Why Do People Keep Smoking Even Though They Know It’s Harmful?

I don’t smoke, but also I don’t look down on people who smoke.

But still, I can’t help but wonder: what’s so addictive about smoking? And why do people still choose to smoke up on all the warnings and health risks?

Just the other day I came across an empty pack of cigarettes. Lo and behold, they’ve graduated from just writing “smokers are liable to die young” to know using graphic images of a severely cigarette-damaged lung. All this in a to dissuade people from smoking.

So, my question is, why do people still smoke when the disadvantages are so glaring?
