Rat Park, yes. The experiment is widely misreported, and the Wikipedia article doesn't really help. Getting a rat in a rat colony addicted to opiates isn't easy at all, opiates taste so disgustingly bitter that rats just won't touch them. I think they had to go up to 20 % sugar and even then the animals preferred to be thirsty. Some went so far as not to touch the sugar/opiate solution at all and found it better to die of thirst. Contrary to popular opinion/Wikipedia, Rat Park wasn't paradise. The other thing is that opiates don't help rats being rats. Anyone who has ever interacted with rat knows they are curious and social animals, they like to explore, fight and have sex. Nothing you can do while high on opiates. From this angle you'd almost predict that a rat might not like to be addicted to opiates. The experiment actually confirms the hypothesis. Now alcohol on the contrary - it doesn't taste quite as awful, you can have much fun being drunk, have barfights and drunk sex, as Friday night in a British city center confirms, and it works just as well with rats as with humans. The follow-up experiments have been made. No rat ever voluntarily gave up booze.
