Dr. Nehama Lewis joins us and reflects on how the media effects cannabis perception: "I would teach these classes on anti-drug campaigns and they would cover anti-marijuana campaigns and it never made sense to me why there wasn't a distinction made.We collected data in several projects now. The questions I always ask is how does exposure to media coverage of cannabis specifically say medical cannabis affect the way we think about cannabis more broadly and support for legalization? What interests me is the extent to which the public are being asked to make a distinction between medical cannabis that is being sold more heavily as a treatment and is being framed by the media as something good with an emphasis on the health benefits. There is a really good growing evidence base for that."
