The World Health Organization (WHO) says that just 5 percent of the world's population live in nations where laws adequately protect the population from smoking.

Further, a new WHO report says, not a single country on Earth fully implements all six of the key tobacco-control measures, dubbed the MPOWER strategies. These include monitoring tobacco use and prevention policies, protecting people from tobacco smoke, offering help to quit tobacco use, warning about the dangers of tobacco, enforcing bans on tobacco advertising, promotion and sponsorship, and raising taxes on tobacco.

WHO also said that governments collect 500 times more money in tobacco taxes than they spend on smoking prevention.

"While efforts to combat tobacco are gaining momentum, virtually every country needs to do more,"  said Margaret Chan, director-general of WHO. "These six strategies are within the reach of every country, rich or poor and, when combined as a package, they offer us the best chance of reversing this growing epidemic."

The WHO also reported that 40 percent of countries still allow smoking in schools and hospitals, and just 5 percent of the world's population has access to tobacco-dependence treatment, are protected by smoke-free legislation, or live in nations where tobacco advertising and promotion is banned.
