Well, let me first say I appreciate your time to make your opinion known, after all, we are all contributing here. But at times, if it's getting to this point of ours, I think it's wise for either of us to go external to research this to ascertain the truth. You know, at times, if we limit it to our understanding alone, we might never move forward in understanding. When I first saw your reply, truly, I was shocked because you are the only one who refuted what I wrote, others agreed to it. And this can only be for a reason, you might not actually know that it is pointing to, even if it is confusing, and whether you like it or not, if a thing is right, nothing can change that fact. When I was replying to you, I never checked for any external articles until our posts had gone back and forth replies. Thereafter, I resorted to external knowledge, and fortunately, I was sided in this argument. It's not about who is wrong or right now but eventually establishing a fact. However, the truth as the case may be, I believe the links below should shed more light on this. Maybe you don't know the meaning of addiction itself. it's the feelings for anything you like to do often and when missed you don't feel good about it. If you can agree that gambling is addictive even people, at the same time some people will always run to it for either fun or money, and this same gambling can make this person lose (negative aspect). It also makes some people win consistently (positive). How do you now entirely say all addictions are bad (negative)? Is this not plain enough? You might want to make your research far or near, it will not change the fact that there are also positive addictions, and all addictions cannot be negative, it's only the negative part that people often focus on and abuse due to its harmful side. But for positive addiction, since it doesn't affect negatively, people often forget about it while some don't even give it a thought at all.
Frankly, I don't know why you relate this to drugs whatsoever, it further shows you do not understand what we are saying here. Drugs can never be positive to anyone, for what temporary gains which will subside over time and will continue to take hold of the victim and ruin the system and brain of the person unless the supervised ones and the ones they use in medicine? Common! Is gambling like that without any positive stories? Can't gambling earn you money? We are talking about gambling and positive addiction, you had better leave drugs out of it, and all those dangerous things that negate positivity which is the context here.

Positive addiction]Conclusively, you can relate the below links and the images thereof to whether or not there is a positive addiction. You can naturally relate them to gambling since they are not gambling articles. I must even say that it surprised me that someone would emphasise that there is no positive addiction. If the context is not mentioned often in gambling, that doesn't mean it doesn't exist. Anything you love doing very much, it could be a hobby anything whatsoever you can be addicted to them, and this doesn't necessarily mean that it will be that they will be hard on you. The same goes for gambling as well, earning regularly doesn't mean you are not addicted to it, and it's not all addictions that are negative/harmful.
TL;dr I'd have to ask you one question, did you read the book by William Glassers titled Positive Addiction or did you only search on Google and send a screenshot of the highlights? did you read the same article you sent me the link to in the first place? could you at least read the introduction section of the second link you sent in your response, you'd understand that sometimes when you see a highlight it doesn't justify the article. In the research, the psychotherapists tried to define positive addiction, which in my terms is a positive habit, as any activity that helps in healing a person who is addicted to gambling, drugs, sex, etc. And whatever activity that affects or makes the brain high can be an addiction, even though it's not a substance. I'm glad at some point in your response, the few parts I read, that you said the link is not related to gambling. How would you link prayer addiction to justifying a positive gambling addiction? And tried to devaluate my valid point of using drug addiction as an example.
I'm not saying you're wrong, neither is the writer of the links you sent. But, I have to tell you that none of the above is correct, it's just personal perspectives from society. In your best interest, not every research you see on Google's first page would you consider right and use in an argument, those are their perspectives and nobody is accurate in literature, including myself. If you don't agree with my perspective I understand pretty well and would take it as your response, it may be valid to you and many other people, but can never be accepted by a lot of reasonable people that some gambling addiction is positive. It's all negative, set aside some time and read the same backup you used in the response and you'll understand better. And if you've not read William Glasser's book titled Positive Addiction, you shouldn't use it in an argument, as you may not have known the context of the work. Don't judge a book by its cover, and I'd add, that you shouldn't judge a book by its title. We only have good habits. Gambling addiction is negative. Using prayer-related terms to justify positive addiction in all other activities of life is worthless. No positive mental disorder, gambling addiction is a mental disorder. Goodluck.
