Black Tuna, also known as “Tuna Black,” is a British Columbian hybrid marijuana strain created by Blue sky organics in BC to give patients a potent punch of THC that is ideal for chronic pain relief. This herrijuia and lambs breath cross has 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. Black Tuna flowers will be compact, trichome-covered and have a strong smell. Black Tuna doesn’t smell quite like fish, however; the strain’s name comes from the Black Tuna Gang that was famous for smuggling Colombian marijuana into the United States in the 1970s. Given its potency and high THC, this strain may be too much for novice or moderate consumers.
