i think gambling addiction is usually one of two mainly things, knowledge that you have won before, and can gain again
People thin that they can win with gambling and that is why they keep gambling on and on until they win again. It is also not much that you have to do.
The fact that you can play games and win money is enough reason for some people to gamble.
Basically, when we play gambling continuously and be a part of life so one day came when gambler become addicted person, So always take a first step with carefully and i suggest for everyone play gambling but not play it in a routine wise, because that way become dangerous for us and it is a seine of addicting.
but i think that a continue playing of gambling do not make person addicted, a person become addicted because he is always in struggle to make more and more money and in this he invest more and more which make him addicted, if you play gambling in a regular routine and investing a limited amount then you do not become addicted.
