Canna-Tsu, Canna-Tsu, pretty, pretty, pretty pretty Canna-Tsu. This high CBD hybrid is a cross of Cannatonic and Sour Tsunami. Canna-Tsu has a mellow yellow citrus inhale, and earthy flavors that activate on the exhale. Because of its relaxing and clear CBD-heavy effects, Canna-Tsu is prized by patients to relieve inflammation, seizures, pain and anxiety.
