> A fifth of the world's population is Muslim, and most Muslims live in areas where the prevalence of smoking is high and often increasing. But even among the many Muslims living in Europe, smoking prevalence (particularly among men) remains high. For example, in England in 2004 the overall prevalence of smoking was 40% in Bangladeshi men and 29% in Pakistani men compared with 24% among the male general population.
