If the commercial outfits are being run like companies, they won't taint their product with something that can kill their customers. The liability is too large. One case would kill the company. Even an unfounded accusation would do significant damage.
These companies are already on pins and needles about what the FDA is going to do with regard to their products. As I understand it, so far, the FDA has done nothing but issue some general public warnings.
Just teasing here... Is the “speak no evil against weed” rubbing off on you? :)
Personally as a true ex-pothead who no longer cares about it, I’m not at all concerned what happens to commercial businesses who deal weed. It is just more “dumbing down” of this country and has no positive aspects. Even what tax revenue is collected is being spent on more woke dumbing down garbage...
