Horrible, because it can encourage use among underage kids (just like flavored cigarettes).
Lol at being worried about "underage kids" being stoned. Who cares? It's THC. So what if they think about Spongebob deeper and eat more cookies?
That's your opinion and I respect that.
However, my opinion is that during formative years, parents should be vigilant to ensure that kids aren't "high" during that time; there's a lot to learn, socially and academically, in those times, and being high just doesn't help matters. Plus, the risk of dependence is greater for younger people.
Note I didn't say edibles should be banned, just that they're not advisable.
