In the final episode of a three-part podcast series, Christie Taylor explores some of the challenges and opportunities that cannabis presents for society, both now and in the future. One of the topics that Taylor examines is the possibility of growing cannabis compounds in labs, the need for cultivating the plant itself. This could offer a more efficient and consistent way of producing cannabinoids, the active ingredients in cannabis, for medical and recreational . Taylor talks to researchers who are working on developing methods to synthesize cannabinoids using yeast, bacteria, or algae. Another topic that Taylor discusses is the environmental impact of cannabis production, which is often or underestimated. Growing cannabis, whether legally or illegally, consumes a lot of water, energy, land, and fertilizers, and generates greenhouse gas and waste. Taylor interviews experts who are studying the ecological footprint of cannabis and looking for ways to make it more sustainable and less harmful to the planet.
