No not really.
Smoke is made up of gas and floating particulate.
There’s absolutely gas in the smoke coming off a fire, Carbon dioxide, carbon monoxide, and your normal mix of nitrogen, left over oxygen, and other things.
But, most of what you can see, the black/gray stuff. Is ash/soot particles that are suspended in the air. These things aren’t gases, they’re solids thatre just light enough that they can float around in the turbulent air for a little bit like dust before eventually falling back down again.
