You are missing the point. I am not against laws to restrict sales to minors. Although I do believe that perhaps coffee should be similarly restricted since caffeine and nicotine have more in common than not, but that is a side issue we should not go down.
The point I *AM* making is that we should not restrict these products when sold to adults, The "Elephant" argument is not about restricting sales to minors. It is about restricting sales to adults in order to prevent incidental use by minors evading the laws restricting sales to them.
Well, the original point that I was trying to get at, and I don't know if I did it well, is that the incidental laws that would affect adults are not going to be passed simply by virtue of children using something that they shouldn't. That's just a symptom. The real issue is that vaping might, and I think it will, increase the overall use of tobacco, starting with children that will go with them throughout life. This is one of the reasons we passed so many laws against cigarettes. This is one of the issues that the FDA is looking at when they are thinking about regulation. Because there is an increase in tobacco use due to vaping, as evidenced by how children are attracted to vaping, there is more justification to regulate. If the issue was simply that children do it, the best remedy, besides making it illegal, would be to restrict sales with age limits.
