Cannabis belongs to the family of Cannabaceae; known to produce a unique family of terpeno-phenolic compounds called cannabinoids. The most well-known are Cannabidiol (CBD), the main component in industrial hemp, and Δ9-tetrahydrocannabinol (THC), the psychoactive component in Marijuana. Legality of cannabis varies by country. The policy of use in most countries is regulated by the United Nations Single Convention on Narcotic Drugs (1961), the Convention on Psychotropic Substances (1971) and the Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances (1988). More than 0.3% THC is considered to be illegal and not accepted for use and sale in many parts of the world.
In United States, California became the first state to legalize the medical use of cannabis with the passage of the Compassionate Use Act of 1996. In 2012 Colorado and Washington became the first states to legalize recreational use.

In South Africa, it is legal to possess and cultivate, but not sell.
With legalization, many companies are riding on the CBD wave and developing potential applications in order to garner a share in the market. The different combinations of CBD and THC that are possible creates huge opportunities for these players particularly in food, cosmetic and medical product areas. In the food and beverages area, cannabis infused food in the form of edibles and drinkables have already hit the market. Production of cannabis edibles requires appropriate testing for bio contaminants and pathogens. Infused edible products must indicate on the label that they have been tested for pesticides, heavy metals, mold, and residual solvents. No public safety guidelines or U.S. Food and Drug Administration label requirements exist, yet people with chronic medical conditions - cancer, Parkinson’s disease, ALS, Multiple sclerosis use these products for pain and symptom management.

CB1 and CB2 are the primary receptors of endocannabinoid system, playing a major role of expression in brain and immune system. They belong to a family of seven transmembrane Guanosine Binding Protein Coupled Receptors, widely expressed and distinguished by their specific functions, localization and signaling mechanisms. Major Cannabinoids have multiple targets within the central nervous system and can modulate activity of neurons, glia, and microglia. Tetrahydrocannabinol (THC) may also demonstrate anti-inflammatory effects independent of CB1 and CB2 receptors.
CBD has low affinity for CB1 and CB2 receptors. CBD’s anticonvulsant properties are linked to regulation of voltage gated potassium and sodium channels and GPR55. However, Delta-9-THC binds to other targets, modulates neuronal excitability and neuro-inflammation.
