you can generally smoke outside all buildings anyway
I am under the impression that the newest smoking laws, effective 1 Feb. 2019, ban smoking within 5 meters outside all public buildings. This includes condos, rental buildings, pubs, hotels, religious buildings, karaoke establishments, restaurants, laundries, salons, cinemas, parking areas, spas, areas for Thai massage, clinics, hospitals, schools, swimming pools, fitness parks, clinics and ‘other places’. The regulations also specify precisely where internal smoking areas in buildings may be located.
I think smoke alarms will be set off, assuming they're functional if one smokes in the loo.
I assume they'll set up smoking areas somewhere, outside, and away from the exits?
In addition to cigarettes and a lighter maybe carry an extra 5,000 baht?
