Yes, gambling is addictive and that's why it is banned in many countries, but I think that banning it is not right. Adults should have a right to do whatever they want if that not harms anybody physically. I'm not saying that gambling is a good thing but everyone should have the right to make his/her own decisions.
Well your thoughts are not wrong either, but gambling is not really harmful if it is physical but through mentally it is! and I think that is more harmful than physical pain, because physical pain care be cure in just weeks or months but if a person gets addicted in gambling addiction can be cure for about a month or years, but that is if a person become addicted with gambling.
