Blue Dream is a sativa-dominant hybrid that has been recognized by consulting firm BDS Analytics as the most popular strain circulating in 2015 -- and with good reason. A cross of indica Blueberry and sativa Haze, it offers a universally appealing taste and a long-lasting, well-rounded high. Smokers enjoy the ideal balance of cerebral stimulation and physical relaxation. After enjoying a cult following in California, it has become a top seller in Colorado and Washington. Thanks to aggressive branding, it may soon find a home in newly legal east coast cannabis markets as well. Samples of Blue Dream have tested at between 15% and 25% THC.
