$100 or $200 may not be too much for some people.
However, gambling addiction cannot only be measured by how much you spend every day or every month on gambling, it is also measured on how frequent you gamble.
Usually, a person will never know when he's addicted or not, because we always believe that we gamble normally even If it means that we don't have time for different thing other than our day jobs or business.
I only partially agree with you. It is true that it is dangerous to play too often, but when we have control over it, it's still okay. Problems begin when we play not only in our spare time, but when we neglect our responsibilities just because we want to play. The amount of money is also very important because if we are spending more than planned on gambling, it is a very bad sign.
