I think that's the point, though: legal marijuana farms are an industrial process. The fact that we can put them in the same category as a paper mill is noteworthy. I'd agree that they're less offensive to the sense of smell than paper mills, or dog food manufacturing, or any number of other large scale commercial operations. But now that recreational marijuana is legal in so many places we have to consider (and regulate) it like the industrial process that it is.
