An interesting but not unsurprising chart. Pretty much every smoker in the world knows that if you quit smoking you start to get chubby and generally non-smokers tend to be a lot more chubby compared to smokers. And that's not forgetting that smokers have marginally lower blood pressure than our non-smoking friends and becoming a quitter increases your risk of high blood pressure independent of weight gain, see below.
Given that we are told that tobacco kills 6 million people world wide and that obesity and high blood pressure kills 6 million people world wide (source VGIF) . It would seem that the merchants of death in the tobacco control industry are giving the merchants of death in the tobacco industry a run for their money.
The difference being that the merchants of death in the tobacco control industry want to make you fat and ugly before they kill you and you don't get to spend a life time enjoying smoking.
It will be interesting to see if e-cig users have increased risk of weight gain and high blood pressure, time will tell. In the mean time I am sticking to lovely cigarettes.
