And for weed it's more like high concentration of aromatic terpenes == eye watering yummy flavor == health and emotional benefits == also tends to have gobs of THC.
Different strains have different balances and varieties of terpenes and THC. I'd rather smoke "diet weed" with lots of terpenes but little THC, than "crack weed" with no terpenes and pure THC.

Pinene is my pungent favorite, which what makes Sour Diesel smell like a Royal Pine Air Freshener.

With a greater THC and terpene concentration, you can use a smaller amount of flower. For those who smoke, this means less of the harmful burned vegetable matter.
Even in a vaporizer, you get a nicer flavor and can use less.
