If regular Runtz is the hero of the cannabis world, then Black Runtz is the dark twin. This indica-dominant hybrid is a phenotype of classic Runtz, our 2020 Strain of the Year, and shares the same award-winning Zkittlez and 2018 Strain of the Year Gelato parents. Black Runtz is 24% THC, making this strain an ideal choice for experienced cannabis consumers. Leafly customers tell us Black Runtz effects make them feel relaxed, happy, and aroused.
