I read in an article that in Cambodia, as in many other countries whose governments prohibit gambling, there are many illegal casinos for the local population.
That's the thing when you make something illegal, that "something" will find its way to people through the black market... one way or another. Focusing on banning something never works, or it works for a short time, instead of that countries should focus on education, how to deal with vices, and how to have better control over their habits. It's clear that banned and hidden stuff is making people more curious and tempted to try it, it brings a lot of excitement. And in most cases, we are on our own, we learn from what we see around us. And in that "up and down" gambling world that hits us at a young age is dangerous for a young mind without any experience.
