Blueberry AK, as the name implies, is a cross between the indica-dominant Blueberry and the sativa-dominant AK-47, both popular and strong strains in their own right. Blueberry AK has a strong musky odor with berry undertones, with tastes ranging from sweet Kush to the peppery AK taste. People have used this mixture to treat anxiety, despair, and pain since its effects are both calming and uplifting, frequently resulting in a case of the giggles.
