Cannabis and Cannabinoid ResearchAhead of Print Free Access Abstract Photochemistry is a powerful synthetic tool resulting in the construction of unique substances. Remarkably, photochemistry has been relatively underexplored in the cannabinoid area and represents a valuable opportunity for further discovery. Photochemistry involves the study of how radiant energy (usually ultraviolet [UV]) affects chemical changes and it predates the emergence of life on Earth.
