wow. The comments are just filled tobacco sympathizers. I thought the topic was closed after decades upon decades of research. My guess some people wouldn't mind to see the world burn tomorrow if they make profit today.
Science is descriptive, not prescriptive.
The actions individuals and societies take based on that information are based on their own subjective values.
Seriously though both tobacco and a lot of other “whatever they want” crops have mountains of externalized costs and societal consequences
Finally we'd be able to get blackcurrant in this country again. Shame about the pine blister rust and consequent devastation to forests and logging, but that's the price of freedom I guess.
