Most people are aware of the harms of problem gambling. Playing pokie machines, placing bets and visiting casinos can be a very expensive form of entertainment. And when gamblers lose more than they can afford, the consequences can be disastrous for the person playing and their family. But gambling products are only harmful when people consume too much of them. Gambling is like alcohol: occasional use is generally safe. So, just like the two-drink maximum for alcohol, establishing guidelines for “responsible” gambling could reduce the risk of overuse.
