What will be the effect of a bad thing? I think gambling is a worst thing and the effects will definitely be worse. In my opinion gambling should be only for fun and not for making money, because if you want to make money from gambling you will lose your own money. You can have party with your friends in casinos but not gambling addiction.
It has been said thousand of times here that gambling should be only for fun and not for making money. Tell this to the operators, casino owners and they should only have fun with their business. Do you think gambling is a worst thing? what can you say about people who are taking drugs. There are other things that are even worst with gambling and you are only looking at the side that is bad but you never looked at the side where gambling can be a good thing.
