Trainwreck is a cultivar with mysterious origins. Legend has it Trainwreck was so named because the original cut grew on a hill the same summer there was a train crash in the Humboldt region. Other sources claim the strain was named for the immediate slam of mental invigoration it had on users, which hit the mind like a runaway train. Trainwreck first emerged sometime in the 1980s from the Emerald Triangle region of Northern California, thought to be a cross of Mexican Sativa, Thai Sativa, and Afghani Indica.
