Any addiction is notoriously difficult to treat. Most people are able to quit only when they hit rock bottom, but some can't do it even then. Therefore, it is a lot easier to prevent addictions, rather than trying to make people quit. I hope this excellent piece of advice can help people to see the danger and stay away from any addiction, not only smoking, before it is too late. Change is easier to make before it is too late, but your mom was able to change after she hit her rock bottom. Of course she did not do it by herself. The MI approach and your support seemed to make the difference.
