No, a thick haze of smoke and chemicals is smog.
Materials like rubber, plastic, and oil produce thick black smoke when burned due to the incomplete combustion of carbon-based compounds. The presence of soot and other particulates in the smoke can make it appear dark and dense.
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.
