California Governor Jerry Brown has signed into law a measure to let doctors prescribe drugs to help dying patients end their lives. California is the fifth state to legalize assisted suicide. The move comes after “right-to-die” advocate Brittany Maynard took her own life last year at the age of 29 while suffering from an aggressive form of brain cancer. She had moved from California to Oregon to benefit from Oregon’s right-to-die law, which the California measure was modeled on.
