Grapefruit is a longtime marijuana classic, a heady blend of the hybrid Cinderella 99 and a sativa bred specifically for its grapefruit flavor. With a sativa/indica ratio of 70:30, this strain packs a decidedly cerebral punch, with a major mood boost and intense euphoria. THC levels have been charted at 20%, so this is a pretty powerful strain. CBD levels, meanwhile, are very low, ruling this out as an effective treatment for epilepsy. But it’s highly effective at relieving anxiety and depression, as well as pain, GI distress, and PMS. The sweet taste and smell of grapefruit are dominant, thought there are also hints of other citrus fruits. Adverse effects are usually quite limited, though dry mouth and red eyes are possible.This strain is highly appealing to smokers looking for a strong head high.
