Well if you can't control your gambling addiction what you can do instead is find another addiction that is less life threatening like being a smoker or addicted to video games.
how if addiction to video porn. is now im doing this 
I think its not so smart to change one addiction with another. There is so many nice things around us.
Gambling can ruin people's life, pornography can make people emotionally retarded. Every addiction can make chaos in someone's life, so keep it under control.
No, I could say that change other addiction is good too because like gambling and drugs is too risky to be addicted, if you change to something like may be gaming or anything it wont cost you as much as gambling so it will be loss cost of money for sure. This can be one of a kind thing that should change the addiction but do you believe you can change that? Because addicted people can't be distracted with other things easily
i strongly disagree.
if someone has an addictive personality it would make him predisposed to developing all kinds of addictions. so changing it to another addiction is not going to help, it can only get worse.
also i have to add that addiction to anything (like gaming that you mentioned) can be harmful too. and such person should seek professional help IMO.
