If that is not one good argument to start producing cocaine locally, then I don't know!

Save the fish.

Roaming more widely may not be healthy for the salmon.

Totally. They may wander up bad river, strung out looking for another hit - SNAP! Killed by a bear. My fellow, Salmon, please talk to your roe about the dangers of drugs.

Whether it is or is not, is not a function of the cocaine though, but rather idiosyncrasies of the wider ecologies the salmon are in.

If roaming more widely introduces them to more productive food opportunities (or, lower predation) than their closer ecology, then it would be beneficial for them. If it does not, then it wouldn't be. Neither context is determined in the basic finding that cocaine causes them to roam more widely.

They’re in a better mood though.

Just before becoming suicidal some hours later.

I think another study is in order examining how cocaine affects breeding habits.

What about the rats and turtles in sewers? They might become more agresive!

There is trash 80s "horror" movie waiting to be made.

Someone stole that idea and went back in time: https://en.wikipedia.org/wiki/Teenage_Mutant_Ninja_Turtles

Gotta give them something to improve their perception of their living conditions!
