I live in Canada where there is legal weed, and even some of the legal cannabis makes you sick because it’s grown with chemicals and not flushed or it’s contaminated with powdered mildew or other shit. And it’s able to pass what little QC there is, and it makes me sick. So I buy from people that have been doing it for decades and smoke their own stuff as QC. If it’s too strong smoke less, but clean cannabis is the solution for that.
