The real purpose of Buddhist practice is to cut down your addictions and to correct your habitual patterns and this can be achieved as a layperson or as a monk or nun. That brings us to the question of Buddhist ethics—changing habitual patterns and getting rid of the old addictions, such as attachments, and replacing them with love, compassion, generosity, and patience.

"As an alcoholic, who has been sober for 4 years next month, I was troubled by the strength of alcohol. I remember once leaving a one day retreat and feeling so much joy and peace, yet within 10 minutes I pulled over and bought beer. It was such a powerful compulsion. I was powerless, yet amazingly thought I had some measure of control since I could push my binge drinking off to the weekend. I was ignorant of the fact that I was an alcoholic.

Intoxication affected me tremendously on days I did not drink. The belief that we can indulge our intoxication, yet remain unaffected during the rest of the time is false, at least this has been my experience. My mind was very much affected by this poison. It is true with other intoxicants as well, be the intoxication of the body as those listed above, or of the mind like greed, hatred, or simply not living in the present. In fact, intoxication is a way of escaping the present moment.

Ultimately ego, this sense of self that I so need to protect and who so needs to be praised or feel above others, is the most demanding intoxicant."
