The United Nations’ World Health Organization projects that a billion people will die prematurely from smoking this century. In the next 20 years, there will be nearly 1.6 billion smokers around the world. A Billion Lives takes a critical look at the history of smoking and the corruption that’s led to the current situation where safer, healthier alternatives are banned or heavily restricted in most countries, while the cigarette trade is continually protected. The film examines major conflicts of interest and corruption between governments, big pharmaceutical companies, and public health officials. It also takes a look at the history of e-cigarettes, as well as the role vapor technology and Swedish snus have played in the current health crisis.
