There is plenty of variety in most dispensaries of Indicas, sativas and hybrids.
Actually there is not. There is hybrids, hybrids, and more hybrids generally. The only pure genetics you get is an occasional afghanica. Pure Indcas don't get you high, pure Afghanicas don't yield (generally, there are exceptions to this), pure
sativas take too long to flower.
The descriptions of sativa, indica, and hybrid are getting outdated. My Casey Jones which is as close to a pure sativa that dispensaries will sell has a canabinoid profile of what people think of as an indica. My afghan kush profiles as a sativa. You've got kush plants with skinny leaves and jack herer crosses with fat leaves.
Sativa, Indica, and hybrid are better descriptions of how a plant grows than their medical effects.
