It's smoking tobacco and drinking alcohol – and not taking illegal drugs – that pose the greatest risks to people's health, a new international study contends.
Worldwide, more than one in seven adults smoke tobacco, and one in five reports at least one occasion of heavy drinking in the past month, the review of 2015 data found
In South Africa, 5% of women may be considered to be risky drinkers whereas 28% of men are considered risky drinkers. Risky drinkers are defined as “someone who has drunk five or more standard measurements of alcohol on a single occasion in the past 30 days”.
Those same areas also have the highest rates of tobacco smoking – Eastern Europe 24.2%, Central Europe 23.7%, and Western Europe almost 21%. According to Stats SA, 6% of women smoke tobacco daily, compared to 30% of men in South Africa.
