Buy Banana OG Pre-roll Joint Online. A lineage of giants – a bit Kush, part Haze, and traces of Skunk – Banana OG is not your average loaf. Subtle notes of sweet melon and under-ripe banana on the nose, but upon taste the classic sweet earth and dank hash flavour comes through, courtesy of its OG Kush heritage. Banana OG is as pungent as it is potent, and as its lineage suggests, is a cultivar for lovers of legacy genetics.
