How can I get my dad to TRY to quit smoking?

He always smokes in the house and it’s making me sick. Whenever somebody tells him to go outside, he goes "ugh" and ignores us! The only place in the house that doesn’t smell like smoke is the very BACK room. The worst part is, he smokes at his computer desk and the desk is right around the kitchen! HELP! IS there any free thing to help him quit smoking? Thanks!

How do I stop smoking with no support from friends or family?

I am almost 7 months pregnant, and I have tried many times to stop smoking. I am attempting once more. I get a lot of pressure from my fiancee who also smokes. Also, he seems unwilling to even try to support me through this. My "friends" still light up right in front of me, to the fact where I have to leave the room just to not be around the smoke. Is it even possible to quit with all this going on? Any suggestions?
