- Would you blame an individual who becomes addicted to gambling because it is wired to his DNA?
No, even if it his own doings, I still won't blame him. No one likes to be an addict. The person is just a victim of too much dopamine secreted on his brain. Now do we blame the victim?
-Can their gambling problem be put in check by regular methods?
Is there a special means to treat this kind of gambling addict? I can't find any special treatment of this kind on the internet probably they use the same method for gambling disorder withdrawal.
-Will the addiction be worse than someone who picked up the habit?
I don't think so, I believe it is still a matter of decision. If a person is strong will in avoiding gambling activities then I don't see they will be worse than any other gambler.
I'm not sure about the DNA thingy though, maybe it has, but I think it's probably on what they see on their parents that is pass from generations to generations, not DNA per se. If you see you parents at a young age, have gambling sessions in your house (this is prevalent is Asian Culture, playing mah-jong). Definitely you can inherited this as you grow old. So it is still the environment that is the influencing factor and I think majority of gamblers some kind of interaction or exposed to gambling when they are very young. But we have a choice, whether to fall victim or not.
That is what I thought too until I found large numbers of articles and researches regarding this matter.
