Psychologists have yet to discover a psychoactive drug used by people that rats will refuse to self-administer.

Question

Quizplus · Accepted Answer

Rats, like humans, have shown a wide range of responses to different psychoactive drugs in experiments. While they will self-administer many drugs (such as cocaine, heroin, and methamphetamine), there are substances that they do not consistently self-administer, indicating a refusal or lack of interest in certain drugs. This suggests that not all psychoactive substances are universally appealing across species for self-administration.
