10 Things Not to Do if You Want Someone to Stop Smoking for Good
10: Don’t Give Up on Them
Most people who successfully quit smoking have tried multiple times before [source: American Cancer Society]. If someone you care about has struggled to quit, it can be tempting to give up on them. However, showing continued support and faith in their ability to quit is essential. Avoid saying things like, "I give up! You’re never going to quit!" as this will only undermine their confidence. Instead, try statements like, "I believe in you," or "You can do this, even if it takes more than one attempt." Encouragement can be a powerful motivator for someone battling nicotine addiction.

Although you should give up on methods that aren't working, always keep trying new ways to approach the situation. Every smoker is different, and sometimes it just takes time for the right strategy to click.
