If a kid is going to read the warning label before he ingests the edibles, I would imagine he's smart enough to make the correct decision. This still puts a huge question in my mind, " Why aren't the parents more in tune with their kids atmosphere".
I was in Colorado about 8 months ago and the max THC per piece was 10mg (recreational) . Patients with medical cards had access to higher concentrates of edibles though, not to mention food comes in many sizes/pieces.
Funny, as an individual with "poor impulse control," ;-) I figure that most anyone eating candy that is not theirs, regardless of age, rarely stops to read, let alone look at, the label for any other reason than to tear it off.
