A new study shows that edible marijuana may pose a special risk.
The research was conducted at a Denver hospital, where recreational cannabis is legal.
They found that there was a three-fold increase in emergency room visits due to edible marijuana.
While inhaled marijuana caused the most severe problems, researchers found that marijuana-infused foods and candies also led to trouble.
Patients went to the ER with symptoms such as repeated vomiting, racing hearts, and psychotic episodes.
