Yes, Lusaka Kenneth Kaunda International Airport (LUN) has designated smoking areas — though they are outdoor-only. You must use the designated outdoor smoking areas.
Smoking allowed after immigration in the duty free area - look for the sign and find the entrance to the smoking room on the side - the front facing door is locked which may give the impression that the smoking room is closed. Smoking section also available in the SAA lounge if you have access. - (Thanks to an Avid website visitor)
Zambia Smoking Regulations
Zambia’s Tobacco Products Control Act restricts smoking in enclosed public spaces, including airports. Kenneth Kaunda International Airport enforces an indoor smoking ban in general terminal areas, though the post-immigration smoking room provides a designated exception. Penalties exist for smoking in restricted areas, but enforcement varies depending on the location within the airport. Outdoor smoking is generally permitted in areas away from terminal entrances.
