It certainly looks like a Cig for this fan art. Though Gintoki doesn't really smoke. He's been known to take a few puffs here and there but for the most part he's more of a sweets person. So you'd be more likely to see him with a lollipop, pocky, pickled seaweed or any other snack to keep himself busy. Ginpachi sensei of course goes the 'smoking' lolli route, lol.
