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.
Your observation is very clear and acceptable. But base on my experience and observation, I declare that is someone's gambling habit that contribute to gambling addiction. When someone is addicted to gambling, I can assure you that is not all gambling addict that are womaniser, or drug addict. But some some gambling addict are womaniser, they will gamble to the best of their interest and when they win, they will end up lavishing the money on some women forgetting their family. Instead of them to use the money to do something profitable that will be beneficial to them and their families. But in a situation where they loss, they will take their cry to the family, and demanded another money, this will continue gradually until they find themselves in a big mess up or rough situation. And the family will also suffer the consequences.
And for drug addict, when someone is really addicted to hard drugs. It will be very hard/ difficult for him to know himself, take less of having the mentality to gamble, Because their sense of thinking is going to be affected. And the drugs will also kill some parts of their body organs or systems. When someone is addicted to something, it will be very difficult for himself to quit that particular thing. The only advice I have is that, if you don't want to be addicted to something, is better you don't involved yourself in that thing frequently. Because prevention is better and cheaper than cure.
