Also, many countries have official gambling age but their citizens also violate this age standard.
All these abnormal ways of gambling promote gambling abuse and possible addiction which further makes gambling a societal menace.
Gambling abuses are the ones that result in gambling addiction, so I think you are still talking about the same thing because when we say someone is abusing something, that means they are using it in an abnormal manner. For example, when someone is gambling anytime or taking gambling as a source of income, these are people who abuse gambling, and definitely they will result in gambling addiction. So think about it: when you say someone is abusing gambling, that is what will result in gambling addiction.
Instead of outrightly banning gambling, how about if the concerned countries officially include gambling education in their academic syllabus, just like sex education is taught in schools. Gambling education will teach the young ones the dangers of gambling and promote moderation in gambling. Will this not be a better way to handle the gambling cases?
If a country bans gambling, they automatically ban it, especially if they didn’t just ban it, but their religion is against gambling, so you can see that they won’t even think of introducing gambling education in that country, especially if it's full of Islamic religion or any other religion that goes against gambling, just like Saudi Arabia. Now, I believe there are gamblers there, but I don’t know if they ban it, but we all know they are almost Muslims. Are we going to say these people should include gambling education in their syllabus? Nah mate. If a country bans gambling, they automatically ban it, and nothing they will do, and any citizens who gamble and find out will be punished because they go against the country's law.
