Scientists resurrect ancient cannabis enzymes with medical promise

Scientists have uncovered how cannabis evolved the ability to make its most famous compounds-THC, CBD, and CBC-by recreating ancient enzymes that existed millions of years ago. These early enzymes were multitaskers, capable of producing several cannabinoids at once, before evolution fine-tuned them into todays highly specialized forms. By resurrecting these long-lost enzymes in the lab, researchers showed how cannabis chemistry became more precise over time-and discovered something unexpected: t...
