Always making sure this is brief as possible.
From my observation on addiction, i get to see how addiction is like a chain. Individuals moving from one addiction to another and how several addictions or one addiction can give birth/rise to the gambling addiction. We can all agree as an individual there are several things in life we can be addicted to aside gambling.
Substances like like alcohol or stimulants addiction (drinking), Nicotine dopamine and weed addiction (smoking), to mention a few others can influence a responsible gambler into becoming addicted. There are people in the society who gamble to humanize, smoke or drink, or go out on expensive rides and stuffs.
When it becomes difficult for someone is addicted to gambling to quit. I think its not just about quitting gambling he has to do, if he as any other thing he is addicted to he should first quit on those ones because quitting those ones might make him lose interest automatically in gambling.
This is not how i see addiction working, but let's say you would be right. In that case why wouldn't it work other way around? Like quitting smoking to lose automatically interest in drinking or gambling?
There are valid points for losing one addiction at the time, but you aren't talking about the reasoning here. Main problem with drinking is that it lowers your judgement and that can trigger smoking for example. That's why i needed to quit drinking completely for like half year when i quitted smoking.
But that's just me, and i would argue that people doesn't need to start by quitting only one addiction before something else. They can do it in an order that fits them. II would start with the one that is costing me most money and most time.
And sometimes quitting many addictions at once is the best road. Like for people who want to get fit. They sometimes need to change their habits completely in life, in order to keep their health in the future as well. And that requires quitting many vices at once. Imho addictions start from escapism and boredom, and not all addictions even are bad for us financially or health-wise. Some of them are just making our life more manageable trough escapism.
