A study was conducted by the University of Waterloo recently, and it had to do with teenage gambling. Over 10,000 teenagers in Ontario, Newfoundland and Labrador, and Saskatchewan showed that there was a sizable increase in gambling by teens, and they have done so in a number of ways.
Of course, there has been a big surge in online gambling, which makes sense due to the amount of tie that people spend online now. But then were also situations of teenagers buying scratch tickets, or even betting on games with their friends, like darts. Then there was poker and blackjack, or any other general card games. The study puts forth solutions to the parents that are worried that their teenager has a gambling problem, like getting more involved in their child's life and talking to them about what could happen because there is a lot of reason to believe that this is just the start of a lifelong addiction.
It also helps if the parents don't gamble themselves, as children learn a lot from seeing what their parents do. Try playing some games that don't involve gambling (although you can gamble on anything, really). It is tough because gambling has been happening since the beginning of time, and now, there are simply more avenues to do so. Parents can even go so far as to make sure their computers and laptops are in an area where everyone can use it, so everyone can see what they're doing.
