Not wrong but if you're getting too much into it. try to stop
That is right. Gambling is just a way to pass time, by using money. That is no different from other activities such as cycling, climbing and travelling. All those activities cost money and time.
but with gambling, you just tend to "spend" your money a lot faster when things go wrong

You can get addicted to anything, not just gambling, alcohol, or cigarettes. Gambling in itself is not wrong, However, getting addicted to it so badly that it destroys your life is wrong. I have friends who gamble for fun each weekend, and it does them no harm, but they tell me stories of a few gamblers who lost money to pay for electricity bills by gambling it, leaving their entire families without electric.
There is no problem gambling for fun every weekend. As long as family life is not affected, gambling is a good entertainment.
only if you can afford to lose that money. if you have debts or bills to pay, you should never be gambling with that money.
