No. You cannot smoke after security at Porto Airport (OPO / Francisco Sá Carneiro). The terminal is smoke-free, so smoke outdoors before passing through security.
Porto is Portugal’s second-biggest airport and the main gateway to the north of the country, handling carriers such as TAP Air Portugal and Ryanair alongside a wide spread of European low-cost and full-service flights.
Where to Smoke
Smoking at Porto is outdoors only and landside — outside the terminal building, before you pass through security. There is no airside smoking area and no indoor smoking room anywhere in the terminal.
This is the useful detail to remember: Portugal’s 2025 law lets airports keep indoor smoking rooms, and Lisbon (LIS) does operate them — but Porto does not. That makes OPO outdoor-only. To smoke after you have passed the checkpoint, you would have to exit the secure area and re-clear security, so it is far easier to smoke before you go through.
Vaping
Vaping is treated the same as smoking. E-cigarettes are not allowed in the indoor terminal, so use the outdoor area before security if you want to vape.
