular among self-medicating patients as a claimed cure for
The phytochemical diversity of commercial Cannabis in the United States
TLDR
Analyzing the cannabinoid and terpene content of commercial Cannabis samples across six US states shows that commercial labels do not consistently align with the observed chemical diversity, however, certain labels do show a biased association with specific chemotypes.

An evaluation of the quality of medicinal grade cannabis in the Netherlands
TLDR
Results show that medicinal cannabis offered through the pharmacies is more reliable and safer for the health of medical users of cannabis.
A chemotaxonomic analysis of cannabinoid variation in Cannabis (Cannabaceae).
TLDR
A two-species concept of Cannabis is supported by the determined frequencies of B(D) and B(T) in sample populations of 157 Cannabis accessions determined from CBD and THC banding patterns, visualized by starch gel electrophoresis.
The inheritance of chemical phenotype in Cannabissativa L. (IV): cannabinoid-free plants
TLDR
Backcrossing produced cannabinoid-free homologues of pharmaceutical production clones with potential applications in pharmacological research and suggests that locus O governs a reaction in the pathway towards the phenolic cannabinoid precursors.
Mississippi-grown Cannabis sativa L: preliminary observation on chemical definition of phenotype and variations in tetrahydrocannabinol content versus age, sex, and plant part.
TLDR
Nine strains of Cannabis sativa L. sativa (marijuana) were grown for research by the University of Mississippi and the cannabinoid content was determined using GLC, and the material was divided into two chemical phenotypes according to cannabinoid content.
The inheritance of chemical phenotype in Cannabis sativa L.
TLDR
Four crosses were made between inbred Cannabis sativa plants with pure cannabidiol (CBD) and pure Delta-9-tetrahydrocannabinol (THC) chemotypes, and it is suggested that codominance is due to the codification by the two alleles for different isoforms of the same synthase, having different specificity for the conversion of the common precursor cannabigerol into CBD or THC.
