Can I still get good muscle tone and abs while I smoke?

OK well I'm gonna slowly kick the habit of smoking but it will take time. I am wondering if it would be possible to smoke and still gain good muscles and abs. I know I need to go to the gym workout and eat healthy. I am just wondering if smoking affects it. also does alcohol affect muscle gain if it is hard liquor?
