Gambling addiction is a very complex issue driven by a combination of psychological predispositions, neurological factors, and environmental influences, with studies finding that it has genetic components as well.
Studies show some people are more impulsive, while others have a higher tendency towards sensation/thrill seeking or difficulty managing emotions. All these and other factors make them more prone to developing "compulsive gambling behaviours".
Also, gambling often causes the brain's reward system to become overly sensitive. This can lead to dopamine-fuelled "highs" that keep the gamble-reward cycle going.
Environmental factors like easy access to gambling opportunities, social influences, and high-stress life events can also increase the risk of developing a gambling addiciton.
Additionally, gambling addiction often co-occurs alongside other mental health conditions like depression, anxiety, or substance abuse, which can make the problem worse.
Addressing gambling addiction typically requires a multi-step, multipronged approach that includes therapy, support groups, and sometimes medication to target its underlying drivers.
As
@Shortie has said, gambling is different in everyone, which is why there are guidelines for treating it but no wide-scale treatments because they have to be personalised and individualised for each person who seeks help depending on their addiction's underlying driving factors.
