The two main types of cannabis, sativa and indica, are used for a number of medicinal and recreational purposes.
Sativas are known for their “head high,” an invigorating, energizing effect that can help reduce anxiety or stress and increase creativity and focus.
Indicas are typically associated with full-body effects, such as increasing deep relaxation and reducing insomnia.
Although research examining these effects is limited, it appears these plants have more in common than previously thought.
Many in the cannabis industry have moved away from the terms Indica, Sativa and hybrid and started classifying the different “strains” or, more correctly, “chemovars” as:
- Type I: high THC
- Type II: THC/CBD combined
- Type III: high CBD
More and more, the cannabis industry is moving away from the term “strains” and using chemovars (chemical varieties) instead, since the word “strain” is often used to refer to bacteria and viruses.
In other words, the category, or type, of cannabis may not be the greatest indicator of the effects you’ll experience.
Here’s how to find the right plant for your needs, strains to consider, potential side effects, and more.
The often-applied rule of thumb is that sativas are more invigorating and energizing, while indicas are more relaxing and calming — but it isn’t really that simple.
Individual plants produce varying effects, even among the same type of cannabis. It all depends on the plant’s chemical composition and the growing technique used.
Instead of looking at the type alone — sativa or indica — look at the description the grower and dispensary provide.
Oftentimes, the plant types are broken down into specific chemovars, or breeds.
Chemovars are distinguished by their individual cannabinoid and terpene content. This “cannabinoid profile” will provide the user with the best information to help them determine which chemovar is best suited for them.
Relying on names does not provide the user with the necessary information to pick the correct profile. These compounds are what determine the chemovar’s overall effects.
Cannabis plants contain dozens of chemical compounds called cannabinoids.
These naturally occurring components are responsible for producing many of the effects — both negative and positive — of cannabis use.
Researchers still don’t understand what all of the cannabinoids do, but they have identified two main ones — tetrahydrocannabinol (THC) and cannabidiol (CBD) — as well as several less common compounds.
- THC. THC is the main psychoactive compound in cannabis plants. It’s responsible for the “high” or state of euphoria associated with cannabis use. Levels of THC have been increasing as growers try to create hybrids with a greater concentration of the compound.
- CBD. CBD is non-impairing or non-euphoric. It doesn’t cause a “high.” However, it may produce many physical benefits, such as reducing pain and nausea, preventing seizures, and easing migraine.
- CBN. Cannabinol (CBN) is used to ease symptoms and side effects of neurological conditions, including epilepsy, seizures, and uncontrollable muscle stiffness.
- THCA. Tetrahydrocannabinol acid (THCA) is similar to THC, but it doesn’t cause any psychoactive effects. Its potential benefits include reducing inflammation caused by arthritis and autoimmune diseases. It may also help reduce symptoms of neurological conditions like Parkinson’s disease and ALS.
- CBG. Cannabigerol (CBG) is thought to help reduce anxiety and symptoms of obsessive-compulsive disorder, post-traumatic stress disorder, and depression.
A great deal of attention is paid to the amount of THC and CBD in a given strain, but newer research suggests that terpenes may be just as impactful.
Terpenes are another naturally occurring compound in the cannabis plant.
The terpenes present directly affect the plant’s smell. They may also influence the effects that specific strains produce.
According to Leafly, common terpenes include:
- Bisabolol. With notes of chamomile and tea tree oil, the terpene bisabolol is thought to help reduce inflammation and irritation. It may also have microbial and pain-reducing effects.
- Caryophyllene. The peppery, spicy molecule may help reduce anxiety, ease symptoms of depression, and improve ulcers.
- Linalool. Linalool is said to help improve relaxation and boost mood with its floral notes.
- Myrcene. The most common terpene, this earthy, herbal molecule may help reduce anxiety and insomnia so you can sleep better.
- Ocimene. This terpene produces notes of basil, mango, and parsley. Its primary effects may include easing congestion and warding off viruses and bacteria.
- Pinene. As the name suggests, this terpene produces an intense pine aroma. It may help boost memory, reduce pain, and ease some of the not-so-pleasant symptoms of THC, such as nausea and coordination problems.
- Terpinolene. Cannabis with this compound may smell like apples, cumin, and conifers. It may have sedative, antibacterial, and antifungal properties.
- Limonene. Bright, zippy citrus notes come from this terpene. It’s said to improve mood and reduce stress.
- Humulene. This terpene is deeply earthy and woody, like hops or cloves. Cannabis strains with this molecule may help reduce inflammation.
- Eucalyptol. With notes of eucalyptus and tea tree oil, this molecule is refreshing and invigorating. It may also help reduce inflammation and fight bacteria.
