Most people who try to quit smoking try more than once [source: American Cancer Society]. Loving someone who's tried repeatedly to quit -- and failed -- might make you want to give in and give up, and often it shows. Letting them know, instead, that you believe they can do it, even if it's the third, fifth or seventh time they're trying, might prevent them from giving up. Avoid phrases like "I give up! You're never going to quit!" because they can feed the smoker's self-doubt about whether quitting is even possible or worth the effort. Instead, use words of encouragement like "I'm not giving up on you." Statements like that might linger and influence your loved one's decision to stay the course.
Giving up on methods that aren't working is a good idea, though. With smoking, it may be the "same approach, different day" or even "different day, different approach," because it's hard to know when something just might click and connect with a smoker's desire to quit. Keep trying and showing concern while you figure out what definitely isn't working or what's driving them to smoke more.
