From components to working: All you need to know about e-cigarettes

What is an e-cigarette?
 

E-cigarette and Vape are electronic devices used for smoking. Instead of smoke from burning tobacco, an e-cigarette user inhales aerosol, commonly called vapour, produced from a combination of vape juice and atomiser (see below). Hundreds of varieties of vape juice (with and without nicotine) and e-cigarettes are there in the market, mostly imported from China. More sophisticated e-cigarettes might have features to control the vapour flow, heating, large liquid tanks and replaceable parts.

How it works?

On pressing the on/off button, the battery powers the coil which heats up the cotton that is soaked in vape juice. When a user inhales, the air travel from the air vents through the cotton up to the mouth piece. Cotton burning in vape juice, which may be flavoured and/or contain nicotine, produces the vapour

What do we know?

•  Hundreds of e-cigarettes from Chinese makers like Kanger Tech, SMOK and Eleaf easily make it to India through imports
• Health hazard from vaping hasn't conclusively been proved. There is lack of scientific research because vaping, as a phenomena, is only 3-5 years old 
•  Proponents sell vaping as an alternative to cigarettes, which are harmful, but studies show vapes also promote early smoking among teens 
• In the US, Michigan and New York have banned vapes. UK maintains it is safe
• With India banning vapes, Marlboro-owned Juul and Philip Morris won't be allowed to launch here
