According to TSA and FAA regulations in 2026, you can bring tobacco products—including cigarettes, cigars, pipe tobacco, and chewing tobacco—in both carry-on and checked luggage. There are no specific TSA prohibitions against these items because they are not considered hazardous materials. However, if you are carrying lighters, the rules become more specific: you can carry one "common" lighter (like a Bic) on your person or in carry-on, but "torch" lighters (blue flame) are strictly prohibited everywhere. For electronic cigarettes and vapes, the rules are the opposite: they must be in your carry-on and are strictly forbidden in checked bags due to the fire risk from lithium batteries. Keep in mind that while the TSA allows these items, you are still subject to the customs laws of your destination country regarding quantity limits and duties.
