The topic of smoking cigarettes is one of the most contentious issues in modern society. As more and more research is done on the effects that tobacco smoke has on not only the smoker themselves, but also anyone caught in the radius, or even the environment, it's becoming a less common practice.
The medical field has already decried the practice, with many areas being mandated by law to label cigarettes with pictures of what exactly extended periods of smoking will do to the body; browned teeth, cancerous livers, diseased lungs, you name it. Not only that, but more and more countries are forbidding smoking in places like bars and restaurants, where it was once commonplace. Even alternatives like e-cigarettes are being banned.
While plenty of smokers are lamenting this fact and are increasingly furious about having fewer places to smoke, these protests are falling on increasingly-deaf ears. Case and point: the Pope himself has now expressly forbidden cigarettes from being sold in the Vatican.
