$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.
That's the truth and if somebody sees the sign that they're also addicted, they won't admit it and will reject the criticism that has been brought to them. That's the reality from those gamblers that deny their addiction.
As for gambling frequently, it will make you addicted but I also believe that someone who does it frequently and has planned it always on how much he's going to spend and he's aware of that, I think it's hard to judge if he's addicted or not because he still has the control to himself and understands what he's doing.
