Drugs and alcohol, for sure, I can see it. They are a disproportionate drain on the public health apparatus compared to individuals that live a healthy lifestyle. Use of drugs, alcohol, driving motorcycles, eating too much fatty food, participating in dangerous sports, all have a public health components.
I'm not seeing it for gambling. How is that expensive for anyone but the person doing the gambling?
It's expensive for their families as well.
uhhh, try being the child or family member of a problem gambler. almost as consequential as drugs or alcohol in my experience.
Gambling easily ruins more lives than just the gambler’s. It can be as effective as drugs or alcohol in that regard.
