3 types of weed

The Different Types of Weed: Sativa, Indica, Hybrid

Why the indica and sativa classifications actually don’t matter.

Consumers frequently recommend different types of weed based on the high they’re trying to achieve. “If you want an energetic high, go with sativa. Need help sleeping? Try an indica. A hybrid will give you the best of both worlds.”

While this sounds right based on our anecdotal experiences, the science behind this heavily believed fact isn’t all there. Choosing a cannabis product based on whether it is sativa, indica, or hybrid may not be a particularly helpful strategy.

Rather than in its physical features, science says the important distinctions between the different types of weed are the varying chemical compositions within each strain or individual plant.

Sativas vs Indicas vs Hybrids

Sativas

  • Origins: Sativas are believed to come from equatorial regions which explains their preference for tropical growing conditions.
  • Physical Features: Sativas are thin and quite tall, scaling 12 feet or higher. Their leaves are serrated and long.
  • Strains: Green Crack, Sour Diesel, and Durban Poison

Indicas

  • Origins: Indicas are believed to come from somewhere in India or Afghanistan, although the exact origins aren’t really known.
  • Physical Features: Indicas are known for their short, squat stature, ideal for surviving the volatile mountain climate from which they are thought to originate.
  • Strains: Hindu Kush, Girl Scout Cookies, Northern Lights

Hybrids

  • Origins: Hybrids are manually bred from both indica and sativa strains. Most cannabis strains are hybrids, but they may be indica or sativa dominant.
  • Physical Features: The aesthetics of a hybrid plant vary based on its parents.
  • Strains: Blue Dream, Gorilla Glue, Chemdawg

Terpenes are More Important than Strain Type

The most prevalent chemical constituents in a cannabis plant are cannabinoids and terpenes. Cannabinoids interact with the endocannabinoid system (ECS) in ways that produce physiological and psychological effects that are, for the most part, beneficial.

For this reason, when trying to decide how a specific strain is going to affect you, it’s more beneficial to look at cannabinoid and terpene content than choosing based off of indica, sativa, or hybrid.

Cannabinoids

The most abundant cannabinoids in a marijuana plant include the following:

  • Tetrahydrocannabinol– THC is the most abundant cannabinoid present in most cannabis plants. It is primarily responsible for the plant’s psychoactive effects. While in small doses, THC can enhance mood, larger doses have been implicated in adverse effects including paranoia and anxiety. Cannabis products with high THC content are more likely to lead to these negative side effects.
  • Cannabidiol– CBD is the second most abundant cannabinoid in marijuana, and it has been the subject of extensive research in the past decade. CBD is a primary agent in cannabis’ medical efficacy, but it does not cause any psychoactive effects. CBD’s side effects are relatively mild making it a competitive medicine for pediatric patients as well as those managing chronic symptoms. Cannabis products containing elevated amounts of CBD are less likely to lead to side effects since CBD counteracts the adverse psychological reactions to THC.
  • Cannabinol– CBN research is limited, but existing evidence show that the non-psychoactive cannabinoid plays an important role in cannabis’ sedative effects. It also seems to work synergistically with CBD and THC in alleviating pain. Products with greater traces of CBN may be linked to greater sedation.

Terpenes In Cannabis

Terpenes are extremely volatile compounds that give cannabis (and other plants) its fragrance and flavor. Like cannabinoids, terpenes also interact with molecular pathways in the human body to produce primarily beneficial effects.

Some of the most frequently occurring terpenes in cannabis plants include the following:

  • Myrcene– Myrcene has been identified as an anti-inflammatory, analgesic, and sedative.
  • Caryophyllene– Typically the most abundant terpene in cannabis plants, caryophyllene is an anti-inflammatory, a gastric cytoprotective, and anti-malarial
  • Pinene– Pinene has been identified as a bronchodilator and an anti-inflammatory.
  • Linalool- Best known for its anxiolytic effects, linalool is also an anti-oxidant, anti-cancer, and antibiotic

Ethan B. Russo, renowned cannabis researcher, argues that the synergistic relationship between cannabinoids and terpenes is a far more useful indicator of medical efficacy than a cannabis plant’s species classification. In his seminal 2011 British Journal of Pharmacology review, “Taming THC,” Russo focuses on the potential for cannabinoid and terpenoid interactions to “produce synergy with respect to treatment of pain, inflammation, depression, anxiety, addiction, epilepsy, cancer, fungal and bacterial infections.”

If Russo is right, whether or not a cannabis product is suitable for morning or evening use depends on its cannabinoid and terpene composition, not its physical description (the primary factor used to classify a plant as either sativa or indica).

Weed 101: Sativa, Indica Effects Aren’t Based In Science

According to a 2014 essay by Jacob L. Erkelens published in Cannabinoids, the controversy surrounding cannabis taxonomy stems back to the 16 th century. Even then cannabis was classified with multiple names including wild hemp, domesticated hemp, Cannabis sylvestris, and Cannabis terminalem. It was Carl Linnaeus, the botanist credited with establishing the taxonomical system we use today, who formally classified the species as Cannabis sativa in 1753. A new species of Cannabis, C. indica, was formally classified in 1785 by French biologist Jean-Baptiste Lamark. In both cases, these classifications were based on the geographical origins and physical appearance of each species, not their chemical compounds.

In the 234 years since Lamark’s addition, hundreds of cannabis strains, or sub-varieties within the two broader species sativa and indica, have been identified. According to their producers, each of these strains possesses the potential to create a unique set of medicinal effects. While these names add complexity and interest to cannabis subculture (as well as a mechanism for producers to compete with one another), they present a significant debacle: their differences are not supported by research, primarily because high-quality research on the topic does not exist.

The number of patients turning to cannabis as legitimate medicine is growing, and often these people have little more than anecdotal evidence to turn to when considering the best cannabis products to consume. It is becoming an increasingly urgent priority to determine the chemical composition of individual strains and how these compositions (and in which doses) affect the human body.

For now, cannabis consumers do not have to settle for myth or ignorance. Legal marijuana states require manufacturers and producers to label their cannabis products. Rather than relying on the species of a cannabis plant to predict the effects they will experience, consumers should examine the cannabinoid and terpene content printed on the label of each individual cannabis product and study current research on the effects of those chemical compounds.

The three types of weed are sativa, indica, and hybrid. If you plan on trying cannabis, it's important you know their differences before you explore.

Indica vs. Sativa: What’s the Difference Between Cannabis Types?

Jump to section:

W hen browsing cannabis strains or purchasing cannabis at a dispensary, you may notice strains are commonly broken up into three distinct groups: indica, sativa, and hybrid. Most consumers have used two of these three cannabis types (indica and sativa) as a standard for predicting effects. Here’s what is generally accepted as true among cannabis consumers.

  • Indica strains are physically sedating, perfect for relaxing with a movie or as a nightcap before bed.
  • Sativa strains are energizing with uplifting cerebral effects that pair well with physical activity, social gatherings, and creative projects.
  • Hybrid strains are a balance of indica and sativa effects.

This belief that indicas, sativas, and hybrids 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.

But if you look at the chemical “ingredients” inside of indicas and sativas – that is, terpenes and cannabinoids (more on that below) – you’ll notice there aren’t clear patterns to explain why one type would be inherently sedating and the other uplifting. We know that indica and sativa cannabis strains can look differently, but this distinction is primarily only useful to cannabis growers.

To find a strain that will provide the desired effect, your best bet is to understand which chemical ingredients make up that strain. Using Leafly’s Cannabis Guide, you can rely on simple shapes and colors to visually understand what your favorite strains look like, chemically speaking. And when you use the chemical ingredients of a strain to guide your purchasing decision, you’re more likely to find the types of strains that agree with your body. You can learn more about how the Cannabis Guide works in this walkthrough.

In this article, we’ll explore how the words “indica” and “sativa” made it into the vernacular of cannabis consumers worldwide, and to what extent they’re actually meaningful when choosing a strain.

Indica vs. sativa effects: What does the research say?

The indica, sativa and hybrid system is no doubt convenient, especially when first entering the vast and overwhelming world of cannabis. With so many new strains and products to choose from, where else are we to begin?

A more useful starting point when thinking about the effects of strains would be cannabinoids and terpenes, two words you should put into your. back pocket if you haven’t already. We will get to know these terms shortly.

But first, we asked two prominent cannabis researchers if the 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 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.”

Raber agreed, and when asked if budtenders should be guiding consumers with terms like “indica” and “sativa,” he replied, “There is no factual or scientific basis for making these broad sweeping recommendations, and it needs to stop today. What we need to seek to understand better is which standardized cannabis composition is causing which effects, when delivered in which methods, at which specific doses, to which types of [consumers].”

What this means is not all sativas will energize you, and not all indicas will sedate you. You may notice a tendency for so-called sativas to be uplifting or indicas to be relaxing, especially when we expect to feel one way or the other. Just note that there is no hard-and-fast rule and chemical data doesn’t reflect a clear pattern.

What is hybrid weed?

Hybrid strains are bred from both indica- and sativa-descended plants. Due to the long history of crossbreeding cannabis strains—much of it historically done underground to evade authorities—strains that have pure indica or pure sativa lineages are rare. Most strains referred to as “indica” or “sativa” are, in fact, hybrids, with genetics inherited from both subspecies.

Examples of hybrid strains:

If Indica and Sativa aren’t predictive of effects, then what is?

The effects of different strains of weed depend on a number of different factors, including the product’s chemical profile, your unique biological tolerance, dosage and consumption method. It also depends on the cannabinoid profile and terpenes of the strain. If you understand how each of these factors change the experience, you’ll have the best chance of finding a strain that is perfect for you.

Cannabinoids

The cannabis plant is composed of hundreds of chemical compounds that create a unique harmony of effects, which is primarily led by cannabinoids and terpenes. Cannabinoids like THC and CBD (the two most common) are the main drivers of cannabis’ therapeutic and recreational effects.

  • THC( Δ9-tetrahydrocannabinol ) makes us feel hungry and high, and relieves symptoms like pain and nausea.
  • CBD( cannabidiol ) is a non-intoxicating compound known to alleviate anxiety, pain, inflammation, and many other medical ailments.

Cannabis contains dozens of different cannabinoids , but start by familiarizing yourself with THC and CBD first. Instead of choosing a strain based on its indica or sativa classification, consider basing your selection on these three buckets instead:

  • THC-dominant strains are primarily chosen by consumers seeking a potent euphoric experience. These strains are also selected by patients treating pain, depression, anxiety, insomnia, and more. If you tend to feel anxious with THC-dominant strains or dislike other side affects associated with THC, try a strain with higher levels of CBD.
  • CBD-dominant strains contain only small amounts of THC and are widely used by those highly sensitive to THC or patients needed clear-headed symptom relief.
  • Balanced THC/CBD strains contain similar levels of THC and CBD, offering mild euphoria alongside symptom relief. These tend to be a good choice for novice consumers seeking an introduction to cannabis signature high.

It’s worth noting that both indica and sativa strains exhibit theses different cannabinoid profiles. “Initially most people thought higher CBD levels caused sedation, and that CBD was more prevalent in indica cultivars, which we now know is most definitely not the case,” Raber told Leafly.

Terpenes

If you’ve ever used aromatherapy to relax or invigorate your mind and body, you understand the basics of terpenes. Terpenes are aromatic compounds commonly produced by plants and fruit. They can be found in lavender flowers, oranges, hops, pepper, and of course, cannabis. Secreted by the same glands that ooze THC and CBD, terpenes are what make cannabis smell like berries, citrus, pine, fuel, etc.

One question yet to be answered by research is how terpenes- and different combinations of those terpenes – shape the effects of different cannabis strains.

“Terpenes seem to be major players in driving the sedating or energizing effects,” Raber said. “Which terpenes cause which effects is apparently much more complicated than all of us would like, as it seems to [vary based on specific] ones and their relative ratios to each other and the cannabinoids.”

There are many types of terpenes found in cannabis, and it’s worth familiarizing yourself with the most common terpenes—especially myrcene, caryophyllene, limonene, and terpinolene, since they’re the most likely to occur in pronounced levels in cannabis.

Three sativas in the Cannabis Guide, all with very different cannabinoid and terpene profiles, meaning each will likely give different effects.

If you can, smell the cannabis strains you’re considering for purchase. Find the aromas that stand out to you and give them a try. In time, your intuition and knowledge of cannabinoids and terpenes will guide you to your favorite strains and products.

Biology, dosing and consumption method of cannabis

Lastly, consider the following questions when choosing the right strain or product for you.

  • How much experience do you have with cannabis? If your tolerance is low, consider a low-THC strain in low doses.
  • Are you susceptible to anxiety or other side effects of THC? If so, try a strain high in CBD.
  • Do you want the effects to last a long time? If you do, consider edibles (starting with a low dose). Conversely, if you seek a short-term experience, use inhalation methods or a tincture.

There are many factors to consider when choosing a strain, but if you find that indica strains consistently deliver a positive experience, then by all means, stick to what you know. However, if you’re still searching for that ideal strain, these are important details to keep in mind.

CBD vs THC in indicas, sativas and hybrids

Could it be that indica and sativa cannabis strains feel different because they produce different levels of THC and CBD on average? To find out, we used lab-sourced data to determine the average abundance of each cannabinoid across sativa, indica and hybrid strains (excludes CBD-dominant and balanced strains)

Taking the average THC levels across indica, sativa, and hybrid strains, we can see that THC-Dominant strains- regardless of their plant type – present approximately the same average and rage of THC. So it’s unlikely THC accounts for perceived differences between indicas, sativas and hybrids.

But are there any notable differences in CBD abundance for CBD-containing indica, sativa and hybrid strains?

Once again, there are very little differences on average between indica, sativa and hybrid CBD levels.

So if differences in cannabinoid profiles don’t tell the story behind the perceived differences of indica, sativa, and hybrid strains, you might wonder if there’s another chemical explanation.

Terpenes in indica, sativa, and hybrid strains

We know that terpenes are responsible for the different aromas found in cannabis and that, according to early research, they may deliver unique therapeutic effects. But to what extent do they make a strain energizing or sedating? And are there patterns that could explain why indicas and sativas sometimes feel different?

Let’s take a look at lab data illustrating terepne trends among indicas, sativas, and hybrids

Above, you’ll find the levels at which indica, sativa, and hybrid strains tend to produce common terpenes. They tend to present relatively similar patterns in terpene profiles with some interesting points of variation—one of which is terpinolene.

Terpinolene is a terpene found at high levels in only a small subset of cannabis strains, most of which are sativas and hybrids. Some terpinolene-dominant strains you’ve probably seen or heard of include Dutch Treat, Jack Herer, Golden Goat, and Ghost Train Haze. You’ll find terpinolene in many strains related to these, like Jack crosses (e.g., XJ-13, J1, Chernobyl) or Golden Goat hybrids (e.g., Golden Pineapple, Golden Ticket), indicating that there may be genetic consistency.

Still, a majority of sativa strains are not terpinolene-dominant. But if you’ve tried terpinolene-dominant strains in the past, you’ll have likely noticed they’re similar in effect. What this suggests is that strains with similar cannabinoid and terpene combinations may offer more reliable consistency in effects. Terpene profiles also allow us to deepen our understanding of potential variations within each cannabis type. Let’s take three hybrid strains for example—ACDC, Chernobyl, and OG Kush.

Although each categorically identify as “hybrids,” they’re vastly different strains on a chemical level. ACDC is a gentle CBD strain commonly chosen by those who are sensitive to THC and its anxious side effects. Chernobyl is a blissful and uplifting strain that is preferred by many for daytime activities. OG Kush delivers a heavy-handed punch of euphoria that is commonly chosen by seasoned smokers or reserved for evening sessions.

Strain Name Strain Type THC CBD Helps with
Sour Diesel sativa 18.5% creativity, depression,
Green Crack sativa 17% energy, uplifting,
Lemon Haze sativa 19% fatigue, pain,
Candyland sativa 18.5% socializing, relaxation
Purple Punch indica 18.5% stress, euphoria
Pennywise indica 7% 8% relaxation, anxiety,
Northern Lights indica 11% inflammation, pain,
GMO Cookies indica 24% pain, insomnia,
Bubba KushBubba Kush indica 17% appetite, pain,
GG4GG4 hybrid 20% insomnia, stress,
Harle-Tsu hybrid 9% stress, relaxation,
Sherbert hybrid 18.5% stress, creativity,
Cannatonic hybrid 5.5% 10% pain, focus,
Blue Dream hybrid 16% relaxation, euphoria,

By going a step beyond their indica, sativa, or hybrid classification to consider cannabinoids and terpenes, you’re more likely to identify the specific strains you like or don’t like.

Indica and sativa: Origin and evolution of the terms

The words “indica” and “sativa” were introduced in the 18th century to describe different species of cannabis: Cannabis sativa and Cannabis indica. The term sativa described hemp plants found in Europe and western Eurasia, where it was cultivated for its fiber and seeds. Cannabis indica refers to the psychoactive varieties discovered in India, where it was harvested for its seeds, fiber, and hashish production.

Although the cannabis varieties we consume largely stem from Cannabis indica, both terms are used—even if erroneously—to organize the thousands of strains circulating the market today.

Here’s how terms have shifted since their earliest botanical definitions:

  • “sativa” refers to tall, narrow-leaf varieties of cannabis, thought to induce energizing effects. However, these narrow-leaf drug (NLD) varieties were originally Cannabis indica ssp. indica.
  • “indica” has come to describe stout, broad-leaf plants, thought to deliver sedating effects. These broad-leaf drug (BLD) varieties are technically Cannabis indica ssp. afghanica.
  • “hemp” refers to the industrial, non-intoxicating varieties harvested primarily for fiber, seeds, and CBD. However, this was originally named Cannabis sativa.

With the mass commercialization of cannabis, the taxonomical distinctions between cannabis species and subspecies got turned on its head and calcified. But now that you understand that there’s more to a strain than its indica, sativa, or hybrid designation, it’s worth thinking about how to shop for the right strain on your next dispensary visit.

How to shop for cannabis without saying ‘indica’ or ‘sativa’

What’s important to you as a cannabis consumer shopping for a specific mood has everything to do with potency, dose, and chemical profile (i.e., cannabinoids and terpenes). That’s the beauty of the Leafly Cannabis Guide – it allows you to easily identify which strains are chemically similar, so you have a better chance of finding (or avoiding) particular chemical profiles.

Let’s say you’re prone to anxiety and looking to avoid an uncomfortable, racy experience. If you tell a budtender you hate sativas because they make you anxious, they may hand you a THC powerhouse like White Fire OG simply because it’s not a sativa. Meanwhile, a “sativa” like Harlequin—with low levels of THC and high levels of CBD—might actually be a better fit.

Although it isn’t as simple as grouping strains into the indica-sativa-hybrid triumvirate that has long been our compass while navigating menus, try using potency to guide you. You may find that a strain packing 25% THC isn’t as enjoyable as that very fragrant strain tapping in at 16%, or the balanced THC/CBD variety that provides 10% of each cannabinoid.

You might also find that you gravitate toward strains that express similar terpene profiles. For example, if you like the terpinolene-dominant Jack Herer, you’ll likely enjoy Golden Pineapple or XJ-13, which are also terpinolene-dominant. Finding the right strain for you requires a bit of trial and error. Still, if you’re new to cannabis, there are appropriate places to begin your search for that perfect experience.

Helpful beginner resources to get you started with cannabis:

Cannabis is a personal experience, and how you select it is, too. Understanding its nuances should help give you an alternative perspective on what qualities to look for in a strain. Some of you are happy to sit down with any strain, any time, and that’s okay. For others, this level of precision in strain selection is key to having a good experience—and feeling good is what cannabis is all about.

*Anyone using cannabis for medicinal purposes should only do so with the advice of a medical doctor. More research is needed to understand the exact effects, feelings and benefits of cannabis for pain management.
