I think the word overdose is being misused here. Since there isn't a known lethal dose for cannabis, I'm thinking that these are cases of people not knowing just how potent the effects of edibles are, and freaking out. The term overdose doesn't really apply in the context of cannabis.
I should've put that in parentheses as I agree. the news uses certain words to make bunk news stories. they should try reporting on how many underage people die from driving drunk. won't happen till people start coming out and saying that they smoke pot besides the hippy.
