fire
Yes, when it is burned (oxidized in air), it releases the chemical energy stored within its chemical bonds.
Coal, gas,oil, and wood. All of these are burned (oxidized in air), which releases the chemical energy stored within its chemical bonds.

there are many cancer causing agents in cigarettes, some we probably haven't found yet. the main carcinogen(cancer causing agent) is acrolein. See the link below for carcinogen compounds in cigarettes smoke.
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
The chemical energy becomes heat energy when the gasoline is burned. Oxidation releases chemical energy stored in the carbon-carbon bonds of fossil fuels and in the diatomic bonds of O2.
Smoke
When coal is burned it releases bad gases into the atmosphere which creates pollution.
Biomass releases carbon dioxide when burned.
carbon monoxide
It is doubtful that it is possible to genetically modify tobacco to make a cancer free cigarette. The problems are that tobacco is cured to give it the flavor, and that the tobacco is burned during smoking. Burning objects tend to produce carcinogens. So it doesn't matter what tobacco is used.However, if you want to make a cancer-free cigarette, you would have to use a technology that doesn't include burning things. So that is where electronic cigarettes come in. They do not burn, so nothing gets turned into carcinogens while you smoke it. That said, the technology is not perfect nor risk free. To make one that tastes like a traditional cigarette, some carcinogens would have to be added. With time, people could get away from wanting that taste. Plus, there is also a risk that ordinary cigarettes don't have, and that is exploding batteries. For some e-cigarettes, the mouthpiece is a modified battery, and if that explodes while you are using it, it could mean dental loss or other injury.
