When a gambling person becomes completely addicted, it is very difficult to bring him back from that position. If you have a friend who is addicted to gambling and can't get back to a normal life, then you can advise him how to live a normal life and make him aware of gambling?
If a family has a gambler then that family must face a lot of problems but if you have a friend in such a situation how do you bring him back and make his family smile?
Gambling is very addictive, most especially, when the person has made some big chunk of money from it, and then starts facing losses on a long run, they still believe that, as they continue playing, they'll hit again.
To help a gambling addict who is a friend, I'll say to him, in every gamble he plays, he'll give me same amount of money he use in playing, be it he wins or not. By the end of the month, I'll show him the total money used on gambling, and then seat him down and do some mathematical calculations, showing him why he needs to stop or reduce his gambling activities.
Yet, using the money to buy something without him having to take from it.This method will mostly work on those who doesn't get much big wins, but little wins.
