a medical cannabis growers group in Vancouver, British Columbia, Canada, crossed Herojuana, a very strong flavored cannabis strain that provides great body-numbing effects, and Lamb's Bread. The origins of the Lamb's Bread plant comes from Jamaica, and it has been reported that even Bob Marley himself has encountered this wonderful slice of cannabis genealogy, whose effects have been known to give mass amounts of energy and positive introspection.
By crossing the two strains, 5 Star Organic created the "Black Tuna Cannabis Strain™". it gained quite a bit of fame in Canada for both its strong narcotic effect and its whimsical marketing—prepackaged meds were sold in sealed tuna cans. Flowers are compact,trichome-covered, and have a strong smell. Given its potency and high THC, this strain may be too much for novice or moderate users.
