Looking for a Denver Airport smoking area? Denver International (DEN) is a non-smoking facility there is no smoking or vaping anywhere inside the airport, and nothing at all past security. What DEN does unusually well is publish the exact doors where its designated outdoor areas are, so you don't have to guess. This guide lists every one of them, explains the real time cost of stepping out from a concourse, and covers the rules for vaping, IQOS, and cannabis.
📋 Denver Airport Smoking Policy
DEN is a non-smoking facility. Smoking and vaping are prohibited everywhere inside the airport the Jeppesen Terminal, all three concourses, boarding gates, restaurants, bars, airline lounges, restrooms, and the train platforms. Clearing security does not open up any options.
The designated smoking areas are all outside the Jeppesen Terminal and pre-security. Cigarette disposal receptacles are provided at these locations. If you leave the gate area to smoke, you have to come back through a security checkpoint.
💡 Good to Know
Most airports tell you smoking areas exist “outside the terminal” and leave you to find them. DEN publishes the specific door numbers on each level, which means you can plan your break before you even land. The full list is in the next section.
📍 Where Are the Smoking Areas at Denver Airport?
All of them are outdoors, on the public side of security, immediately outside the Jeppesen Terminal. There is nothing in the concourses and nothing beyond the checkpoints.
Outside the Terminal
Pre-security onlyMarked areas sit just outside specific doors on Levels 4, 5, and 6 of the Jeppesen Terminal, on both the west and east sides, plus locations near the DEN Plaza. Disposal receptacles are provided.
✔ Best for: Smoking before check-in, or right after you land.
✔ Access: Jeppesen Terminal only, on the public side of security.
Past Security
Not availableSmoking areas are not available past security. Concourses A, B, and C have no smoking rooms, terraces, or ventilated cabins, and the airline lounges are smoke-free as indoor spaces.
✔ Your options: Return to the terminal and be re-screened, or wait.
✔ Note: This applies to vapes and heated tobacco too.
⭐ The Short Answer
No, you cannot smoke after security at Denver Airport. Use one of the designated areas outside the Jeppesen Terminal before you go through screening and if you're already at a concourse, factor in the train ride each way.
🗺️ Every Designated Smoking Area at DEN
DEN's designated areas are grouped by which side of the Jeppesen Terminal they're on and which level you're standing on. Find the door number nearest to you and step outside the marked area is right there.
Jeppesen Terminal Smoking Doors
| Level | West Side | East Side |
|---|---|---|
| Level 4 | Doors 400 and 416 | Doors 401 and 417 |
| Level 5 | Doors 500 and 516 | Door 517 |
| Level 6 | Door 616 | Doors 601 and 617 |
DEN Plaza Area
Outside the south center doors of the terminal, then to the far right or far left before you reach the plaza entrance. Cigarette disposal receptacles are provided in these areas as well.
🔢 The Door Numbering Trick
Two patterns make this easy to remember without checking a map. The first digit is the level — a 5xx door is on Level 5. And even numbers are on the west side, odd numbers on the east. So if you're on Level 6 and see Door 617, you already know you're on the east side of the terminal.
🚆 The Train Problem: Why DEN Costs More Than Most Airports
Here's the part that catches connecting passengers out, and it's the single most important thing to understand about smoking at DEN. All the smoking areas are at the Jeppesen Terminal. But almost nobody flies from the Jeppesen Terminal — the gates are in Concourses A, B, and C, which sit out on the airfield and are reached by an underground train.
So if you're sitting at a gate in Concourse B or C and want a cigarette, the round trip is: train back to the terminal, exit security, walk to a designated door, smoke, walk back, queue at a checkpoint, then train out to your concourse again. That is a fundamentally longer errand than stepping onto a curb.
Concourse A
The closest to the terminal, and the only one also reachable on foot via the pedestrian bridge. Still airside, so no smoking on the bridge either.
Concourse B
Train only. Add the ride in both directions to any smoke break you're considering.
Concourse C
The farthest out. Realistically the worst place at DEN to decide you need a cigarette.
⏳ Do the Math First
Train ride, walk to the door, the cigarette itself, walk back, security queue, train ride again. Even when everything runs smoothly this is a substantial round trip, and the security queue is the part you cannot predict. From Concourse C on a busy morning, plan on it eating a large chunk of your layover.
🔁 Leaving the Secure Area and Coming Back
You can leave and return with a valid boarding pass, and your checked bags stay with the airline. The variables are the checkpoint queue and, if you're coming from a concourse, the train.
✅ Makes Sense If
- ✔ You haven't gone through security yet
- ✔ You've just landed and are collecting bags
- ✔ You have three hours or more before boarding
- ✔ You have TSA PreCheck or CLEAR
- ✔ Your gate is in Concourse A
❌ Think Twice If
- You're in Concourse B or C on a short connection
- Boarding starts within 90 minutes
- The checkpoint queue is visibly long
- There's a snowstorm or severe weather
- You'd be cutting into your boarding time to do it
🚨 Never Do This
Don't smoke or vape in a restroom, stairwell, or on a train platform. Smoke detectors are sensitive, a false alarm can disrupt a whole concourse, and smoking in a prohibited area can result in a penalty.
🔄 Can You Smoke During a Layover at Denver Airport?
Only by returning to the Jeppesen Terminal and leaving the secure area. Because DEN is a major connecting hub with concourses out on the airfield, the honest answer for most layovers is that it isn't worth it.
Under 2 Hours
Don't Attempt ItThe train in both directions plus a security screening makes this a genuine risk to your connection, not a minor inconvenience.
Stay airside. Nicotine gum, lozenges, or pouches are permitted at the gate and on board.
2–3 Hours
Possible, With CareWorkable from Concourse A, tighter from B or C. Check the checkpoint wait time before you commit, and confirm your gate hasn't moved.
Use the nearest designated door to the checkpoint you'll return through.
Over 3 Hours
ComfortableEnough time to go out to the DEN Plaza area without pressure, and to get a proper meal in the terminal before heading back through.
Set an alarm and allow a full hour to clear security and reach your concourse.
🛂 International Connections
The US has no international transit corridor, so passengers arriving from abroad normally clear immigration and customs at Denver no matter where they're flying next. That puts you on the public side of the airport, so you can smoke outside the terminal before re-checking bags and going back through security.
One exception: if you flew from a US preclearance airport — Dublin, Shannon, Abu Dhabi, or the major Canadian airports — you cleared US immigration before departure and arrive at DEN as a domestic passenger, on the airside. In that case you'll need to take the train back to the terminal and exit like everyone else.
💨 Can You Vape at Denver Airport?
No. DEN's policy states plainly that smoking and vaping are not permitted anywhere inside the airport. E-cigarettes, disposable vapes, and refillable devices are all treated the same as cigarettes, and the designated outdoor areas are the only place to use them.
Being discreet doesn't change the rule. Vaping at a gate, in a restroom, or on a train platform is the same violation as lighting a cigarette there.
Inside the Airport
Vaping is prohibited in the terminal, all concourses, lounges, restaurants, restrooms, and on the train.
Designated Doors
The marked areas outside the Jeppesen Terminal are where vaping is permitted, pre-security.
Carrying Your Vape
E-cigarettes 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.
🔋 Battery Reminder
Spare lithium batteries must be in your carry-on and protected against short circuits. Devices should be switched off and secured so they can't activate accidentally in a bag.
📜 What About Cannabis in Colorado?
This question comes up constantly at DEN, so it's worth answering directly: recreational cannabis being legal in Colorado does not make it permitted at the airport. DEN prohibits it on airport property, and the designated smoking areas are for tobacco products only.
Air travel is also governed by federal law regardless of state rules, so cannabis cannot be taken on a flight departing from or arriving at DEN, in either carry-on or checked baggage. The sensible approach is simply not to bring any to the airport.
⚖️ Don't Risk It
Consuming cannabis at the airport or attempting to fly with it can lead to confiscation and referral to law enforcement, and for non-US travelers it can create immigration consequences well beyond a missed flight. Policies are enforced independently of Colorado state law.
🔥 Can You Use IQOS or Heated Tobacco Products?
Heated tobacco devices such as IQOS and glo warm tobacco instead of burning it, which leads some travelers to expect an exemption. DEN doesn't make one: they fall under the same prohibition, so they can only be used in the designated outdoor areas.
Indoor Use
Using heated tobacco anywhere inside the airport is prohibited, including at the gate.
Availability
Heated tobacco consumables are far less widely sold in the US than in Europe or Asia, so bring your own supply.
Best Practice
Treat the device exactly like a cigarette: outside the terminal, at a designated door.

💡 Tips for Smokers Traveling Through Denver
DEN has its own quirks the concourse layout, the altitude, and Colorado weather that can turn in an afternoon. These are the habits worth adopting.
Smoke Before You Screen
At DEN this matters more than anywhere, because getting back out means the train as well as the checkpoint.
Remember Your Door Number
Note the door you came out of. It's the fastest way back to the right checkpoint in a terminal this large.
Mind the Altitude and Sun
Denver sits over a mile above sea level. The air is dry and the sun is intense even when it's cold, so take water and don't linger unprotected.
Watch the Weather
DEN gets serious snow and wind, and conditions change fast. Keep your coat with you rather than in the overhead bin.
Pack an Alternative
Given the train, nicotine gum or pouches are a more realistic solution at DEN than at most airports.
Check the Queue First
Look up the current security wait before deciding to leave. It's the one unpredictable part of the round trip.
⚠️ Common Mistakes to Avoid
🚨 Avoid These Mistakes
- Assuming a hub this big must have a smoking area in one of the concourses.
- Forgetting the train when working out whether you have time.
- Leaving Concourse C for a cigarette on a two-hour connection.
- Assuming Colorado's cannabis laws apply inside the airport.
- Vaping quietly at the gate and assuming it's tolerated.
- Packing your vape or spare batteries in checked baggage.
⭐ Make Your Layover More Comfortable
If leaving the secure area isn't practical, the next best thing is somewhere comfortable to wait it out. That's exactly what lounge access and meet & greet services are for.
Turn a Long Wait Into a Break
Airport lounge access at DEN gives you a quiet place to sit, eat, and work between flights particularly useful at an airport where a smoke break means two train rides and another trip through security.
Meet & Greet service adds personal assistance through check-in, screening, and the concourses, which helps a great deal in a terminal as large as Jeppesen.
View Denver Airport Services🏁 Before You Fly
Denver International is a non-smoking facility with nothing available past security. All the designated areas are outside the Jeppesen Terminal, pre-security, at specific doors on Levels 4, 5, and 6 — plus the DEN Plaza area outside the south center doors. Remember that even numbers are west and odd numbers are east, and that the first digit is the level. Most importantly, if your gate is in Concourse B or C, factor the train into your thinking before you set off: at DEN a cigarette costs more time than at almost any other US hub.
