The Commit Lozenge and the Nicorette Gum are addictions in themselves, so technically what
you are doing is just trading addictions.
You need to stop the Commit and
you need to educate yourself about the evils of smoking and why you should quit and stay quit.
Go to whyquitdotcom and look through the "Motivation" stories, read the "Education" articles and ask your mom to go outside to smoke.
