Yes, you can generally purchase cigarettes on Celebrity Cruises, typically through the duty-free shops onboard. These shops offer a variety of tobacco products, including popular cigarette brands, often at tax-free prices. However, it is important to note that any tobacco purchased onboard is usually intended for consumption off the ship or in designated areas. Celebrity maintains a strict non-smoking policy in almost all indoor areas, including staterooms and balconies. If you purchase cigarettes to smoke during your vacation, you must use the clearly marked designated smoking areas, which are typically located on specific outdoor decks. Furthermore, while the shops stock these items, availability can vary depending on the ship's itinerary and local customs regulations. Passengers are also permitted to bring their own cigarettes onboard or purchase them at various ports of call, provided they adhere to the ship's safety and smoking guidelines to avoid significant cleaning fees.
