In this episode of Science Actually, Katie Addy discusses drugs of abuse and their potential health benefits with our guest Dr Balázs Szigeti. Balázs is a researcher at the Centre for Psychedelic Research at Imperial College London. He has a background in computational neuroscience and started a collaboration with the Global Drug Survey to quantitatively compare the dose of recreational users of various drugs such as MDMA with the scientific literature. Balázs tells us a bit about his research into MDMA and psychedelics. He explains the difficulty of researching drugs of abuse, their potential benefits to people suffering with mental health disorders and the difficulty in regulation of such drugs. He also tackles our main question: can drugs of abuse have health benefits?
