It leads some to compulsive gambling.

Basketball great Michael Jordan said that he is ashamed of how far he allows gambling to take over his life. He went on to say that he is not a compulsive gambler.

"I've gotten myself into (gambling) situations where I would not walk away and I've pushed the envelope. I want to go out on a limb and win, and sometimes that can take you past the stage where... you know you should probably take a step back from.

"But my drive to win is so great I just step over that line. It's very embarrassing... one of the things you totally regret. So you look at yourself in the mirror and say, 'I was stupid'." (http://www.hindustantimes.com/news/7242_1525844,001800090001.htm)
