Gambling actually ain't the problem here. Gambling is just a game where people get used to it. The real problem is the attitude of a person who is playing.
It is true. We cannot blame gambling games once we get addicted, there is no problem with those games. The problem is in ourselves, how we play & how we manage time + funds for gambling. The point is on those things, so if we can play normally, means know to limit time & funds during playing the games (
no playing excessively), then everything will be okay. In addition, control your emotions and expectation, realize that don't hope too much to be rich by gambling.
It is easier said than done. I cannot say that we can totally excuse and keep gambling away because addiction does not come to a person out of nowhere. It is the gambling itself that made the person addicted.
As the saying goes, it takes two to tango. We cannot say leave the dope alone, it is the person who should try to control himself, right? You cannot say you can't partly blame that thing which caused the addiction itself in the first place.
