I am also a smoker and have this concern. I bring home my G2 on the 30th of this month and I really think I'm going to quit.
We moved houses in April, and before moving we always smoked inside the house unless I was babysitting. After we moved, we (my partner and I both smoke, as does my mother who lives next door to us, we live in her guest house) all decided to smoke outside. After smoking outside now, I visited a friend's home who smokes inside and I couldn't believe the smell. I asked my friend (non smoker, visiting with me) if that's what my house used to smell like. She just gave me this look like "Are you serious?" and said "Um... yeah." With the tone of, "of course it did." After that, I am so glad we smoke outside because it STINKS.
I like smoking, I've smoked for 4 years, but I just don't think it's worth it. I've heard from multiple sources that even if you smoke outside, the nicotine from your hands can get on your bird's feathers and cause plucking. No one wants that, especially in 'toos. My doctor also just told me that if I'm interested, he'd write me a prescription for Chantix. Definitely something to think about.
P.S. Good for you for putting your bird before yourself.
