Indica versus sativa: Everything you never wanted to know

The world of cannabis can often be confusing and intimidating. Here at The Rocky Mountain Collegian’s cannabis section, we often write articles that attempt to simplify and clarify these sticky details for the layman. This is not one of those articles. This will leave you more confused.

To begin with, cannabis flower comes from the cannabis plant. Cannabis plants are selectively bred for certain traits — often how they look, smell or make you feel. The cannabis flower that can be purchased in dispensaries is derived from generations of crossbred strains. The names often reference their lineage, though there are no established rules for naming strains.


Broadly, these strains fall into three categories: indica, sativa and hybrid.

Indica-strain buds are often characterized by their dark color, bushy appearance and earthy smell. These strains are more likely to produce a sleepy, “stoned” effect when used. A common mnemonic device is “in-da-couch,” referring to the lethargy the user experiences. It’s generally medically recommended for insomnia, chronic pain or low appetite. It’s recreationally recommended for video games, movies or going to sleep really fast.

Sativa strains are usually defined in opposition to indica: They may have a lighter, almost yellow color. They may make you feel euphoric, energized and talkative. A commonly made distinction is that indica provides a “body high,” while sativa provides a “head high” and is good for exercise, hiking or household chores.

“Personally, I don’t really call it (energizing) because THC’s not a stimulant like caffeine or anything,” said Thomas, a budtender at Elite Organics who asked that I only use his first name. “But typically, when you smoke a sativa, it’s not going to make you as tired as an indica.”

Hybrids are strains created by crossbreeding indica-dominant and sativa-dominant strains. They have varying effects, so it’s best to consult whoever gave it to you on what it’s supposed to do. They are generally classified as more of one or the other.

Here’s the thing about sativa and indica: While the cannabis industry goes to great lengths to make this all sound quite scientific, it’s actually not. These names are abstract terms that come from an often misunderstood scientific history.

This subject is still debated in the halls of botanical science. Are C. sativa and C. indica really different plants or the same plant adapting to different environments?”

“Everything, technically based on genetics and chemistry, is hybridized,” Thomas said. “Genetics are all very subjective … There hasn’t been any study to prove these things as a fact.”

He’s right — the genetics of cannabis in a post-prohibition world have become impossible to untangle. Human beings have apparently been using cannabis since long before recorded history. It was officially classified by Carl Linnaeus (the guy credited with inventing modern taxonomy) as Cannabis sativa in 1753, from the Latin “sativum,” meaning “cultivated,” and the Greek “kannabis,” meaning “that weed stuff that gets you high.”

A few decades later, Jean-Baptiste Lamarck came into some cannabis from India, which he noticed had darker and more broad leaves and grew significantly shorter. He determined that this was a separate species and called it Cannabis indica. Keep in mind, Lamarck also believed that giraffes evolved long necks by stretching really hard over time.

This subject is still debated in the halls of botanical science. Are C. sativa and C. indica really different plants or the same plant adapting to different environments? Regardless, this doesn’t matter either.

However you taxonomically classify the plants, present-day North American cannabis has been crossbred, interbred and thoroughbred into an unrecognizable freak of nature. Much like corn or watermelon, we’ve genetically engineered it to our purposes to be larger than any naturally occurring plant.

All this to say indica and sativa are basically meaningless terms with no connection to their original scientific meaning. These are subjective judgments made by people who tried the product themselves.

“Technically, I don’t think it’s a good classification; it’s just what’s used right now,” Thomas said.

If you ever find yourself in a dispensary, or more likely at the home of an acquaintance, and you feel like being a fun-sucking drip, tell them about all the stuff you learned in the paper. Or simply ask, “Do you feel like this is more of a daytime weed or a nighttime weed?” and use your snoofer to guide you. If it smells good, you’ll probably vibe.

Hayden Hawley, Cannabis Director
Hayden Hawley is the cannabis director for The Rocky Mountain Collegian. He is a fourth-year journalism major from El Cajon, California. He is also minoring in film studies and history. This is his first year working with The Collegian Hawley hopes that through the cannabis section he can help remove the taboo surrounding the cannabis industry and promote safe and informed cannabis use throughout the Colorado State University campus. He strives to provide honest and unbiased content that reports both on the joys of cannabis as well as its ever-growing social and environmental impacts. In his spare time, Hawley can be found doom-scrolling Twitter or watching A24 movies. His favorite way to enjoy cannabis is a bowl of freshly ground indica in a pipe or joint accompanied by a cold LaCroix and a box of Cheez-Its (not sponsored). Hawley has been interested in writing for his entire life. He enjoys baseball and birdwatching with his girlfriend. Before entering CSU, he was involved in standup and improv comedy, and he now hopes to continue writing for whoever wants to pay him after college ends. His experience of directing a section for The Collegian thus far has been rewarding and gratifying.
