The Royal Society for the Protection of Birds' (RSPB) Centre for Conservation Science, the Bombay Natural History Society (BNHS), Bird Conservation Nepal, IUCN Bangladesh and the University of Cambridge, have made an important finding about a drug that is harmful to vultures. It has come to light that more than a decade after being banned, a drug toxic to vultures is still being prescribed in pharmacies across India. This was found in an undercover investigation led by a group of environmental organisations and universities.

In 2003, the widespread veterinary use of a non-steroidal anti-inflammatory drug (NSAID) diclofenac in cattle was discovered to be decimating the Asian Vulture after entering its food chain.
