How do you tell expiration on cigarettes?

Cigarettes typically have a "best by" or expiration date printed on the packaging, often located on the bottom or side. This date indicates when the manufacturer recommends using the product for optimal freshness and quality. Additionally, if the cigarettes smell stale or have a dry texture, they may have passed their prime, even if the date hasn't yet expired. It's best to avoid smoking cigarettes that are significantly past their expiration date for health and quality reasons.
