Your argument holds zero weight/relevance in this discussion because you can not die from an overdose of marijuana. No, not even if you ate a 50 edibles. Not even if you smoked 15 blunts back to back.
People like to throw out the "hospitalized" statement all the time. Just because someone was taken to the hospital does not mean that they were ever in any actual danger. Someone's kid eats an edible and "feels funny" so they are taken to the hospital. Someone's kid eats a bottle full of Vicodin that they thought were candy and are taken to the hospital.. if you think those two things present the same danger to the child than I don't even know how to respond.
