In reply to the discussion: It's not the morphine, it's the size of the cage: Rat Park experiment upturns conventional wisdom [View all]RainDog
(28,784 posts)yes, humans and rats are different, but the original rat studies that showed rats would self-administer morphine until they died, and this was taken to mean ALL rats would do so. So this person changed the conditions of the experiment and the same actions for the rats didn't hold true.
...but that earlier study became the basis for a lot of assumptions about drugs and addiction, even tho, as you note, humans and rats are different.
what they study really contests is whether the first study had the last word to say about the issue in terms of how we frame the debate about drugs and addiction.
and, not only are humans and rats different, individual humans are different.
Addiction exists in some humans but not in others, and some things that are called addictions would be better labeled as habit - habits within particular environments also have different outcomes for different people.
Ranking the addictiveness of various things generally comes from animal studies.
