With the latest massacre carried out by a lone perpetrator in the USA, reasons are being sought in attempts to find some kind of reason behind these horrific killings. The gun culture in America and Hollywood's promotion of misogyny are at the forefront of these discussions. But very little is spoken about of the fact that all of these individual mass murderers were using certain types of prescription drugs. Dr Jeanne Stolzer talks to me about what she sees as a terrifying oversight into the analysis of these murders and the how the devestating effects of many highly profitable pharmaceutical prescriptions are being ignored.
