"Also known simply as Blue Diesel, Blue City Diesel is a highly potent mix of Blueberry and NYC Diesel. It's an indica-dominant hybrid (40:60 sativa/indica ratio), but it delivers both mind and body effects. THC levels have been known to exceed 23%, making this one of the strongest strains available for patients in search of THC. CBD levels, on the other hand, are decided low, much less than 1%. This means this strain is not a good selection for patients whose symptoms require CBD. The high is a combination of euphoric and happy mental effects with a lazy, sleepy body buzz. Blue City Diesel is best used to treat chronic pain, anxiety, sleeplessness, and muscle spasms. It's effective at almost any time of day, though many find it most useful at night. Reports of adverse effects include dry mouth and dry eyes, while headaches and dizziness are also possible. This strain is found mostly on the West Coast and in Colorado, though it's popular enough that it likely appears on the black market in other parts of the United States."
