It's definitely not the best climate, but I believe any competent grower with knowledge of the specific craft of growing for extraction could do it. I might know someone who might have once attempted to look into getting known-stoned seeds to give it a go, but never found any sort of confirmation that these were the magic beans he was looking for so never made the attempt. The flowers come up just about everywhere without much effort - same is true of cannabis and tomatoes, but poppies will naturally come back wherever they establish themselves. Yes, the best herb grows wild in places like Jamaica with long summers, but you can grow quite a respectable crop outdoors where I live, about 200km north of North Dakota, especially if you've got a greenhouse, but even without, there are cultivars which are very amenable to short seasons. Not totally sure poppies completely transfer, knowledge-wise, like weed and tomatoes - if you can grow tomatoes, you can grow weed, by the way. But I'm pretty sure, and the article is seriously hinting, that that is at least somewhat the case, and it's definitely a crop that any competent farmer can just switch to, if their local environment is hospitable to it. I don't doubt that in Jefferson's day it was a more common home remedy than 20th century history books recorded.
