Many respectable people put gambling, alcoholism and drug addiction on the same level because all of these activities negatively affect the human psyche in the acute phase. If you drink a glass of wine on Fridays or play poker, it does not mean that it will negatively affect your health. But you should always remember that any hobby that can grow into a habit must be controlled.
It's pretty much the same thing. That's how addiction is formed, you do something, get the dopamine effect, you feel good at the moment, and then in the long term you have negative consequences.
It doesn't matter if the thing is tobacco, alcohol, chocolate, or gambling. You feel good in the moment, and you continue doing it because of it.

The people with long term mindset tend to be healthier and wealthier than the ones with short term mindset.
