Looking for a Las Vegas Airport smoking area? Harry Reid International Airport (LAS), still widely known by its former name McCarran, is the rare US airport where the answer is a resounding yes. You can smoke after security here, in bars and in enclosed gaming lounges where you can play slots while you do it. Vaping is permitted in those same designated areas, which is unusual too. This guide lists every location, explains why Nevada law makes Las Vegas different, and covers the rules for heated tobacco and cannabis.
📋 Las Vegas Airport Smoking Policy
The airport's position is set by state law: in compliance with Nevada law, smoking (including vaping) is prohibited except in the designated areas. So the concourses, gate seating, restaurants, restrooms, shops, and the general terminal are all no-smoking, exactly as you'd expect.
What makes LAS different is what counts as a designated area. At most large US airports the list is “outside on the curb, and nothing else.” Here it includes two named bars and a set of enclosed gaming lounges at the gates, all inside the building.
💡 Good to Know
Compare this with the other big US hubs. Chicago O'Hare, Dallas Fort Worth and Denver have nothing at all past security, so a cigarette means leaving the secure area and queuing for screening again. At Las Vegas you simply walk to a lounge in your concourse.
⚖️ Why Nevada Is Different
This isn't the airport being generous. Nevada's indoor smoking legislation was written with carve-outs for gaming areas and for bars and taverns, reflecting the state's casino economy. Those exemptions are what allow a gaming lounge or a bar to permit smoking indoors while the terminal around it stays smoke-free.
It also explains the shape of the facilities. They aren't plain ventilated booths bolted onto a concourse; they're commercial venues (a bar you can drink in, a lounge you can gamble in) that happen to fall inside a statutory exemption.
🔞 These Are Adults-Only Venues
Because the exemptions apply to gaming and licensed premises, expect the gaming lounges to be restricted to those aged 21 and over. If you're traveling with children you won't be able to take them in, and you shouldn't leave a minor unattended in a concourse. Plan your break around that.
📍 Every Designated Smoking Area at LAS
Here is the complete list of places where smoking and vaping are permitted at Harry Reid International.
All Four Designated Areas
| Area | Location | Type |
|---|---|---|
| Barneys Lounge | C Gates | Bar, at the gates |
| Bud 29 Track Lounge | T1 Esplanade | Bar and lounge |
| Enclosed Gaming Lounges | B, C, D and E Gates | Gaming lounges, at the gates |
| Outdoor areas | Near ticketing and baggage claim | Outdoors, before security |
⭐ The Short Answer
Yes, you can smoke after security at Las Vegas Airport. Head for the enclosed gaming lounge in your concourse, or to Barneys Lounge if you're at the C Gates. No need to leave the secure area or be screened again.
🎲 The Enclosed Gaming Lounges
These are the signature Las Vegas facility and the reason LAS is in a category of its own. Enclosed gaming lounges operate at the B, C, D and E Gates, and they do exactly what the name suggests: a sealed room off the concourse where you can play and smoke at the same time.
For a connecting passenger this is close to ideal. You're airside, indoors, out of the desert heat, and there's a good chance one is within a short walk of your gate. Four of the airport's gate areas are covered, which is far broader coverage than a single smoking room would give.
🍺 Barneys Lounge and Bud 29 Track Lounge
Alongside the gaming lounges, two named bars are designated smoking areas. Both give you somewhere to sit properly rather than stand in a booth.
Barneys Lounge
Located at the C Gates, which puts it airside and within reach if your flight departs from that concourse. A bar rather than a smoking room, so you can have a drink while you're there.
✔ Best for: Passengers departing from the C Gates.
Bud 29 Track Lounge
Located on the T1 Esplanade. Check where the Esplanade sits relative to your position before setting off, particularly if you've already cleared security and are heading to a gate.
✔ Best for: Passengers in the Terminal 1 Esplanade area.
🎯 Check Which Gates You're Using
Read the official list closely and one thing stands out: the gate-area facilities are named for the B, C, D and E Gates. The A Gates don't appear on it.
So the first thing to establish is which letter your gate carries. If it's B, C, D or E you should find a designated area in your concourse. If it isn't, you may need to move, and at LAS moving between gate areas isn't always a simple walk, because the D Gates sit in a separate satellite building reached by tram.
B, C, D or E Gate
A designated area is listed for your concourse. Follow the signage or ask at an information desk.
Any Other Gate
No area is listed for you specifically. Check with staff before assuming you need to travel to another concourse.
The D Gates Tram
The D Gates are a separate satellite building reached by tram, so treat a trip there as a journey rather than a stroll.
💨 Can You Vape at Las Vegas Airport?
Here is where LAS differs from almost every other airport in the world, and it's worth reading the wording carefully. The rule is that smoking, including vaping, is prohibited except in the designated areas. Vaping sits inside the same sentence as smoking, and inside the same exception.
On a plain reading that means the designated areas cover vaping as well as tobacco. That is unusual: airports such as Doha and Hong Kong explicitly carve e-cigarettes out of their smoking facilities, and many US airports ban vaping everywhere indoors with no exception at all.
Not in the Terminal
Vaping is prohibited throughout the concourses, gate seating, restaurants, shops, and restrooms.
Designated Areas
The same exception applies to vaping, so the lounges and outdoor areas are where to use a device.
Carrying Your Vape
Devices and spare batteries must travel in your carry-on baggage, never in checked luggage.
🧴 E-Liquid and Security
E-liquid counts as a liquid at the TSA checkpoint: containers of up to 3.4 oz (100 ml), all fitting inside one quart-sized clear resealable bag. Larger bottles belong in checked baggage, and spare lithium batteries must be protected against short circuits in your carry-on.
🔥 IQOS and Heated Tobacco at LAS
Heated tobacco isn't named separately in the airport's wording, which leaves it in the same bracket as other smoking products: not in the terminal, permitted in the designated areas. Given that the rule explicitly stretches to vaping, a heated tobacco device is very unlikely to be treated more strictly than an e-cigarette.
The practical constraint in the US isn't the rules but the supply. Heated tobacco consumables are far less widely sold in America than in Europe or Asia, so bring your own rather than expecting to find refills at the airport.
📜 Cannabis: Legal in Nevada, Not at the Airport
Nevada permits recreational cannabis, and a great many visitors arrive at LAS assuming that extends to the airport. It doesn't. The designated smoking areas are for tobacco and vaping products, and cannabis is not permitted on airport property.
Air travel is governed by federal law regardless of state rules, so cannabis cannot be carried on a flight in either hand or checked baggage. This catches out departing visitors more than anyone else: you can buy it legally in the city and then find you cannot lawfully take it home.
🚨 Use the Disposal Bins
The airport provides amnesty containers where cannabis can be disposed of before you reach security. If you have any on you, use one rather than trying your luck at the checkpoint. For non-US travelers in particular, a cannabis finding can carry immigration consequences far beyond a missed flight.
🔄 Smoking During a Layover at Las Vegas
LAS is more of a destination airport than a connecting hub, but plenty of passengers do change planes here, and for them this is one of the easiest airports in the country.
Under 90 Minutes
Usually FineWorkable if there's a designated area in the concourse you're already in, since you don't need to leave security.
Use the lounge in your own concourse rather than crossing to another.
90 Min – 3 Hours
ComfortableTime to settle into a gaming lounge or a bar properly, eat, and still reach your gate with no rush at all.
Confirm your departure gate first, then pick the nearest designated area to it.
Over 3 Hours
No ConstraintThe one thing to watch is the clock, because a gaming lounge is an easy place to lose track of time.
Set an alarm on your phone and keep an eye on the departure screens.

💡 Tips for Smokers Traveling Through Las Vegas
LAS is an easy airport for smokers, but a few details are worth knowing before you land.
Know Your Gate Letter
B, C, D and E have designated areas listed. Establish your letter before you go looking for one.
Traveling With Kids?
The gaming lounges are adults-only. With children in tow, the outdoor areas near ticketing are your realistic option.
Avoid the Outdoor Areas in Summer
Las Vegas summers regularly pass 105°F (40°C). The indoor lounges exist, so use them instead of the curb.
Set an Alarm
A gaming lounge with no windows is the easiest place in any airport to lose half an hour without noticing.
Empty Your Pockets First
If you bought cannabis in the city, use the airport's disposal containers before security rather than risking the checkpoint.
Watch for Gate Changes
A gate change can move you to a different concourse, and with it the nearest designated area.
⚠️ Common Mistakes to Avoid
🚨 Avoid These Mistakes
- Leaving the secure area to smoke when a lounge exists in your concourse.
- Assuming Nevada's cannabis laws apply at the airport or on your flight.
- Trying to take children into a gaming lounge.
- Standing outside in July when there's an air-conditioned lounge airside.
- Losing track of boarding time in a windowless gaming room.
- Packing your vape or spare batteries in checked baggage.
🏁 Before You Fly
Las Vegas is the exception among major US airports. Where Chicago, Dallas and Denver offer nothing past security, Harry Reid International has enclosed gaming lounges at the B, C, D and E Gates, plus Barneys Lounge at the C Gates and the Bud 29 Track Lounge on the T1 Esplanade, and vaping is covered by the same exception. Check your gate letter, remember the gaming lounges are 21 and over, and leave the cannabis in the city. Then enjoy what is probably the most relaxed pre-flight cigarette available anywhere in the country.
