Strain

A medical cannabis strain refers to the specific variety of the cannabis plant used to produce cannabis-based medicines.  Strains, also known as cultivated varieties or cultivars, are defined by their chemical makeup, including cannabinoids, terpenes, and flavonoids, which can influence how a medicine may affect a patient.

What are the Main Medical Cannabis Strains?

Medical cannabis is commonly grouped into three main strain types: indica, sativa, and hybrid. These terms are based on the plant’s genetic and physical characteristics, as well as traditional associations with certain effects.

  • Indica varieties are typically associated with more relaxing or calming effects.
  • Sativa varieties are often linked with more uplifting effects, such as increased energy or focus.
  • Hybrid strains are created by crossbreeding indica and sativa plants and may share characteristics of both. Some hybrids lean more towards one type, while others offer a more balanced mix. Today, many medical cannabis products are hybrids due to years of selective breeding.

However, current scientific evidence suggests that these labels alone are not reliable predictors of how a cannabis product will affect an individual. Research shows that a product’s cannabinoid and terpene profile, rather than whether it is labelled indica or sativa, plays a much greater role in determining its potential therapeutic effects.

For this reason, clinicians at Curaleaf Clinic do not base treatment decisions solely on indica or sativa classifications. Instead, these terms may be used as a helpful starting point when discussing a patient’s goals, preferences, and previous experiences.
