Addiction is a Choice?

I am reading Amazon reviews of this book Addiction is a choice. The author Jeff Schaler argues how addiction (of alcohol, nicotine, other substances or behaviours) is a choice and not a disease (as AA and others would like us to believe). I must say that I have mixed feelings about it. I tend to agree with Mr Allen Wiser from Louisville, Kentucky:

On the one hand, i KNOW consciously that i can turn down a drink of scotch or a 40 ounce bottle of beer whenever i want. on the other hand, i can't escape the feeling that i want (note: i won't say "need") these things more than people who do not suffer from an addiction to alcohol. so what am i to conclude?

And the best of all:

we are responsible for the choices that we have made. if we are addicts, the choices may be harder, but they are still ours to make. ... ultimately, the power (to become addiction-free) does not lie with god, or with the collective group of fellow alcoholics. the power lies with you and with me... in the end, we are accountable to god (if he exists) but more importantly to ourselves and to our loved ones.

I salute you, Mr. Wiser, for articulating so well what we always knew in our hearts as the truth.
