You're right, it's not, but it should be enough, is the point. It isn't the parents' responsibility to ensure the store's market their products responsibly, but it is the parents' responsibility to know what it is their kids are spending money on, consuming, etc etc. It's the parents job to protect their child, to monitor their consumption habits, etc etc. As parents, we are responsible for training and instilling morals in our children. It has nothing to do with the stores marketing responsibly.
And I also don't consider them putting these candies with the other candy to be irresponsible. It's a product that fits well in that aisle, where it's supposed to. Candy goes with candy, clothes go with clothes, hardware goes with hardware, etc. Yes, due to the nature of the product in question, morally they should consider putting it with other merchandise, if it's possible. In stores like Family Dollar or Dollar General, there are misc sections that they could be shelved at. But other stores don't have that luxury.
If a parent is with their kid and the kid happens to see it and asks the parent what it means, it's then that parent's responsibility to explain it to that child, if they've reached the point of being able to understand it all. I mean, let's face it, a 4 year old seeing that bag of candy vs an 8 or 12 year old seeing it... questions aren't gonna be asked until they get older and more curious. It's that curiosity that we either nurture and explain what it is, what it does, etc, or nip in the bud.
I guess my original intent was to stress that it's not the manufacturer's fault for creating a product that is inline with a practice that is becoming more and more widely acceptable. It's that particular store's fault for marketing it the way they are, in a state where marijuana is not legalized, in part or in full.
