Most of the addictions avoidance techniques are effective for those who haven't had hard cases of addiction in the past, e.g a newbie who is just coming into gambling can choose to make use of that system to stay away from addiction, which is the best thing to do at some point because for all the while, I have not seen any workable approach that can bring one out of addiction and helping him stay above such, and that is why, it is better to avoid gambling addictions because it can ruin your life at some point.
Most cases of gambling addictions are traceable to over-involvement and chasing a direction for so long, meanwhile, the best way to stay above that is never to state and always allocate limits to all your gambling activities regardless of what the result and outcome may be at the end.
Let's accept it all that there are addiction treatment techniques one can adopt to tackle the spirit of gambling addiction but how many of these techniques were being truly effective on gamblers, if we are into something and our mind is always there, it becomes a difficult task to see someone being an external force taking away what we love doing except we also wish to give up, same thing also applies to those being addicted, if they never determined on their own to quit addiction then any techniques adopted might be ineffective.
A person with gambling addiction does not initially perceive the threat since there is so much pleasure and interest. And when the gambler realizes that he is addicted he already feels pain instead of joy there is no effective cure for gambling addiction. But with the support of family and friends of addicts they can help their loved ones return to a normal life also the first step to overcoming all addictions is acknowledging the addiction problem. Gamblers deny it early on in addiction but when it becomes a real problem they stop trying to deny it so acknowledging the problem is very important.
