This strain is a hybrid, though the precise ratio of sativa to indica seems to be a mystery. OG Shark has a pungent earthy aroma, with tones of blueberry and diesel. The genetics are unknown, but based on its smell and taste it may descend from the original Blueberry and Diesel strains.
The high is largely cerebral, suggesting strong sativa genes, with powerfully upbeat euphoria, relaxation, and creativity.
It can treat a wide variety of problems: depression, headaches, lack of appetite, nausea, and insomnia.
