Black Tuna is named after the Black Tuna gang infamous for smuggling in marijuana to the United States from Columbia. Famous in Canada for the related marketing and prepackaging medication in sealed tuna cans, buds are covered in trichomes. Because of its high levels of THC, Black Tuna is not for the novice user, but is ideal for relief from chronic pain.
