With news stories and opinion pieces popping up daily about medical marijuana legalization, dad Brandon Krenzler and his 7-year-old daughter, MyKayla Comstock, appeared on HuffPost Live this week to discuss what happens when a minor needs the drug. MyKayla has Leukemia and started taking it shortly after she was diagnosed. Currently, medical marijuana is legal in 18 states and in Washington D.C. However, as Valerie Vande Panne wrote in the Boston Globe, many parents are afraid to ask their children’s doctors for the drug, despite support from lawmakers. In a heartbreaking piece, HuffPost blogger Suzanne Leigh, a mother who lost her own child to cancer, spoke about some of the anxiety she felt around the issue. Ultimately, Leigh decided to buy marijuana for her 11-year-old, but she knew other moms and dads who would never consider using it to help their children with cancer. In the clip above, Krenzler says that when MyKayla was first diagnosed, cancer affected her in ways that were “terrifying.” “She was very sick, she was in a lot of pain … she was basically experiencing everything you wouldn’t want your daughter to experience,” he says. MyKayla adds that she was “really tired” all of the time. But now, she feels better. Though her doctor didn’t support her parents’ decision (dad says he looked at them like criminals), Krenzler is confident that he made the right choice for his daughter. If MyKayla wasn’t currently using medical marijuana, “her life would be riddled with illness, she would be sick every single day.” Watch the conversation above, and click here to view the full segment on kids and medical marijuana. via Medical Marijuana For Kids: Why I Give Cannabis To My 7-Year-Old (VIDEO).
