So you smoke a cigarette and then flick it up in the air, and then cause a fire to increase and from that, you will create a dozen fire balls from which you can choose a trajectory path. Like you can make some of the balls go in an arc from the left, right or even above. But once the trajectory has been set, you cannot take control of those fire balls. Once they touch some solid object, they explode just like a C1 of Deidara. And after that, you can die from cancer.
