Explorer Bonnie Crystal and marijuana legalization advocate Billy Rogers discuss two groundbreaking topics that challenge conventional thinking. Crystal, a 21st century technologist and underground explorer, shares her discoveries from subterranean expeditions that reveal hidden aspects of our planet's geology and history. Rogers, campaign manager for Nevada's marijuana legalization initiative, explains the political and social forces behind efforts to end prohibition. The program examines how Nevada could become the first state to legalize recreational marijuana use for adults, allowing possession of up to three ounces for personal consumption. Rogers details the economic benefits of legalization while addressing common misconceptions about marijuana's effects compared to alcohol and tobacco. This dual presentation challenges listeners to reconsider both our planet's mysteries and outdated drug policies.
