What pisses me off is the frankly condescending way they muse about WHY he built it. "His business was doing so well, and nothing traumatic had happened to him, so what would POSSIBLY drive him to grow the Devil's Lettuce?"
I find the implication that only a desperate, downtrodden, shell of a man would consider growing marijuana (especially in a State that's already on the road to medical whole plant legalization!) incredibly insulting and ignorant. It's not a meth lab, dammit!
