Smoke is a common hazard. Smoke — including particularly thick fog — can fill areas segmented into 5-foot cubes.

Any area filled with smoke is heavily obscured, blocking vision in or through it.
Any ranged attack made into or through smoke is made with disadvantage.
You cannot breathe in smoke, and must hold your breath.
If smoke overlaps with strong wind, that area of smoke is dispersed. If only part of a smoke cloud overlaps, only that part of the cloud is dispersed.
