It's very easy. There is no valid defense of cigarettes. The industry new they caused disease and lied about them. They hired Edward Bernays to market them to women. They paid doctors to sell them as health products. It's an unbelievable stretch just for the sake of argument and inability to admit being wrong on the internet to say that cigarettes are a positive advancement for humanity. WTF.

Always nice to be able to see the world so clearly black and white (btw., cigarettes have many hundreds of years of history you seem to ignore).
