Sorry but I disagree with you, illegal or legal casinos are no tool to gamblers becoming addicted to gambling, gambler who are addicted became addicted on their own based or as a result of their own decisions and indecision.
Yes, that's true, the casino won't make someone addicted to gambling but it's ones own actions that either make them addicts or not. Those who gamble a lot often end up as addicts and those who gamble in moderate way doesn't get addicted at all. That's why one should learn about gambling responsibility so he/she won't get addicted to it.
Yes, I agree with your opinion above that the fact of gambling addiction is caused by the mind and hands of irresponsible gamblers and they do not set rules for time limits or money for gambling, the psychological aspect is very serious about the effects of gambling addiction if they do not follow the basic rules for self-protection from gambling addiction will cause mental health problems, economic management is getting worse, emotions cannot be controlled, and many other bad things. Avoid anything that can affect you from gambling addiction and if you feel that you have a mental disorder about gambling then take a break and leave gambling activities, take time for your work and do more activities outside with your friends and family.
