While the amount of smokers in the U.K. has dropped to an all-time low, related diseases still kill thousands of people in the nation each year. 34 years ago, however, smoking was far more common in the United Kingdom, with more than a third of the population lighting up. That’s the year when the country instituted “No Smoking Day,” a national day to increase awareness of smoking related diseases and health problems. While one holiday surely isn’t the only reason why so many Brits have given up their smoking habit, it remains a powerful example of the big difference awareness can make when it comes to preventing tobacco abuse.
