The police in my city, Mumbai are taking Hydroxychloroquine. When they researched two sets of groups - those who took the drug as per the prescribed dosage, and those who didn't. The group that wasn't taking the drug had a few deaths, but the other group did not.

Anecdotal and small sample - but definite proof against the idea that "nobody would be talking about it". The drug is also used in Costa Rica and many other parts of the world.

A Jewish doctor in New Jersey - Dr. Vladimir Zelenko wrote to the President about the drug, which is assumed to be the origin of his interest with it. Here is The Daily Beast lambasting him for calling this same lancet study "garbage"
