Drug trials on animals, seen from behind a Jain pharmacy counter
I run my family's pharmacy in the old city of Ahmedabad and I grew up Jain. Every few weeks a customer, usually an older Jain auntie, asks me whether a medicine was tested on animals. The honest answer is nearly always yes, somewhere along the line, because regulators have long required it.
Ahimsa, as Mahavira taught it, extends non-harm to every living being, down to insects. So the question is not a trivial one for us. But I also watch people come to the counter in real pain, and I hand them medicines that work because someone, some time, tested them on mice and rabbits. I don't believe the right answer is to refuse them.
Some things I have found useful. The 3Rs principle (Replacement, Reduction, Refinement), proposed by Russell and Burch in 1959, at least gives a direction: replace animal tests where possible, use fewer animals, and cause less suffering to those that are used. And anekāntavāda, the Jain teaching of many-sidedness, reminds me that the auntie, the patient and the researcher each see a real part of the truth.
But I still don't know how to think about complicity. If I sell a medicine developed through harm I did not cause and could not have prevented, am I part of that harm? Is the patient who takes it?
