I think what the article is saying is that marijuana tends to be grown frequently in the feeding grounds of owls, more so than other non-marijuana crops. In addition, the unregulated nature of growing marijuana means the regulators can't track what's going on, or punish infringement. Overuse of poisons by mainstream farms is a problem, but a different one. That said, I couldn't see any real data here. I don't know whether this is a bigger problem than people using rat poison in general, or putting slug pellets around their lettuces.
