Bad habits are often hard to break because they really seem like they bring us some sort of pleasure, and whether physical or mental we start to miss that little habit when it's gone.
Missing the feeling of that cig in-between your fingers, that ritual of lighting, inhaling and snubbing out is a big part of what makes it so hard for smokers to quit, well, that and the highly addictive chemicals added to cigarettes to increase their nicotine levels.
As this comic by Jacob Andrews shows us those chemicals make you want to come back from the dead for a smoke!
