I mean no disrespect in this, but most of the respondents so far are only partly correct. It is not smoke, it is just condensing water vapor. This happens for two reasons.

The trapped gas inside a soda bottle is mostly pressurized CO2. Carbon dioxide can "hold" more gasseous water vapor than air can, because of its lower "partial pressure".

so when you release the pressure, you are both cooling the gas, and introducing air, so much of the water vapor is forced to leave the gas and condense as an aerosol of tiny water droplets. This is literally a small "cloud".

This is especially true if the bottle is straight out of the refrigerator, since the cooling effect of releasing the pressure is more dramatic.

It is the release of carbon dioxide (CO2) gas from the bottle after being pressurized into a vacuumed aqueous environment. Carbon dioxide bubbles, known as effervescence or carbonation, occur when the CO2 is dissolved in water or an aqueous solution. This causes the "fizz" in carbonated water and sparkling water, the head to beer, and the cork pop in champagne and sparkling wine. As the gas decompresses, it releases the dissolved carbon dioxide, which is now carbonic acid. This aerial acid causes the "smoke" seen emitting from a container or pressurized carbonated beverage.

The soft drink is under pressure and has carbon dioxide (CO2) gas in it. When you release the cap, the sudden drop in pressure causes some of the gas to bubble out of the mixture and escape into the air. This is why you get that puff of smoke, and also why you see the bubbles form AFTER the pressure is released.

This is the same thing that causes divers to have to depressurize before surfacing from extreme depths. If they rushed to the surface, the pressure on their bodies would drop too quickly and the CO2 gas in their bodies would start to boil and bubble, and this would get into their bloodstream causing "the bends" and possibly death.

That is called effervescense. It's a chemical reaction of carbon dioxide depressurizing from an aqueous solution.

It is called Co2 and it is a chemical component injected into soda to give it that ' fizz' sensation.

CO2 (carbon dioxide) gas.

It's CO2, a gas.

Smoke doesn't.

don't think it is smoke but chemical vapors released
