This potent favorite is hard to find, especially in the United States, but it’s popular throughout Canada, where it was born. The biggest selling point is its impressive THC concentration, with top levels easily exceeding 20%. CBD content is almost zero, so OG Shark shouldn’t be used for seizure disorders or other conditions helped by CBD. The 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. Negative effects likely include cottonmouth and red eyes.  It sells across that country but is most popular in Ontario, British Columbia, Alberta, and Nova Scotia. It occasionally sells in Washington State. Buy OG Shark marijuana online
