By injecting cannabis sativa plant genes into common brewer's yeast, which is the stuff that turns sugars into alcohol during the beermaking process, the yeast started spitting out cannabinoids as well, including THC — the psychoactive one — and CBD. In other words, the breakthrough could lead to beer that gets you high. ## Sticky Business It could also be a big deal for the environment. Planting, growing, and harvesting cannabinoids from large numbers of cannabis plants isn't as energy efficient as simply cultivating yeast. One [2012 study]() suggested three percent of California's total electricity usage was used to grow cannabis — a staggering figure. The process could even prove to be more reliable: "For the consumer, the benefits are high-quality, low-cost CBD and THC: you get exactly what you want from yeast," said Jay Keasling, a UC Berkeley professor, [in a statement](). "It is a safer, more environmentally friendly way to produce cannabinoids." ## Brewing Pot Enzymes inside the yeast first produce CBDA and THCA, which are precursors to CBD and THC, respectively. Once those substances are heated up, you've got CBD and THC — the same thing that happens when you light a joint or bake weed brownies. The process is simpler than growing a plant, and could even allow for just producing CBD. "Being able to produce that in a way that's uncontaminated with THC is a pretty valuable thing," said Keasling. **READ MORE:** [Forget Growing Weed—Make Yeast Spit Out CBD and THC Instead]() \[*Wired*\] **More on cannabis:** *[Legal Marijuana Could Threaten the Alcohol Industry, Says Report]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
