Maybe this is semantics, but I find the differentiation between 'disease' and 'genetic predisposition' a slender one, as the predisposition elevates the chance of sucumbing to the disease.
An addictive personality is one that has a problems with certain substances (or behaviours) when they are exposed to it.
Someone can equally have medical problems with other environmental factors when you are exposed to them, due to a genetic predispositon.
In modern society, one can have no knowedge that they will have problems due to exposure to alcohol. People almost always have access to alcohol, most people have no problem with it, most of those that do have a problem with it didn't know that they would when they were first exposed to it. But due to the genetic predispostion they get the disease of alcoholism.
In modern society, one can have no knowedge that they will have problems due to exposure to certain foods. People almost always have access to certain foods, most people have no problem with it, most of those that do have a problem with it didn't know that they would when they were first exposed to it. But due to the genetic predispostion they get heart disease.
What I am saying is that an alcoholic is either totally free of responsibility because it is an unavoidable disease, or they are responsible because they unfortunately have the addiction gene and chose to drink to excess.
If only life did consist of polarised black-and-white choise like that! It would be a lot simpler.
Your argument is an 'excluded middle'.
It also fails to take into account that even when one does include the middle ground, the grey area, that is the fairest represetation of the issue (predisposition is not the same as predestination ), people will have differing degrees of personal responsibility and that to characterise alcoholism as a 'choice' fails to take this into account.
Family history is the best guide, as far as telling if one has that trait. As far as I am aware there is not a specific test as whilst there is a proven genetic predisposition (through hereditry studies), we don't know the exact genes that give this predisposition.
