A person who lives their life for Cannabis, whether recreationally or medicinally. A true "cannabian" feels 4:20 pm arriving with enough foresight to roll a doobie in time. Cannabians like hemp ANY/EVERYTHING. They get the munchies and know exactly what combinations of Doritos, Chocolate Cupcakes and Strawberry milk will neutralize the cannabis and promote a sense of well-being that pharmaceuticals just cannot offer.
I am so Cannabian that my dorm voted me 'most likely to suck seeds'.
