Two recent deaths and increased emergency room visits in Colorado have highlighted concerns about the safety of legal marijuana edibles.
Dr. George Sam Wang of Children’s Hospital Colorado says part of the problem is that the effects of edible marijuana begin more slowly than smokeable pot, though they tend to last longer.
“One of the dangers that we’ve been seeing with adult recreational retail use is they’ll take the recommended dose, wait, feel no effects and then continue to stack doses.
