Simon Erridge is an honorary clinical research fellow and doctor at Imperial College London, who holds a BSc with honors in Surgery and Anesthesia. He has a wide research portfolio with a specialist interest in cannabis-based medicinal products, recently publishing a paper on patient and public perceptions of medical cannabis for pain, nausea and vomiting after surgery. Simon joins me to speak about some of the research on medical cannabis and how it interacts with certain disorders, particularly ADHD.
