> That is hardly a good explanation to avoid scientific research.
I agree it's not, because it's not about research, but rather about science and "science" reporting as well as what ends up in the "news" ("researchers find the addiction gene"). That's why I said it is important to consider the magnitude before talking about it, not before researching it, because obviously you don't know the impact before the research is done.
One of the eras of extreme racial stereotyping happened when there was very little knowledge about the genetic science.
If there is a genetic component to opioid addiction then it would be extremely helpful to treat it with that knowledge.
