In this episode, Chloe Burke and Saba Ishrat introduce you to the basics of Mendelian Randomisation. They talk about how and why Mendelian Randomisation is used in addiction research to look at causal relationships, as well as its limitations.   They speak to two experts in the field. First, Dr Anya Topiwala talks about her experiences of using Mendelian Randomisation, including research assessing the relationship between drinking and telomere length. And second, to Dr Robyn Wootton who talks about using Mendelian Randomisation in studying the relationship between mental health and substance use. The second interview also covers the potential pitfalls of Mendelian Randomisation, and some practical tips to avoid them.   Chloe and Saba have compiled a selection of open-access links below: Assessing and addressing collider bias in addiction research: the curious case of smoking and COVID-19.
