Cigarettes are consumable items which reduce the stress and hunger of the player character while causing unhappiness. It is planned that characters will become addicted to cigarettes if they take too many.
Cigarettes are relatively common now as they spawn in stacks of twenty at a time, and they may be found in cabinets, crates and desks.
Cigarettes can also be used to make Insect Spray to combat Pest Flies in your garden.
You need a lighter or matches to 'smoke' cigarettes.
