this study is just as relevant to Gaia as to Canopy Growth

'..Acute and long-term exposure studies of CBD at physiologically relevant concentrations were studied in the worm model Caenorhabditis elegans (C. elegans) on the basis that 60-80% of their genes are shared with humans, and their comparatively short lifespan of 2-3 weeks makes such studies feasible. In the C. elegans model, which is recognized as a valid model for this kind of research, CBD did not demonstrate any degree of acute or life-long toxicity or related liabilities at physiological concentrations. Instead, CBD extended mean lifespan up to 18% and increased late-stage life activity by up to 206% compared to the untreated controls within the study...'

obviously this is pretty big in both respects , increased remaining lifespan and a more active late stage life. Who wouldn't want to have a more productive (in the late-stage) and longer life, seems pretty universal
