At confer- ences like the Marijuana Business Conference and Expo, attendees weave through informative exhibition booths, short courses and oral pre- sentations that cover a myriad of marijuana re- lated topics, from tips and dispensary ‘budtender’ training to medical mar- ijuana extracted oils and edibles. Financial ex- perts, entrepreneurs, cannabis connoisseurs, laboratory chemists and a large contingency of novices intermingle to educate, share, learn and network. The energy level is exuberant, adrenal- ized with what seems to be unlimited opportu- nities. At the time of writing this article, 37 states have pro- medical cannabis laws, including 23 states (and DC) that have medical laws and 4 states that have full legalization. There are over 2,000,000 legal medical marijuana patients in the U.S.A., and nearly half of Americans are now living in states with some form of medical mari- juana or CBD legislation. As entrepreneurs posi- tion for highly coveted cultivation and dispensa- ry licenses and state regulators work diligently to bring new medical cannabis programs online, another exciting business opportunity has emerged. Cannabis testing laboratories are needed to accurately determine cannabinoid po- tencies in cannabis products, and ensure that these products are free from contaminants. New standards and best practices are being established by various associations in states where medical or recreational marijuana is le- gal. American Herbal Pharmacopoeia’s mono- graph outlines the quality control criteria need- ed for ensuring the identity, purity, and quality of cannabis materials. The American Oil Chemists’ Society (AOCS) has established a cannabis ex- pert panel, which convenes to improve cannabis testing. New conferences devoted entirely to cannabis testing and research, like CannCon Fig. 1. G.I. Grow’s natural sunlight biomedical farm (www.GIGrow.us).

The develops in early human embryonic stages and cannabinoid receptors play a critical role in brain develop- ment and foetal survival [3]. Researchers have become extremely interested in the endocan- nabinoid system as an emerging target of phar- macotherapeutics. Understanding and modulat- ing the activity of the endocannabinoid system appears to hold great therapeutic potential in “a wide range of disparate diseases and pathologi- cal conditions, ranging from mood and anxiety disorders, movement disorders such as Parkin- son's and Huntington's disease, neuropathic pain, multiple sclerosis and spinal cord injury, to cancer, atherosclerosis, myocardial infarction, stroke, hypertension, glaucoma, obesity/meta- bolic syndrome, and osteoporosis, to name just a few” [4]. It’s research like this, specializing in human health rather than human high, that best illus- trates the desperate need for standardization of procedures and cannabis test methods. Cannabis contains more than 500 com- pounds that are unique to cannabis, including over 80 cannabinoids. We will only begin to ap- preciate the therapeutic potential of cannabi- noids once cannabis research is allowed to take place in laboratories across the world.
