Chris Motz and Michael Pauley welcome Dr. Bonnie Omdahl for a conversation about marijuana, Initiated Measure 27, and public health. Dr. Omdahl explores what medical science says about the effects of marijuana on brain development, mental health, and physical health. Chris and Mike share thoughts on the huge gap between the scientific reality of marijuana and public perceptions of the drug. A Gallup survey reports that 71 percent of Americans consider chewing tobacco to be “very harmful” to one’s health, but only 27 percent said the same about marijuana. Dr. Omdahl offers her prescription for what can be done to make cultural perceptions of marijuana better conform to reality.
