Indica vs Sativa: What’s the Difference?


While browsing marijuana strains or purchasing medical marijuana from a dispensary, it’s common to see strains divided into three categories: indica, sativa, and hybrid.

Indica and sativa are two primary species of the marijuana plant, and cross pollination of these two species breeds hybrids. These general categories reflect the widely understood classifications of marijuana and have been used to distinguish the experiences associated with particular strains. However, there are much more important differences to consider.

With this in mind, these are the key distinctions largely accepted by marijuana connoisseurs:

Indica

  • Plants have shorter flowering cycles (6 to 8 weeks) and are able to thrive in colder climates native to the mountainous regions of Afghanistan, India, Pakistan, and Turkey
  • Plants are short in stature (2 to 6 feet) with wide, broad leaves and dense, plump buds
  • Strains often have higher levels of cannabidiol (CBD) and less tetrahydrocannabinol (THC)
  • Strains are commonly associated with relaxing and calming effects, while providing mainly a “body high”
  • Strains are usually consumed at night due to their sedating effects

Sativa

  • Plants have longer flowering cycles (10 to 16 weeks) and are able to thrive in warmer climates native to the tropical regions of Africa, Central America, and portions of West and Southeast Asia
  • Plants are tall in stature (8 to 15 feet) with long, thin leaves and airy, elongated buds
  • Strains often have higher levels of THC and less CBD
  • Strains are commonly associated with invigorating and energizing effects, while providing mainly a “mind high”
  • Strains are usually consumed during the day due to their stimulating effects

Hybrids are the result of crossbreeding indica and sativa plants and tend to be labeled as indica-dominant, sativa-dominant, or balanced. Hybrids are commonly grown to target specific effects, which are partly determined by the unique ratio of the two parent plants.

The three-category system used to predict marijuana effects is generally useful—especially for those new to the medical marijuana market. However, there is growing demand in the scientific community to abandon these categories and focus instead on a strain’s chemical composition to determine its potential effects.

The differences between indica and sativa do not serve as an accurate indicator for the effects experienced by a consumer.

Dr. Ethan Russo is a subject matter expert on the medicinal use of marijuana and currently resides as the Director of Research and Development at the International Cannabis and Cannabinoids Institute (ICCI)—a collective of global stakeholders from academia and private industries, committed to advancing medical marijuana research.

In 2016, Dr. Russo insisted that “accurate biochemical assays on cannabinoid and terpenoid profiles be available for [marijuana] in both the medical and recreational markets” and further claimed that “scientific accuracy and the public health demand no less.”

The differences between indica and sativa are rooted in each plant’s physical traits and attributes. However, these differences do not serve as an accurate indicator for the effects experienced by a consumer. As Dr. Russo suggests, the combination of chemicals in a plant is the superior predictive factor. These chemicals, which include THC, CBD, and hundreds of other cannabinoids are what distinguish a particular marijuana strain and its medical benefits.

As you explore medical marijuana and determine the right product for you, be sure to also consider the following:

  • Your desired effects. What do you intend to feel or treat? This question will help you pinpoint potential options. Discuss your goals with a dispensary employee, who may have recommendations to best suit your needs.
  • Your tolerance. With a variety of marijuana strains comes a variety of potencies. For first-time users, a low-THC and high-CBD strain may be the most tolerable and provide a less overwhelming experience. Start with a low dose. And if you desire stronger effects, increase your dosage or try experimenting with THC-dominant strains.
  • Your medical history. As with any medicinal remedy, there are potential side effects involved with marijuana. Before treatment, consult your doctor or other healthcare professional to identify possible interactions with your existing medical conditions and medications.
  • Your preferred consumption method. There are different ways to consume medical marijuana. In Pennsylvania, patients have the option to deliver product orally, topically, or by inhalation through vaporization. Each technique has its benefits and drawbacks. If you choose to vape, for example, you may experience effects quicker than if you were to use a transdermal (i.e., topical) patch.

Medical Marijuana Consumption Methods in Pennsylvania


In an industry where new products appear on the market daily, choosing the medical marijuana consumption method to suit your needs can be overwhelming. After selecting a strain for its desired effects, the next step is to consider which delivery method might work best for you. 

In Pennsylvania, medical marijuana patients can choose from three basic methods of consumption: inhalation (through vaporization), oral, and topical.

Inhalation

Vaporization

Vaporizers are growing in popularity among medical marijuana patients and health-conscious consumers. By using lower temperatures to heat marijuana, rather than burning it, vaporizers minimize exposure to the toxins associated with smoking. Additional research is needed to understand the health risks of vaporizing when compared to smoking.[1] However, consumers in one study reported less respiratory symptoms with vaping.

Vaporizers come in an array of makes and models but generally have cartridges that take marijuana oil or dry leaf. Oils and other concentrates are relatively new developments that provide relief using less product. However, they may have higher tetrahydrocannabinol (THC) levels than dry leaf, so it’s a good idea to start small and work your way up to the desired effect. 

Vaporization offers a level of discretion by producing less of an odor than smoking. The lower temperatures may also preserve the taste and produce stronger effects. When inhaling marijuana into the lungs, effects usually take place within minutes.

Oral

Oils

One simple way to get relief is by ingesting marijuana-infused products. In this process, cannabinoids are absorbed through the stomach and intestines. Because they undergo a chemical transformation during digestion, the effects caused by these products are often much stronger than any other consumption method.

Oils are concentrates that can be eaten, dispensed through a syringe and ingested, or taken in capsule-form. When orally ingesting any kind of marijuana product, it’s always a good idea to start with a low dose, be patient, and work your way up from there. It can take up to 2 hours to feel the effects, but they last anywhere from 4 to 6 hours—and sometimes longer!

Tinctures

There are also sublingual methods of delivery that completely bypass the digestive system.  Tinctures are marijuana-infused liquids that are usually placed directly under the tongue using a dropper or spray, although they may also be ingested. When products are administered sublingually, or under the tongue, cannabinoids are quickly absorbed into the bloodstream via the large number of blood vessels in that area. 

Dispensaries carry tinctures in a variety of dosages and cannabinoid profiles to suit your preferences and medical needs. Tinctures are an inconspicuous option that are odorless, offer better dosage control, and generally take effect within 15 to 60 minutes.

Topical

Topical products like lotions, balms, and salves can be applied to the skin for localized relief. Topicals are designed to treat pain, soreness, and inflammation, but they may also provide relief from things like skin conditions to itching. Topicals are non-intoxicating, which can make them great alternatives to products that are meant to be inhaled or ingested.

Because the cannabinoids in topicals don’t reach the bloodstream, they don’t produce the “high” feeling commonly associated with marijuana. Instead, cannabinoids like cannabidiol (CBD), cannabinol (CBN), and THC are absorbed into the skin, where they bind to a system of receptors located in and around the human body.

Onset time for topicals can range anywhere from a few minutes to a few hours, so be sure to read the label for details.

Patches

Transdermal patches are unique in that their properties penetrate through the skin to enter the bloodstream. They offer low-profile relief when applied to venous areas like the arm, wrist, or ankle. 

Patches come in a variety of cannabinoid profiles, including split ratios such as 1:1 CBN:THC—which has a sedative effect that may offer relief from insomnia. Patients can also opt for a simple, isolated cannabinoid like CBD to alleviate arthritic pain or inflammation, for instance. 

Although onset of effects is generally up to two hours, advances in slow-release technology can make patches a great option for relief that lasts all day or all night. 

At Calypso, we understand the world of medical marijuana can be an intimidating place, especially to new patients. But it doesn’t have to be. We hope this guide to Pennsylvania-approved consumption methods helps prepare you for your next dispensary visit so you can rediscover wellness.
