> I'd prefer that there was a regulation on these such that they were only available to adults, however. They can cause terrible injuries that require surgery in uninformed and impulsive children.

I agree. There seems to be a category of products that are definitely safe in the right hands, but they do look particularly "overly innocuous" and, while I don't think they should be banned, they should at least require some sort of "We're not kidding around, these can actually kill you" warning in big, bold letters.

A couple years ago I read about a teenager who died after ODing on caffeine powder he bought on Amazon. While there were lots of tasteless "Darwin award" comments when this happened, it's not hard to think that someone would think a spoonful of caffeine powder would be like a couple of NoDoz, instead of actually being like 30 cups of coffee.

Seems like there is a middle ground between outright banning these products and completely unregulated sales of potentially dangerous items like this.
