In Pakistan, it is a crying shame that a culture of Shisha smoking has evolved and currently there are hundreds of cafes all around the country. The pity is that it is mostly teenagers who indulge in this activity. It becomes a real problem when they develop an addiction for it. The impression is given that it is a modern form of Hookah which is purely a white lie. In fact it is injurious to health and is even more dangerous than smoking. Cafes that are in this business should be sealed. HUSNA KHAN & RABAIL SHAD, Lahore, June15
