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. This strain has an earthy flavor and aroma with notes of berries and herbs. Dry mouth and dry eyes are widely reported as side effects, while dizziness, paranoia, and headaches are less likely.
