Professors Michelle Mello and Rob MacCoun are noted in this Washington Post article for their recent study on the dangers of marijuana edibles. 

In the places where marijuana is legal, more and more children are being accidentally exposed to their parents’ drugs, a new study found.

The good news is that it is still rare for children to be exposed to marijuana when they are younger than 6 — but the trend is not exactly heading in the right direction.

…

In a recent editorial in the New England Journal of Medicine about the marketing of marijuana edibles to children, two Stanford University professors, Robert J. MacCoun and Michelle M. Mello, explained why edibles pose such a serious potential problem when it comes to the safety of children. “Whereas consumers commonly assume that a candy bar constitutes a single serving, some of these products contain four or more times the level of tetrahydrocannabinol (THC) that is considered to be a safe dose,” they wrote. “(Colorado, for instance, set a standard size for an edible serving at no more than 10 mg of THC.) At high doses, THC can produce serious anxiety attacks and psychotic-like symptoms. This problem is augmented by differences in the pharmacokinetic and metabolic effects of marijuana when it is ingested rather than smoked.”
