It's a hobby for most people and an addiction for very few. Or maybe they get addicted to the adrenaline rush. As long as you allocate a budget and don't spend more than you can afford to lose, you should be ok. Some people smoke, some people drink alcohol, some people do drugs. I think poker, even as an addiction is preferable than the rest of the other addictions. Nobody would say chess players have an addiction. All that to say, if you enjoy playing poker, no reason to feel guilty about it.
