I guess I would need more info. For instance, what (if any) effect does it have on the meat? Is there sufficient research available to back it up? Not having seen this before, I guess I would also wonder if the drug is "secured" enough on thearrow so that it doesn't fall into a childs hands or something to that effect. I think the idea definitely has merit though, even though the inevitable arguement of too much advantage over the deer will no doubt rear its head. Not that thats a bad thing of course.
