The "disease" of alcoholism.

[BluffTHIS!]

The question is whether any very strong addiction, with both physical and psychological components, is a disease. And also at issue is whether to be a disease, something has to be able to be cured medically. However many adverse medical conditions can result from ingestion or exposure to toxins, and decrease or go away entirely when that consumption/exposure is stopped (though there might be permanent damage but which is limited by stopping), although that ususually presumes a will to stop, as in for example habitually eating from a contaminated source (like fish from the East River).
