Gambling addiction centers are seeing an alarming increase in calls to their helplines. Callers are becoming younger, often men in their 20s and 30s.

Experts believe this has led to an increase in problem gambling. In 2018, the Supreme Court struck down a law banning sports betting. To date, 38 states and Washington, D.C., have legalized the practice, according to the American Gaming Association, which advocates for the industry. The companies behind these apps say they are taking steps to reduce the risk.
