The aroma and effect of a cannabis plant depend on its chemical profile, not simply on its category name. Strains bred from indica dominant seeds are frequently associated with terpenes such as myrcene, linalool, and caryophyllene, which produce earthy, floral, or peppery scents. Cannabinoid levels vary considerably from one cultivar to another, and some lines are selected for higher CBD content. Lab test results, where available, give a more accurate picture than general strain labels.
