If someone you know is trying to quit smoking, there’s a lot you can do to help. Simply being supportive and available to lend an ear is a big part of the process. Propose activities to keep the person active—and away from the temptation to light up.

It’s important to remember that quitting is tough; if your loved one slips up along the way, don’t criticize his or her efforts. When friends seem to be struggling, continue to encourage them and let them know how much you admire them for their efforts. Recognize and congratulate small milestones, and realize that your loved one may be more cranky than usual. Sometimes the best thing you can be is a sounding board, or even an emotional punching bag, for whenever a bad craving strikes. Use the tips below to help make these transitions easier.

Most people try to quit smoking many times before they are successful. Don’t give up your efforts. If the person you care about fails to quit, you can:

* Praise him or her for trying to quit, and for whatever length of time (days, weeks, or months) of not smoking.

* Encourage him or her to try again. Don’t say “If you try again.” Say “When you try again.” Studies show that most people who don’t succeed in quitting will try again in the near future.

* Encourage him or her to learn from the attempt. Things a person learns from a failed attempt to quit may help him or her be successful in a future attempt.

* Suggest that he or she consider more intensive treatment when ready to try again.
