Soon it could be illegal to smoke in public places in China, as the government considers tightening restrictions on the addictive habit. The new rules, which are being presented to the public for the first time this week, would also ban smoking at certain outdoor areas like sports venues, restrict selling of tobacco to minors and force tobacco companies to include warnings about the dangers of smoking prominently on their package labels, the New York Times reports. Smoking is incredibly popular in China: 300 million people partake regularly.
