I like your point here, they have to determine from their heart to change if not everything will results into wasted efforts if care is not taken, there's a stage an addiction will get to and go beyond control except if the person involved willingly determined to change but it would have been too late i most cases because they would have been seriously dealt with and left with no other alternative to live than quitting.
It's not that those addicts don't want to recover from their addiction but it's what's known as "relapse".
After rehabilitation, some if not most
adficts have a tendency to get back to their previous habits (addiction).
Rehabilitation takes time and full recovery from addiction needs a strong will and strong personality from the addict himself. Yet, there will be always a possibility for relapse.
All the same, how hard it is for these people throughout their lives. Even having given up addiction, they, like a tightrope walker over the abyss, go through their life path, at any moment you can fall. After this, you understand how important it is for a person not to start, because the first time is like the first step on this cable car over the abyss for life.
Governments should reduce the aggressive advertising of various gambling houses, so that there are fewer people who will take the first step.
