Two researchers are urging greater regulatory oversight of e-cigarettes in poorer countries, where sales of the devices are growing. Public awareness of the devices is high in some developing countries. In the recent International Tobacco Control survey, 34 percent of adults in Mexico, 35 percent in Brazil and 62 percent in Malaysia said they had heard about the devices or tried them. In some of the poorest regions of the world -- notably Africa and South Asia -- there is little known about e-cigarette use, though these are vast potential markets, the authors wrote.
