From the title of the topic it says solution to gambling or is it supposed to be gambling addiction? gambling itself doesn't require a solution because it's something that's normal and accepted by a lot of people but gambling addiction on the other hand is what needs solution.The best way to stop this crazy addiction is by changing the idea about gambling, your mindset is very important and it's a tool for change
You're right, gambling is not a problem that requires solution it's a game meant to be played for fun and only when players take it too far and get themselves addicted that they need solution for themselves to get rid of the addiction. You are right when the idea and mindset of gambling changes that's when players get addicted. Gambling is supposed to be a game for fun which can earn you some money while playing but some people rely on it so much as a means of earning and by doing so they sometimes put too much money into it and when things don't go well they become desperate to get their money back and that's how It all starts.
Gambling is not a problem that needs solution but when you don't gamble responsibly a solution will be needed for you.
