Whether it is called gambling fever or gambling addiction, they both have a negative effect on the gambler. They results in losses, shattered mental health and what have you. They are negatives and in my estimation, should be treated the same. Do not get addicted to gambling. Do not catch gambling fever either they are not good. Practice good gambling strategies and be a responsible gambler. Remember to take breaks when you feel overwhelmed by a gambling activity.
The only reason we see addiction as something bad is because those who are diagnosed to be suffering from it suffer loses. In the true sense of the word, anything one isn't able to control using is addiction. It will shock most of us to admit that several of us here suffer addiction to this forum. We frequent here and can't resist coming here daily. It's not just because we're in paid campaigns. I've seen members here who aren't in paid campaigns but they're like they sleep and bathe here. Why we don't take that as addiction? It's simple, we believe we aren't in harm's way; so, to say. But if constantly being here deprives us of quality time with family, then it's something to look into too. It harms the family. In a nutshell, I don't believe all addiction is negative.
