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 are making this one of the strongest strains available for patients in search of THC. 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.
