When browsing cannabis strains or purchasing cannabis at a shop, you may notice strains are commonly broken up into two distinct groups: indica and sativa. Most consumers have used these two cannabis types as a touchstone for predicting effects:
- Indica strains are believed to be physically sedating, perfect for relaxing with a movie or as a nightcap before bed.
- Sativa strains tend to provide more invigorating, uplifting cerebral effects that pair well with physical activity, social gatherings, and creative projects.
This belief that indicas and sativas deliver distinct effects is so deeply rooted in mainstream cannabis culture that budtenders typically begin their strain recommendations by asking you which of these three types you prefer.
However, data collected by cannabis researchers suggests these categories aren’t as prescriptive as one might hope—in other words, there’s little evidence to suggest that indicas and sativas exhibit a consistent pattern of chemical profiles that would make one inherently sedating and the other uplifting. We do know that indica and sativa cannabis strains look different and grow differently, but this distinction is primarily useful only to cannabis cultivators.
So how exactly did the words “indica” and “sativa” make it into the vernacular of cannabis consumers worldwide, and to what extent are they meaningful when choosing a strain?
Indica vs. Sativa Effects
This three-type system we use to predict cannabis effects is no doubt convenient, especially when first entering the vast, overwhelming world of cannabis. With so many strains and products to choose from, where else are we to begin?
“The clinical effects of the cannabis chemovar have nothing to do with whether the plant is tall and sparse vs. short and bushy, or whether the leaflets are narrow or broad.”
But first, we asked two prominent cannabis researchers if sativa/indica classification should have any bearing on a consumer’s strain selection. Ethan Russo is a neurologist whose research in cannabis psychopharmacology is respected worldwide, and Jeffrey Raber, Ph.D., is a chemist who founded the first independent testing lab to analyze cannabis terpenes in a commercial capacity, The Werc Shop.
“The way that the sativa and indica labels are utilized in commerce is nonsense,” Russo told Leafly. “The clinical effects of the cannabis chemovar have nothing to do with whether the plant is tall and sparse vs. short and bushy, or whether the leaflets are narrow or broad.”
