wrong in that part , because all the vices you mentioned are completely to spend money but in gambling there is a chance to gain more though it is smaller percent yet there is far different than those others so addiction in gambling is harder to achieve .
and also you are correct that those are all leading to same thing and that is to lose our life if not managed correctly .
Actually what I know is that
]stopping gambling addiction is easier to do than quitting addiction from drugs,agreed mate , though that is not what the topic stands but yes I have some colleagues that got to quit in gambling but never in drugs.
though I believe that most drug addict are also gamblers(if they have a chance of having enough money to gamble)
But depending on each human being, there are those who can heal themselves, there are also those who are desperate for it because they are frustrated because they have lost everything and have lots of debt everywhere, making it difficult to get up to recover. Logically, it will not make him die if he has to leave gambling, which is actually not must be done, simply reducing gambling is more than enough.
of course it is always depend in that person because we have all different on going and decisioning in life , but what we are talking here is the majority generally .
