Yes, you can smoke at Tehran Mehrabad International Airport (THR) — open-air smoking outside the terminal buildings, landside, is permitted; the airport publishes no designated area. No smoking facility inside the terminal or after security is confirmed.
Mehrabad sits a few kilometres west of central Tehran and has handled only domestic flights since 2008, split across several terminal buildings — Terminal 1 (a preserved historic building), Terminal 2 (the main scheduled-service terminal), and Terminal 4, with Terminal 6 as its arrivals hall.
Terminal Buildings
No smoking facility inside any of Mehrabad’s terminals, or past security at any of them, is confirmed. Travel-guide sites describe a smoking area past security in the Terminal 4/6 departure waiting room, near the corner closest to the runway, and another in Terminal 2’s waiting area; a separate listing describes a smoking room inside the CIP lounge in Terminal 1, which needs an exclusive booking rather than a standard lounge pass. None of these accounts is dated or independently confirmed, so plan to smoke in the open air outside your terminal’s entrance before check-in or security — once you are through the checkpoint there is no way back out to smoke without re-screening.
Outdoor Smoking
Landside, open-air smoking outside whichever terminal building you are departing from or arriving at is permitted; this is the only confirmed smoking option at Mehrabad.
Vaping
The airport publishes no separate rule for e-cigarettes at Mehrabad — use the same open-air landside option as for cigarettes.
