It's pretty much common knowledge that all insurance companies will charge higher life insurance premiums for smokers. Most I've had a quick look at seem to be double for smokers vs non-smokers based on usually on the lines of one very basic question like "Have you smoked tobacco products in the previous 12 months?"
Is anyone aware of any that will ask for more information as to how much and what format an individual smokes taking that into consideration in calculating their premium?
