Indeed, addiction is very severe, it really affects the life of each user so much, and it will affect others too, gambling is not really bad, it is depends on the gambler on how we interact and how we dealt with every winning and losing of our game, we need to put all in moderation and make all things be in our control, most espcially ourselves in which we need to take care , our emotions can affect our gameplay.
It always depends on the gambler if how they treat the gambling casinos there are some people are addicted to gambling but why they still stand like a normal player. If you can control your addiction it won't become worst.
Then they are probably not addicted to it. They just love gambling because of whatever reasons they've got. They are just there because they can afford to or are having fun or probably have a lot of time to kill.
An addict gambler is not anymore a normal player. You cannot control your addiction. Addiction in the first place is already a disease which renders the victim unable to control his urges. The vice or whatever it is that the victim is addicted to is the one controlling the brain and the body of the victim.
