Health officials say most of the pediatric poisonings happen when a child finds marijuana-containing products such as candy, chocolate or baked goods left around a home.
"The majority of pediatric poisonings occur unintentionally. Marijuana edibles left lying around on the coffee table or next to snacks can easily fall into the hands of young kids," said Dr. Alexander Garrard, clinical managing director of the Washington Poison Center. "Children should be supervised, and marijuana edibles should be left up high out of reach of kids or locked in cabinets."
Public health officials say marijuana intoxication in children can lead to anxiety attacks, psychotic-like symptoms, seizures, and respiratory depression.
