It's seeing cigarettes being stuck in your mouth by your role models. That's what encourages children to be the next generation of smokers. Not sure that e fags stop making smoking look acceptable to impressionable children.

I have mixed feelings about e fags. They contain addictive drugs so once PHE sponsored studies are completed, there will be a decision as to whether they remain freely open for sale or by prescription as a smoking cessation aid. (UK.)

On the other hand, they are an improvement for those in the vicinity of smokers.

Herbal tobacco is still unnecessarily something that irritates asthma and other bronchial condition sufferers and even the rest of us shouldn't have to move away to escape selfish people.
