World No Tobacco Day — May 31, 2012

摘要

Tobacco use is the leading preventable cause of death worldwide. Approximately 6 million deaths related to tobacco use occur each year, including 600,000 from second-hand smoke. If current trends continue, according to the World Health Organization (WHO), by 2030, approximately 8 million persons will die each year from tobacco use, and 80% of those persons will reside in low- and middle-income countries (1).
