In Sri Lanka

  • In Sri Lanka a community survey of seven districts found 20 – 32 per cent current drinkers. In the rural area those who drink do so heavily. A survey in eight villages showed 71 per cent of respondents drinking daily. Use is higher among poor families. 93 per cent of respondents used locally produced alcohol, which is not reflected in the per capita consumption.
