Here's the straight answer - no printed expiration dates exist on cigarette packs. The WHO actually banned this practice to prevent smokers thinking any smoking could be "safe" within a certain period. But that doesn't mean your old pack behind the couch is still good.
When Cigarettes Go Bad
From personal experience, an opened pack starts losing quality within days. The changes I've noticed:
- 2-3 days exposed: Menthol flavors fade noticeably
- 1 week: Tobacco becomes drier, harsher on the throat
- 1 month+: That distinct stale smell develops - like old hay
Spotting Stale Cigarettes
Before lighting up, check these signs:
- Feel test: Fresh cigarettes roll smoothly between fingers without crumbling
- Smell test: Should have a sweet, raisin-like aroma - not papery
- Visual check: Yellowed filters or faded packaging colors indicate age
Storage Matters
Found these methods work best through trial and error:
- Best: Unopened in original foil, stored in cool dark place (not fridge)
- Okay: Ziplock bag with air squeezed out
- Worst: Car glovebox or pants pocket - heat and moisture ruin them fast
