Dr Michael Mosley investigates how chronic pain treatments can lead to addiction, as well as meeting those such as Brenda who believes she couldn’t have functioned with her back pain for the past 15 years without regular doses of morphine. An eye-opener on how easily vital medicines can be abused. Ammar Kalia
