My mom won’t stop smoking inside the house

I’m supposed to have top surgery on feb. 10th, the surgeon said I have to be 6 weeks clean of any substances. I only smoke the devils lettuce and occasionally drink, I haven’t done anything since before the new year. So I’m fine regarding that. However, my mom smokes inside the house and nicotine is one of the things I have to be clean of too. She said she’d stop smoking inside the house starting jan. 2nd. She has not stopped smoking inside the house. I know its only a few days later, but she has shown no signs of starting to smoke outside. I am also being tested for substances 2 weeks before the surgery date. I asked her earlier when she’d stop smoking inside the house and she replied with “I don’t know” I told her I was getting worried and she didn’t reply. About a minute later she said she was going to bed. She knows how much I’ve been looking forward to this. My dysphoria has been so bad lately that I can’t bring myself to change clothes and I can’t wait any longer than i already have to. I’m not sure what to do or if there’s really any advice to give but anything is welcome

Edit: she went to the consultation with me and knows everything I know. She has been supportive the entire time up until this.

Edit 2: I’ve spoken with my brother and he is going to try to talk to her too.

Edit 3: she has told me she’ll start smoking outside tomorrow, I will hold her up to it. If she doesn’t, I will continue to get onto her about it.
