Teens are genetically programmed to engage in risky behavior, it's a very old evolutionary adaptation. I don't think you or anyone else is ever going to be able to change that.
Also, teenagers are easy to influence through ads and eager to mimic cool characters in entertainment and what not. That makes them more likely to be influenced by both advertisement and lack of it.
Teenagers being somewhat more likely to take risk then equivalent single person of older age does not imply that the amount and kind of their risk taking is constant through human history and will not change as adults change their behavior.
1 write all the downsides on the packaging similar as for cigarettes
2 do not allow products that target children, I am referring to products with bright colors and candy aromas etc
I believe that the society can do a difference, it is true that some kids will use drugs, alcohol but those will usually have a problem at home, what we need to stop is having regular kids using e-cigarettes because they think are safe and cool.
the wide range of flavors is one of the main reasons that vaping is an effective smoking cessation tool for me and many other adults. please do not advocate banning flavors.
