A pure indica (sativa/indica ratio of 0:100), Blueberry Kush is a favorite offspring of two legends, Blueberry and OG Kush. It packs massive THC contents, topping 24% in at least one publicly available test. This strain contains much lower amounts of CBD, however, much less than 1%. That's too low to recommend Blueberry Kush as treatment for seizures and other conditions that respond to CBD. But it's a good strain for treating anxiety, low mood, ADHD, migraine headaches, mood disorders, chronic pain, and nausea. The indica effects are deeply relaxing, happy, euphoric, and sleepy. That makes Blueberry Kush a great late-night strain and an effective way to treat insomnia.
