Temptation will be present since you have a gambler friends but there's a way if you really dont want to engage in gambling like avoiding them or making yourself busy in other things.
However if you try to gamble make sure that you can control yourself and you have to set limitation.
Its hard to refrain especially if you're in the mood but you have to do it or else you might become addicted.
In gambling the major problem that most of the gamblers are facing is that they cannot control their emotions. In fact its natural that when we lose money, we always try to convince ourselves to play again and recover the lost, but for most of the time we continue losing money and making the lost more bigger which finally create a big financial problems for us.
I think we need to have limited amount of money to play gambling with and should try our best not to continue playing gambling after reaching that limit.
