Not sure about tobacco, but there would be several ways to light something.
Pistols exist in the game, so it would be fair to extrapolate that a little magitek engineering could yield up something to throw up sparks. There are several references in the game that suggest that Eorzeans can harvest gases from Bomb monsters, too, for fuel. Now, you wouldn't likely have mass-produced lighters, but someone like Otto could afford one.
Fire Sprite cores are canonically used to heat things, as are Fire shards.
Also, any Thaumaturge ought to be able to snap fingers and produce a little flame on command.

"But in the laugh there was another voice. A clearer laugh, an ironic laugh. A laugh which laughs because it chooses not to weep."
