Few strains come with as much widespread renown as Northern Lights, inarguably one of the most popular strains of all time. An inbred descendant of original Afghani landrace strains, Northern Lights is a pure indica. Northern Lights is a highly useful medical strain, effective at treating anxiety, pain, and insomnia, as well as lack of appetite. Cottonmouth is common, as are red eyes, while other negative effects are much more limited. This strain has a sweet, earthy flavor with hints of citrus.
