A conversation with Dr Ben Boyce, ranging widely over some of the fundamental issues of the field, from how societies decide what to label as a ‘drug’ (and what this means), to prohibition itself and how this happens, through to heroin prescribing as a harm reduction practice. Ben is a prison educator, activist and author. His first book, Dr Junkie, is an autobiographical account of his experiences with addiction, crime and the penal system. He also hosts the Dr Junkie Show podcast, where an alternate version of this conversation also appears as episode 109. More details of his work can be found here. You can read a couple of the papers referred to in the conversation here and here.
