Blue Dream can be more than 20% THC but has a low CBD percentage, making this potent strain a fan favorite of both novice and veteran cannabis consumers. In terms of flavor, Blue Dream is reported to smell and taste like sweet berries. Medical marijuana patients often use Blue Dream to treat symptoms of stress, anxiety and depression.
