I believe you are correct that the psychology of drug addiction and gambling addiction differs, despite certain similarities. Drug addiction causes the person to become physiologically reliant on the substance, and when they stop using it, their body may experience withdrawal symptoms. However, in cases of gambling addiction, the individual is typically psychologically addicted on the pleasure and excitement of gambling, and they may not feel physical withdrawal symptoms when they quit. This can make it more challenging to cure gambling addiction because it is harder to persuade someone to give up something they enjoy.
I think Drug addiction is far worse and harder to cure and I can witness that since all of those who get to serve in prison due to their drug addiction whether they were users or pushers, when they get out, they back to where they were left and they ended up becoming worse than before. Unlike most of whom I know that were used to gambling, they have completely changed and don't engage in cock fighting anymore or some Lottos rather they just continue living their lives normally as the others. Drugs lead users to become crazy and there are lots of people who become crazy here in our community right now.
If you really look at both, you'll realize that both gambling addiction and drug addiction can be very devastating in their own way so I wouldn't be wise to compare one to another.
With gambling addiction, a person is likely to loose everything they have, their job, home, family and even their lives. They may also experience financial problems, legal problems and even health problems as a result of their addiction.
And with drug addiction, a person may also lose everything they have,, they're also likely to experience physical health problems as well as legal problems. They may also lose their relationships as well as their mental health.
But one thing we know is that, a gambling addict is likely to take his own life out of frustration and depression but the chances of a drug addict taking his own life is slim.
So it's not really a question of which is worse, but rather a question of how each addiction affects each person's life individually, because they all have different ways they affect others.
