Throughout Dr. Scott Bentz's career in emergency medicine, marijuana wasn't something he much worried about.
Perhaps a person a month would come in feeling panicky after smoking pot. A sedative and a quiet room usually did the trick.
"It's the easiest emergency medicine case you're going to see," said Bentz, the medical director of emergency services at Presbyterian/St. Luke's Medical Center in Denver.
And then came the day a man arrived in the emergency room so sedated and breathing so slowly after eating a marijuana-infused edible that he was nearly comatose.
