Why does lighting a cigarette cause a constant amber instead of a a flame?

Why can't I actually just light a cigarette on fire (like I could light a stick on fire and cause a dancing flame)? 


Second cigarette related question....why do wet cigarettes smell stronger/worse? I just smoked a cigarette in the rain and it got a few drops on it. Now I'm noticeably smellier than usual.

It has to do with the design of the paper in the cigarette. There is a surprisig amount of engineering wit cigarettes. The paper contains a chemical called titanium oxide which controls and sustains the burning of the paper. Also on the paper are 'burn rings'. These rings are spaced along the paper to slow the burn rate between tokes. 

Wet cigarette smell might have to do with the ammonia in the cigarette which is there to control the delivery of the 2 mg of nicotine.
