Because now you aren't restricted to just hating smokers when you see them. Oh no, you can buy playing cards to remind you of how filthy, smelly and vile they are whilst playing poker with your smoker-hating mates (click to enlarge).
And just so you don't forget that it's not merely an aroma thing, these doozies will also point out how smokers are killing everyone else, causing carnage on the roads, and destroying the planet.
Not too keen on the jolly 'life' cards? No problem, there's always the 'death' set instead.
Brilliant, huh? Especially since all this demonisation of tobacco is producing such excellent results in deterring youth smoking. Isn't it?
