Black smoke is a symptom of an overly rich fuel/air mixture. In other words too much fuel is being mixed with not enough air.
Smoke is usually the result of a combustion process that releases heat. This heat warms the air containing the smoke and as warm air is lighter (less dense) than cold air, the air and smoke rises.
sidestream smoke contains twice as much tar and nicotineas mainstream smoke because sidestream smoke enters the air directly from the burning tobacco.
Cubic Feet per Minute (CFM) is a measure of how much air (or in your case, smoke) can be pushed. So you'r question is irrelevant.
Smoke rises in the air due to the difference in temperature between the smoke and the surrounding air. When materials are burned, the heat causes the air inside the smoke to expand, making it less dense and causing it to rise. This process creates air currents that carry the smoke upwards.
Sidestream smoke is the smoke that escapes from the tip of a cigarette, cigar, or pipe. Sidestream smoke can be as much as half of the smoke from a cigarette.Mainstream smoke is a smoke that is inhaled through a tobacco product and exhaled by a tobacco smoker.
She or he smokes to much or breathes in bad air. Don't smoke that crud ever!
If the pollution in the air is cigarette smoke you can develope lung cancer. Second hand smoke is dangerous.
Smoke is just unburned fuel, too much smoke is not good for the engine. Anything that causes the engine to run rich, or have more fuel in the fuel to air ratio will make it smoke. You can either put in more fuel by using a better lift pump, or using better injectors, or you can starve the engine of air (not recommended) by unhooking the turbo or putting a paper bag over the air filter. Smoke is just wasted power, a truck that burns all this extra fuel runs much faster. Note that the fastest duramax in the world blows little to no smoke.

by convection
Smoke particles move in air due to air currents, also known as convection. The warm air rises, taking the smoke particles along with it. Once the warm air cools down, the smoke particles disperse throughout the surrounding air.
