The Emirates Standardisation and Metrology Authority (Esma) has introduced new regulations making testing and registration of all tobacco packs, including the flavoured products used for shisha, mandatory from the beginning of this month, Gulf News has reported. The move is part of Esma's efforts to filter out life-threatening ingredients from tobacco products. "Smoking as a practice is injurious to health. We at Esma are trying to limit the damage," said Abdullah Al Muaini, director of conformity at Esma. The new rules, which have already been in place for cigarettes, force all manufacturers and importers of tobacco products to get Esma approval and certification before the products hit the market.
