Just to be clear, most cannabis plants that are grown to the point of allowing the trichomes to produce thc won't have much cbga left in them... cannabigerolic acid is a precursor the plant manufactures on the metabolic pathway to make tetrahydrocannabinol-acid thca... cannabidiol-acid or cbda is however mostly completed production by most strains of cannabis when the plant is mature enough for harvest... There is also strains that produce cbga but they are rare, as most breeding occurs for thca, leaving cbda and other cannabinoids more at trace levels. Also, the act of heating the plant to smoke it decarboxylates the compounds removing the co2 molecules, changing from acid form to the forms we know and love... destroying the efficacy of the molecules for this purpose... would have to use in edibles to get the efficacy... hemps would be the best category for this intended use...

Quite profound. Your knowledge of chemistry is formidable.
