In a country where smoking is cheap and often described as a "national habit", an Egyptian government crackdown on shisha, the popular flavoured tobacco-filled water pipe, is facing stiff resistance.<br /><br />Egyptian authorities have issued an ultimatum to the owners of cafes in several cities across the country to stop offering shisha or face hefty fines.<br /><br />The crackdown comes as the government tries to enforce a two-year-old law banning smoking in public places.<br /><br />But as Al Jazeera's Rawya Rageh reports, many say a total ban on shisha would have a damaging effect on Egypt's vital tourism industry.
