 Electronic cigarettes or e-cigarettes and other electronic delivery systems are devices that heat a liquid to create an inhalable aerosol even containing nicotine. This presents specific challenges as jurisdictions determine how to regulate them. Hemant, welcome from our new Delhi partner studio. Hemant, how does one deal with e-cigarettes regime? Well, Tamara, a number of global tobacco control researchers have concluded that e-cigarettes are less harmful than combusted tobacco. However, the impact of e-cigarettes on public health is unclear. Studies from around the world suggest that the majority of adults using e-cigarettes are current cigarette users and some say that e-cigarettes are often motivated by a desire to quit using compostable cigarettes. However, there is evidence that some non-smokers including non-smoking youth are also experimenting with e-cigarettes. The World Health Organization and its Tobacco Control Arm, the Framework Convention on Tobacco Control as it is known as FCTC, a global treaty signed by more than 180 countries, have encouraged restrictions and bans on e-cigarettes since the earliest products began arriving on European and US shores way back in 2007. The WHO is a powerful influence on health and smoking policies in many countries, especially in poorer countries where the WHO fund programs employ many public health professionals. Official attitude towards or official approach towards e-cigarettes and nicotine use in general very widely. In the US, the FDA has authority over e-cigarette products but has spent the last eight years trying to create a working regulatory system. Whereas in the United Kingdom, e-cigarettes are essentially encouraged by the government health agencies because smoking creates a costly burden for the UK's national health service. The country stands to save money if smokers switch to e-cigarettes instead. Well, most other countries also allow a regulated market but are less enthusiastic in their endorsement of this practice. While in countries like Singapore, for instance, even mere possession of an e-cigarette is punishable. The evidence as I had mentioned earlier on the harms and benefits of e-cigarettes has not yet been clearly established or demonstrated. As the evidence base grows, we can expect additional activity in the regulatory regime.
