By the time she was 25 years old, Leanne Barbee of Ohio was taking 20 pills a day. She was suffering from depression, anxiety, fibromyalgia and arthritis to name a few. The pain was so bad that her doctor put her on high doses of methadone. But when a new doctor refused to prescribe any more pain killers, she was forced to quit methadone cold turkey. She did so with the help of cannabis and lost 65 pounds in the process.
