Speaking of smoking, there are some start-ups that developed a tobacco plant that, when burned and smoked, reduces the risk of cancer and other diseases close to zero. At the current stage of development, the new cigarettes would be somewhat more expensive than the regular ones, and the taste would be a little off. However, it is expected that in a couple of decades tops, the costs and taste would become the same.

Now, would you switch to cigarettes that are a little more inefficient than the current ones, but pose no risk to your health? Or would you continue to chop away your life expectancy, presumably waiting to see if indeed smoking kills you as well?
