I accept that surupticious smoking can be a problem. However the staff should be aware of which residents smoke and those who do not.
Furthermore in a well managed home individual assessments will be carried out on all service users.
This can help to identify those residents who are likely to adhere to the no smoking policy or for want of a better phrase "have all their marbles" and are responsible enough to smoke where and when they should do so as opposed to smoke illicitly
The only time I've known illicit smoking to be a problem is in establishments for the mentally impaired.
Whilst the service users in such places should be monitored closely and their ciggies / lighters conphiscated and kept in the office so that they have to ask a member of staff to smoke it has been known sometimes for friends or visiting relatives to pop down the shop and get fresh supplies for them which are smuggled in stashed about their person etc.
Yet with AFD in individual rooms anybody smoking in their rooms will be found out pretty quickly - I did know of one mentally disturbed service user who hid in her wardrobe , lit a ciggie and set the whole contents on fire.!
It was a rare case, in what is a unusual environment and the correct fire precautions meant that the fire did not spread beyond the room of origin.
