Terpenes, in combination with cannabinoids, blend for specific therapeutic benefits and psychoactive results. Terpenes also determine the scent of specific strains. Depends on which receptors they are interacting with, terpenes can relax, energize, stimulate, or sedate the patient. When terpenes are blended with certain cannabinoids, growers and the engineers of specific strains can control the potency, activity, and feelings induced in the user. This makes for an ease of use and the possibility for all patients to find not only a comfortable strain but one that is tailored to the needs of their condition.
