Does High Temperature in a Car Affect Cigarettes?

[AlexaFitz]

Cigarettes left in a car under high temperatures can be affected. Since cigarettes are sensitive to heat, their shelf life is related to how they are stored. Cigarettes are susceptible to environmental and temperature changes. If stored in hot weather, they may deteriorate or become moldy. Below is relevant information: 1. Ignition Point of Cigarettes: Cigarettes require at least 200 degrees Celsius to ignite, and even the cigarette paper needs 100 degrees Celsius. Unless a convex lens or magnifying glass is used to concentrate sunlight, and there is no wind to dissipate heat, the temperature rise would not be fast enough to reach the ignition point. 2. Additional Information: In hot weather, cigarettes are prone to environmental and temperature changes. If stored in a sealed plastic bag for a long time, their flavor may degrade. Cigarettes can be stored in a cool, ventilated, and dry environment for 1-2 years without needing to be unpacked.
