This is exactly why production of cannabis should not be put in the hands of large corporate entities serving the entire country. When something goes wrong, people far and wide are impacted.
Cannabis production should be left to small independent producers, at least that way, if a bug does get into the crop, only the localized clientele are affected.
If we proceed as Trudeau apparently intends, licensing only a few national producers, then we will ultimately wind up with the same sort of problems we've experienced with centralized abattoirs, where a single germ can impact the well being of people clear across the country.
Someone needs to explain all this to Trudeau, and make sure he understands.
