Gambling and sports betting: when play becomes addiction

Updated Six Habits Editorial Team
The short answerGambling is a health risk, not just a financial one. The Lancet Public Health Commission estimated that hundreds of millions of adults worldwide gamble riskily and about 80 million have problem gambling or gambling disorder. Online casinos and sports betting apps, now legal in most U.S. states, carry especially high risk because they are available 24/7 and fast.

Key points

The scale of the problem

The Lancet Public Health Commission on gambling estimated that about 80 million adults worldwide have problem gambling or gambling disorder, and hundreds of millions more experience some harm. The Commission called for treating gambling as a public health issue (Wardle et al., 2024).

Since the U.S. Supreme Court struck down the federal ban on sports betting in 2018, most states have legalized it, and calls to problem gambling helplines have risen.

Why online gambling is especially risky

Problem gambling is strongly linked to depression and suicidal behavior; suicide prevention strategies include reducing access to means of harm and supporting people in crisis (Zalsman et al., 2016).

What to do

Mobile betting allows fast, frequent bets at any time, including in-game bets, which researchers link to higher risk.
