Delhi is all set to ban e-cigarettes. Under provisions of law, sources in health ministry said, the government has already banned international expo on e-cigarettes in Delhi.

Recently, the government also denied permission to a huge consignment of e-cigarettes in Delhi. Its sale has already been banned in the six states because of its hazardous nature.

Therefore, the Delhi government is also working hard to stop the danger of tobacco use along with electronic nicotine device.

Dr SK Arora, director of Delhi State Tobacco Control Cell, told Mail Today, "Ecigarette is an addictive device and toxic in nature. Though, e-cigarette ban in Delhi is still under process, however, in the absence of legal provisions, we were able to close one of the Chinese stalls selling e-cigarettes at India International Trade Fair.

"We got the huge consignments of e-cigarettes entering India through Delhi international airport cancelled and the first international Vapexpo event promoting e-cigarettes got cancelled first in Delhi and then in Noida due to efforts of Delhi State Tobacco Control Cell," he said.

According to the Centre for Disease Control and Prevention (CDC), most ecigarettes contain nicotine, which is addictive and toxic to developing fetuses.

Nicotine exposure can also harm adolescent brain development, which continues into the early to mid-20s. The report mentioned that these e-cigarettes aerosol can contain chemicals that are harmful to the lungs.

Therefore, US FDA has not approved e-cigarettes/vape as cessation device yet. Dr Arora said that some international companies are soon launching e-cigarettes which will run with batteries. These will contain traditional material of cigarettes, which will produce its effect through the heat of the battery.

"For iQOS (iQOS heats the tobacco just enough to release a flavourful nicotine-containing vapour but without burning the tobacco) devices, there are no long term studies on their safety profile and moreover such devices at the time of charging sometimes got burst which have resulted in serious injuries. These devices only become attractions for youngsters and entry of such products are going to create problems in implementing tobacco control activities," Dr Arora said.

Doctors said that people think that e-cigarettes act as a cessation device to quit smoking habit, however, they are unaware that it gradually develops a habit.

Recently, Delhi State Tobacco Control Cell slammed a senior professor of the North Eastern Hill University, Shillong for propagating the use of e-cigarettes.
