Anything can affect a child's educational performance, we should not see gambling nas the only thing that does so, too much playing can contribute to poor performance, lack of balance diet and malnutrition in a child can cause a lot of psychological and emotional imbalance causing poor performance in academic,
While I admit that you're right that gambling isn't the only thing which can affect a child's education, I also want to let you know that apart from drugs, gambling is the next enabler of distraction for children. You know why? It's because it has the lure of money. Money moves everyone, whether we admit it or not. Everyone needs money to solve their problems. Money moves mountains. Children aren't supposed to be exposed to anything money enterprise at their formative age when they are barely able to stand for anything or be able to differentiate their right from their left, so to say. I saw how gambling derailed and destroyed some of my high school mates. I wouldn't, knowing, expose my kids or other children to gambling.
