Pakistan allowed the free sale and consumption of alcohol for three decades from 1947, but restrictions were introduced by Zulfikar Ali Bhutto just weeks before he was removed as prime minister in 1977. Since then, only members of non-Muslim minorities such as Hindus, Christians and Zoroastrians are allowed to apply for alcohol permits. The monthly quota is dependent upon one's income, but is actually about five bottles of liquor or 100 bottles of beer. In a country of 180 million, only about 60 outlets are allowed to sell alcohol. The Murree Brewery in Rawalpindi was once the only legal brewery, but today there are more. The ban officially is enforced by the country's Islamic Ideology Council, but it is not strictly policed. Members of religious minorities, however, often sell their liquor permits to Muslims as part of a continuing black market trade in alcohol.
