The research you mentioned specifies in the abstract a probable cause for failing to replicate the same conditions for the experiment: It is possible that during a colony conversion the supplier inadvertently introduced strain differences making the present rats more resistant to xenobiotic consumption.

In my opinion this tells a lot.

BTW: There are other researchers that replicated similar results on similar experiments too: http://www.ncbi.nlm.nih.gov/pubmed/11072395?dopt=Abstract

So is better to see all the experiments to avoid bias.

Why? What they're suggesting is that the genetic markup of the rats made the difference (that's what strain differences mean), not the environment.

And your other linked experiment isn't at all similar and doesn't have similar results. It's not even about opiate addiction.

Btw, Bruce Alexander is still alive and it wouldn't be that hard for him to find the funding to replicate his experiment, with better controls, if he wanted to.
