Black Tuna was created by 5 Star Organic in order to provide patients with a powerful hit of THC that is beneficial for chronic pain relief. It is a British Columbian stain made by crossing Lamb’s Bread and Herojuana and is extremely popular in Canada not only for the strong narcotic effect it provides but also for its quirky marketing tactics as this was sold in sealed tuna cans. Flowers of this marijuana strain are compact, covered in trichomes and carry a strong smell. The color of Black Tuna is rich sage green with shades of darker green and also hints of purple. However, this strain does not smell like fish. In fact, the name originates from Black Tuna Gang that was well-known for the smuggling of Colombian marijuana in the 1970s in the United States. With a THC level of 34.28% percent, it is a potent strain and may be a bit too much for a beginner or moderate users.
