You can choose to stop smoking. This may prevent future addiction, but will do nothing to stop your immediate withdrawl symptoms. This may prevent future cancer, but will do nothing to stop any current ulcers. Plenty of other illnesses trace back to life choices. Unprotected sex gets you STDs. Not exercising and eating right leads to heart failure. Isolating yourself socially leads to depression. Many of these can also be stopped or reversed after a "moment of clarity" that causes you to change how you live your life. Addiction is not particularly special in this regard.
