The Australian example is only an example of the wise behavior of state agencies regarding control of one of the most sensitive sectors in the economic fabric. In addition to the large percentages that the state deducts from the profits of these companies, the sector also provides important operational capacity and creates jobs. The real stake for the state remains in its ability to balance the profits made by the sector and the repercussions it causes. The gambling industry does not cost the state as much as the cigarette or liquor industry because it is forced to provide health support institutions for those affected by them, while for gambling addicts their health care does not require a large cost since they are affected psychologically and not physically.
You forget that smoking causes both physical and mental problems. Trying to differentiate physical and mental problem isn't possible because they both work cheek by jowl in running the body system. The brain helps the functionalities of the body and vice versa. An injured person can't think straight forward due to pains. Same for a mentally disabled person. He can hurt his body and also feel disheartened. None is good for any human or better than the other problem. What is important, is reducing the high rate of mentally disabled people in the society, especially, those caused by gambling. As the number of gamblers increase a lot in the society. In addition, any form of illness officially mandates lots of money, not minding the type of illness. Saying the government should focus more on physically ill people over mentally ill citizens, isn't completely proper. The only abstract thing in both affected corporeality, is that mentally ill person; addicted gambler can stay unnoticed. Hence, making the process of tracing him difficult by the government. Unlike a physically ill person, that must be noticed immediately by everyone around them. Addiction takes time before society realizes the problem of the gamblers. I don't think anything, should be the reason why one side of the party won't be helped by the government. So, if the government use the money generated via gambling to tackle addicts and then tobacco money for affected smokers.
