The phenomenon they’ve identified doesn’t seem to be cannabis-specific at all. The finding really seems to be, “capitalism will pursue profits at the expense of customers’ well-being”.

Which isn’t going to be news to anyone but the most deluded libertarian. It’s a great example of why we absolutely need government to impose sensible regulations on business, because otherwise short-term profiteering will win over long-term societal good.

Cannabis, as it moves from illegal black markets to legitimacy, is just in an interesting position to highlight these kinds of effects.
