I have not heard of a specifically Swedish addict gene, and I've lived in Sweden for over 6 years. Searching now, I found no mention of that concept, including searching for "missbrukare gen". Surely some may have said it, but it's not a widely held belief that's part of the debate on substance abuse.
And of course this part of the thread started because you made a statement about puritanical Swedish religious beliefs of the 1800s, when it appears that religious beliefs in Sweden during that time were decidedly anti-pietism/anti-puritanical.
What I conclude from all this is that you feel that your generalizations are correct, even though your details are not, and you make statements without worrying about checking those facts, or feeling that you need to explain the reasoning behind your generalizations.
Perfectly fine for you do to that, but it's not the conversation I wanted, or want, to have.
I guess you didn't do much searching if you couldn't find this study[1] from Lund University or this study[2] from Gothenburg University.
From your sophmoric questioning and pedantic ramblings it seems your mind was made up before you even heard the answer.
> Perfectly fine for you do to that, but it's not the conversation I wanted, or want, to have.
Well to be fair I wasn't trying to have a conversation with you, and again, to be fair, you didn't do anything to add something to the general conversation besides your mild nationalism. Classy.

As for the "addict gene", again, this was supposed to be a synonym phrase for a notion of hereditary weakness, I was not implying it has a genetic basis or that genetics was known before Crick. The phrase "addict gene" was quoted because I have heard it in Sweden (in modern times) when discussing these issues.
I'm hardly an expert on Swedish history, just a person who asks questions when I travel. What I know of Swedish history could be written on the back of a postage stamp. I'm afraid I wasted more time on Roman history in school (as you can imagine, Swedish history doesn't come up very often).
