It’s a rapidly growing and highly lucrative industry. I would always look carefully at the ‘conflict of interest’ section at the bottom of any paper - things that are company funded may not be too trustworthy although they still get published. Then things like sample size and methodology.

On the other side, at the moment there appear to be many potential applications of these plants (hemp/cannabis) and I’m happy so much investigation is going on. Many of these studies are generating initial data that will give hints as to whether it’s worth studying them in greater detail. So I Iook forward to any interesting discoveries that emerge - and the larger replicative studies that then back up the initial hypothesis with robust and reliable evidence.
