Though cannabis is biologically classified as the single species Cannabis Sativa, there are at least three distinct plant varieties (though the last is rare):
- Cannabis Sativa
- Cannabis Indica
- Cannabis Ruderalis
Different strains of cannabis contain different proportions of cannabinoids, terpenes, and other chemical compounds–and therefore have different effects on the body. When selecting a strain, it helps for the patient to know what type of effects they want to experience.
