Cannabis is a single species of flowering plant, though it has two primary varieties within that species, Indica and Sativa, whose effects differ.Indica strains tend to provide sedative or relaxing effects and are often used therapeutically to treat chronic pain, insomnia, muscle spasm, and anxiety. The genetics of indica strains often include a higher concentration of CBD than sativa strains, which contributes to its sedating effects as well as having less intense psychoactive effects. Some common indica cannabis strains include Northern Lights, Afghani, Blueberry, and Chemo.

Sativa strains come with more stimulating effects and are popular to use medically as an anti-depressant, for migraines, for chronic pain, for nausea, and to stimulate appetite. Sativas typically have a higher concentration of THC than indica strains, causing more intense psychoactive effects, increased alertness and energy in the mind, and feelings of optimism. The higher THC-concentration is also connected to increased anxiety in some cases. Common sativa strains include Sour Diesel, Durban Poison, Jack Herer, and Super Lemon Haze.
