Nope. From personal experience. I was unable to start a test fire with a lit cigarette. The liquid gas can't catch fire. Its the fumes which are flammable.

In rare circumstances, such as a high wind, the paper on the cigarette can momentarily have a flame on it and its that which ignites the fumes. But it has to be located where the fumes are concentrated such as right above a pool of gas.

Try it yourself. Be safe about it.

The last time I saw someone "test" this he lost his eyebrows and some hair. (Granted, he was drunk and standing right over it... )

Please describe the circumstances and precisely what he did. Thanks.

Hint: Never play with fire when you're drunk.

I do mean to drop the cigarette into a pool of gas. Do not bend over and give a strong drag when the cigarette is 1 cm above the pool of gas. Under such situations the cigarette paper catches fire.

Gasoline and Cigarettes Don’t Mix?

Again, the answer to this should be quite simple, a yes or no answer, but in reality, the answer is slightly more complex. Cigarettes tend to burn at approximately 800-1100 degrees Fahrenheit (source), and can get even hotter during a particularly long drag. Essentially, you are providing more and more oxygen for the fire to burn faster and hotter, thus eating up the tobacco and releasing smoke into your lungs. Now, the ignition temperature of gasoline is much lower than that, roughly 495 degrees Fahrenheit (source).

On paper, this means that the gasoline should ignite quite quickly and an explosion is imminent. However, researchers have proven that this is highly unlikely. When a cigarette is not being “dragged”, the temperature drops considerably, making it harder to ignite.
...
The variables of gasoline vapor, airflow, temperature of the cigarette are all difficult to calculate, but the probability is extremely low that you will go up in flames because you tossed a cigarette butt in a pool of gasoline. One particular study attempted over 2,000 different scenarios and situations where gasoline and a lit cigarette could interact, and not a single attempt resulted in the gasoline catching on fire.

I'll be doing more volunteer work at our local TV station and will eventuall host my own TV plan. I spoke to the people in charge and they loved my ideas. Take note that this is not in the near future but later on this year. This cigarette and gas thing will be something I'll bring up.

He was setting up a bonfire, poured gasoline on it, then lay down flat on the ground and lit it. BOOM!
