Runtz, also known as "Runtz OG," is a hybrid marijuana strain. Runtz is made by crossing  Zkittlez with Gelato and it is loved for its incredibly fruity flavor profile that smells just like a bag of the  candy we all know and love. Runtz is celebrated for its creamy smoke that is smooth and welcoming. This strain of weed produces euphoric highs and uplifting effects that are known to be long-lasting.
