Addictions is hard to stop that's why one must try to prevent it so that they won't become addicted to anything. However just been saying this before now that addiction doesn't start just in a day, the gambler develops it gradually and that's how it becomes use to him or her. IMO, gambling addiction is the worst of all the things you have mentioned because some people can do anything for them to gamble, they can sell their properties or use people's money to fuel their gambling addiction. But one who's addicted to alcohol and drug might have friends that's also addicted so if this person do not have money to buy the hard drugs/alcohol the next person might have. Although the both are not something one should become addicted to because they are not good.
That's right bro, that's why we have to be able to control ourselves so as not to fall into addiction to something that can harm ourselves, addiction to something is okay as long as it's under our control, as long as we can control it so as not to harm ourselves too much, it's okay in my opinion, don't let us get addicted to things that can harm us so that we can no longer control it.
Excessive addiction in seeking money is also very dangerous in my opinion, because after all when we are addicted and can no longer control it, we can justify all means to be able to fulfill our desires, don't let all other people's rights become our own rights, because we can no longer control it so that our inner eyes are closed to doing indecent things that can harm others, not only ourselves, other people also feel the impact of our carelessness.
