Most people chase the highest Tetrahydrocannabinol (THC) percentage they can find, but here's what the science actually shows: terpenes might be doing more of the heavy lifting than you think. Research from the University of Arizona Health Sciences found that terpenes amplify pain-relieving effects when combined with cannabinoids without increasing side effects. That's the entourage effect in action, where aromatic compounds work together to enhance therapeutic benefits beyond what THC delivers alone.
