Is that always the case? I suspect the hallucinogens that people have selected to intentionally trip on are a bit unusual (intentional dose sizes, presumably they are selected to get the person tripping in some particular timeframe, right? I'm obviously showing some ignorance on this topic).

This would have evolved in our rodent ancestors. They would have nibbled a bit of anything they came across that seemed like it might possibly be food.

Oddly, I gather rats cannot barf, which is why coumarin works as rat killer.

I think your recollection is off by a little. Coumarin is an anticoagulant and damages rats' livers: https://en.wikipedia.org/wiki/Coumarin

You might be thinking of corn gluten meal, which kills rats by preventing them from absorbing water? It's sold as RatX: https://www.ecoclearproducts.com/pages/ratx-faqs
