The general information out there says that the PNW doesn't really have enough heat to grow tobacco well. And in any case, tobacco is really more of a tropical plant and wouldn't be able to survive the winters so far up North and would have to be replanted every year.

That's not what this man found when he actually tried growing it:

Apparently it grows lush and big, and even more remarkable, behaves as a perennial, coming back after the winter. (He lives in western part of WA state)

The deer also generally avoid it.

He says the plants with their big leaves can be very ornamental, and the flowers attract pollinators.

Even if you're not interested in growing conventional tobacco, there are other ornamental flowering tobacco species that can be very fragrant.
