eli5, why do hand rolled cigarettes put out themselves, but a cigarette from a pack keeps burning?

Question

I had some really hard time phrasing that right but I hope y’all get my point.

If I light up a cigarette from a pack and leave it, it’ll keep burning, but the hand rolled won’t do the same, why?

In some countries, the government passed a law requiring cigarettes to go out after a few seconds if you don’t puff on them, to prevent fires. This happened over ten years ago in USA and it changed the flavor of the cigarette with the chemical they spray it with.
