There may be as many as 593,000 problem gamblers in Great Britain. The anticipation and thrill of gambling creates a natural high that can become addictive.
The internet has made gambling more accessible, allowing more and more people to do it from home. This is thought to be one of the reasons for the increase in the number of women gamblers.
Problem gamblers are more likely to suffer from low self-esteem, stress , anxiety and depression .
Gambling addicts are also more likely to go to prison as a result of criminal activity. This is almost entirely theft and fraud. And there's also a link between gambling and alcohol abuse. Many gambling addicts are also addicted to alcohol.
But there's evidence that gambling can be successfully treated in the same way as other addictions. Cognitive behavioural therapy usually has the best results.
Specialised addiction services that mainly focus on substance misuse often treat gambling problems, too. They use the same techniques to treat gambling addictions that they use to treat substance misuse.
