Admittedly, it reminds me of "The Fairly Odd Parents".
Right or wrong? Oh...who knows? At a glance it does appear somewhat questionable, but I know 18 year olds that legally vape and still go out in public wearing t-shirts sporting similar imagery, and 48 year olds that love Fairly Odd Parents. As long as it's not being advertised on Nickelodeon, I don't see a problem.
Personally, the package would deter me from buying it, not because I have a moral objection, but because it looks too much like a damned box of bio-genetically enhanced cereal that I would never eat.
Really, the argument can be made for most styles of packaging. Decorate your bottle with aardvarks..."hey kids love aardvarks". Decorate it with a sci-fi theme, "hey kids love sci fi". Decorate it with pictures of fruit, "hey kids love fruit". Decorate it with Corvettes and Ferraris, "hey kids love Corvettes and Ferraris." Decorate it with a sparkly gold label, "hey kids love sparkly gold labels". Decorate it with Barbie...well OK that's inappropriate, kids already OWN that, but where does it end?
If you want to scream that something's inappropriate, there need to be clear cut guidelines laid out first. Have we done that yet?
