According to a World Health Organisation report, reckless alcohol consumption led to 3.3 million deaths worldwide, in 2012. Further, the report found that 16% of all alcohol consumers were guilty of binge drinking. Just for reference, binge drinking is defined as a pattern of drinking that raises Blood Alcohol Concentration levels to 0.08g/dL. In simple terms, this means 4 drinks for women and 5 for men, in about 2 hours.(source)
