Gambling Harm: How It Affects Players and Their Families

Lotteries, pokies, casino games and sports betting are a normal part of life in countries like New Zealand, Australia and the UK. Most people gamble without serious problems. But for a significant minority, gambling causes harm that reaches far beyond the money lost – and it affects the people around them too.
How Gambling Harm Shows Up
- Money. Debts, missed bills, borrowing from family, payday loans or using savings meant for something else.
- Mental health. Stress, anxiety, low mood and sleep problems. Gambling problems often go hand in hand with depression.
- Relationships. Arguments, broken trust and isolation, often because gambling is kept secret.
- Work and study. Lower performance, lost time and, in some cases, losing a job.
- Crime. In the most serious cases, people commit offences to fund gambling or cover losses.
Research suggests each person with a gambling problem affects between five and ten others, from partners and children to friends and colleagues.
Risk Factors
Gambling harm can happen to anyone, but the risk is higher when:
- a person already lives with mental health problems;
- they use several gambling products, or bet on sport frequently;
- they spend large amounts, or gamble on unregulated offshore sites without safer gambling tools;
- alcohol or drugs are involved;
- they are isolated – for example, international students or people new to the country.
Practical Steps to Stay in Control
- Set a budget you can afford to lose before you start, and never use money for bills or rent.
- Use deposit limits and time-outs. Licensed online casinos must offer them – set them on day one, not after a bad session.
- Do not chase losses. Treat money spent as the cost of entertainment, not as something to win back.
- Take breaks and avoid gambling when you are stressed, upset or drinking.
- Self-exclude if you need a longer break. In the UK, GAMSTOP blocks you from every licensed online casino at once.
- Install blocking software on your phone and computer to make gambling sites harder to reach.
