It has absolutely nothing to do with the taste of the candy cigarettes. Its the idea that they're getting cigarettes. You stand there with the candy stick in your mouth, sucking on it, taking small bites out of it so it looks like its burning away.
Why buy candy cigarettes when you can get laffy taffy, a chocolate bar, or pixie stix? Its the idea that you can look like the big kids or daddy who smoke, which eventually turns into them buying real cigarettes.
I'm not saying every kid who buys a pack of candy cigarette wishes its actual cigarettes, but you're trying to tell me "that Big Tobacco" didn't want candy cigarettes out there as an early incentive to a new group of costumers since they're current costumers seems to continually drop dead?
