How is it that My reading comprehension is poor when the truth is that those people have built their homes in areas which are not Zoned Residential?

Go to the trouble of zoning the area Residential, accept the increase in taxes and decrease of personal freedoms, and voila: grow operations Cannot by State law & Regulations set up operations in that neighborhood.

The ad hominem of presuming that my reading comprehension fails to understand your points fails in this regard.

My previous comment covered the fact that stoned drivers was and is a thing right now. Icy roads in Fairbanks have already had stoned drivers traversing them for as long as marijuana has been a thing in Alaska. 

I'll give you a hint: it happened well before 2014...
