According to a recent study, smoking Sheesha is a serious threat to the health of teenagers. This habit is common in the 17-25 years age group, with 65 percent Sheesha smokers being male, and 35 percent females. There is another dangerous thing about Sheesha and that is the use of prohibited and additive substances in more than 30 percent of Sheesha outlets by owners or by smokers. One puff of Sheesha contains more than 4800 active chemicals. Many of these chemicals are known to cause mouth and lung cancers, heart disease, respiratory and other diseases. According to a research of World Health Organisation the volume of smoke inhaled in an hour-long Sheesha session is estimated to be the equivalent of smoking between 100 and 200 cigarettes.Non-smokers, particularly pregnant women, babies, children and the elderly are at risk from breathing in Sheesha smoke. Sheesha has become a fashion in Pakistan and the younger generation somehow finds it more appealing than cigarettes, when it is known as more injurious to health. Sheesha bars use chemicals and sometimes even alcohol, in Sheesha to make it more pleasant. In my opinion, the government has work hard to implement the law banning Sheesha. But we all know, when it comes to the implementation, nothing is practiced as per law. In the rest of the world, the younger generation doesn’t find it as appealing as in Pakistan; as they are have other healthy recreational activities to keep them busy.ALTAMASH BIN SYED, Karachi, May 30.
