A team of researchers at UC Berkeley figured out a way to manufacture tetrahydrocannabinol (THC) and cannabidiol (CBD) — both products derived from the cannabis plant — from specially bioengineered yeast, according to Wired. 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.
