David Nutt, professor of neuropsychopharmacology at Imperial College London, told The Sunday Times that bankers' cocaine habits were to blame for the recent financial crisis as well as the 1995 collapse of Barings Bank.
Nutt said the drug made the bankers "overconfident" and prone to taking more risks. He said the cocaine contributed to bankers' "culture of excitement and drive and more and more and more. It is a 'more' drug."
