Smoke
Smoke obviously can originate from fires, but also from gas-powered vehicles' tailpipe (indicating that the engine made noise), from the occasional artifact and smoker zombies. You can prevent the problems from smoke inhalation by wearing a filter mask or gas mask.

Effects
Eliminates all nearby scents. Dissipates faster in exterior areas. It has 1/2 chance of spreading.
A character in a tile with thick smoke 8 (density 3) and not inside a vehicle will suffer from smoke inhalation with a strength of 4 for 15 turns, and will have its movement points reduced from 10 up to 20 points.
The movement penalty applies to all creatures, but for plant-like ones is more severe. Creatures that don't breathe (such as zombies or robots) aren't affected by all this.
