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.

  • Even in the case it were to benefit the salmon, that could still cause secondary problems: something like how nutrient pollution causes some species to run rampant.
