Most definitely it can be.
You get a terrific buzz when you win and yo get drawn in. Then you lose and you gamble more to make up your loss.
Many people enjoy a flutter, and then they walk away, having lost only what they were prepared to lose.
Many people enjoy alcohol, but some cant't stop once started, its the same with gambling.
Internet gambling is particularly risky I belive because I don't think you'll have an even chance of winning. Play for fun if you enjoy. Set aside what you can afford to lose, because unless you can walk away you will lose it!
If you think you may be addicted.
Good Luck and kind regards,
