Why an old teratogenic drug cost so much?

THALIDOMIDE is used to treat multiple myeloma

This was banned after it was given to pregnant woman causing their children to be born with no limbs or very shortened limbs a condition called phocomelia.

after a number of years, scientists and doctors found this may work in the treatment of multiple myeloma. and once again  our good old  pharma companies are scrambling to gather the  silver coins  from dead bodies
Charon's obol is an allusive term for the coin placed in or on the mouth^[1] of a dead person before burial. Greek and Latin literary sources specify the coin as an obol, and explain it as a payment or bribe for Charon, the ferryman who conveyed souls across the river that divided the world of the living from the world of the dead. Archaeological examples of these coins, of various denominations in practice, have been called "the most famous grave goods from antiquity."^[2]
