Ale-Yarok believes that the concept of Harm Reduction should be applied to a number of other fields, in addition to the drug problem. Prostitution and gambling are two such areas. These are vices that will not disappear, no matter how much effort is expended on the attempt to eradicate them. The state should regulate casinos and bordellos in order to control the most harmful aspects of these phenomena, such as the AIDS epidemic, which poses a very real threat to prostitutes and their clientele. Prostitution must be institutionalized, if for no other reason than to enable health authorities to conduct regular check-ups and prevent the spread of disease.
