Yes - there's no danger in smoking on board an airplane, passengers in the early days of commercial aviation were allowed to smoke. The disadvantage being that some air is recirculated, and those non-smoking passengers would be exposed to second-hand smoke. Today that would be totally unacceptable and thus, smoking is prohibited on board aircraft.
You are not allowed to smoke ANYTHING on an airplane.
The smoke is actually ice that freezes in the air
Contrails
It's not smoke, it's steam. When the water in the air passes through the airplane's engines, it warms up and becomes steam.
