After Dad's death, we moved Mum to more suitable house, that my partner owns, rent free. She has vascular dementia, but has been happy there for three years. Mum smoked in two rooms of previous rented home, magnolia turned caramel and landlord had to have wallpaper and plaster removed from both rooms. We've tried all ways to get her to smoke in the garden, but failed. Mum insists smoking in the conservatory is fine, as 'it's not in the house' but this morning, the whole ground floor was blue with cigarette smoke and its the final straw. I have phoned and ordered a cigarette smoke alarm which we will install on conservatory ceiling. Any cigarette smoke should activate a voice telling her not to smoke inside and to go in the garden. At the moment, the fabrics, wallpaper, clothes, bedlinen, towels, all stink of cigarette smoke. She had a fire in the waste bin last year. So I just hope this alarm works and keeps her out of the building when she smokes. any comment or advice welcome!
