Growing cannabis is a process that requires time, water and ultimately a lot of energy—and there’s plenty of room for error. Because the plant has become exponentially more potent (and popular) over the years, its make-up can often be difficult to understand. Cannabis has many active components, but the main two are THC (which gets you high) and CBD (a non-psychoactive anti-inflammatory). Extracting the two—separately and precisely—from cannabis plants is common, but complicated. Now researchers have genetically modified beer yeast to produce both cannabinoids. They can do so separately (drastically reducing the issue of contamination) and ultimately have the ability to revolutionize the cannabis industry, but at that point is it even cannabis?
