How can I tell if I have a gambling addiction?

Cant stop gambling. Gambling addiction like all other addictions has the "cant stop despite the behavior causing problems in the person's social, physical, emotional, financial, or relational life" issue. Gambling addicts tend to develop tolerence, so they will make bigger bets. Some of them have a history of a "big win" which only encourages more risk taking and heavier betting. Gambling trumps all other interests.
