Dr. Sanjay Gupta, a neurosurgeon and CNN Chief Medical Correspondent, says that after researching the medical value of cannabis, he now believes it can benefit people with certain medical conditions.
In fact, sometimes marijuana is the only thing that works. Take the case of Charlotte Figi, who I met in Colorado. She started having seizures soon after birth. By age 3, she was having 300 a week, despite being on seven different medications. Medical marijuana has calmed her brain, limiting her seizures to 2 or 3 per month.
