Addictions

When I listen to all the stories about alcoholism and nicotine addiction I wonder how Lisa, who smokes often, can just stop smoking and drinking immediately. As soon as her parents caught her smoking, they told her to stop, and she listened. I think that this is unrealistic because nicotine is supposed to take a lot of willpower to get off of, it is very hard for most adults. Lisa, acts like it doesn't even bother her. She must have an amazing amount of willpower to be able to come off cigarettes for the time that she did.
