Indica, sativa and hybrid: what the labels really tell you.

Where the words come from

“Sativa” and “indica” began as botanical names in the 18th century. Over the next 200 years, botanists applied them inconsistently. Today’s shop-counter meanings (tall, energizing “sativas” and short, sedating “indicas”) grew out of that history. One cannabis taxonomist describes this everyday usage as totally misaligned with the formal botanical species.

“Hybrid” is used for plants bred from parents of both kinds.

What the research found

• Chemistry: a 2022 study looked at nearly 90,000 flower samples from six U.S. states, including California. Products labeled indica, hybrid and sativa were “highly intermingled” by chemical profile. The authors called marketing indica as sedating and sativa as energizing “specious.”
• Genetics: a 2021 study genotyped commercial samples and found no clear genetic clustering by label. The label seemed to track a small number of aroma compounds rather than ancestry.
• Strain names: a 2015 study found that 35% of samples sharing the same strain name were genetically closer to differently named strains than to each other.

In short, two products with the same label can be quite different, and two with opposite labels can be chemically similar.

What to look at instead

Researchers suggest describing cannabis by its measured chemistry, sometimes called its chemovar:

On a California label, that means checking:

• Total THC and Total CBD, and their ratio
• Other cannabinoids such as CBG or CBN, when listed
• Top terpenes, when listed. The 2022 study found that grouping products by their dominant terpenes separated them better than the indica/sativa label did.

Our guides to reading a label and to terpenes explain each of these.

How to use this when you shop

• Treat indica, sativa and hybrid as a rough hint about aroma and style, not a promise of how you’ll feel.
• Keep a note of the products you enjoyed, along with their THC, CBD and terpenes. Patterns in those numbers are more useful than the label.
• Effects also depend on the amount, how you consume it, your experience and the setting. Start with a small amount, especially with something new.
• Tell our team what you’ve liked before, and they can suggest products with a similar profile.
