West Yorkshire Police say they have bailed Paul Flowers after charging him with possession of class A and C drugs.
Mr Flowers was arrested by officers from West Yorkshire Police in the Liverpool area last year.
The Methodist minister stepped down as the bank's chairman in June, amid claims of illegal drug use and inappropriate expenses payments.
A West Yorkshire Police spokesman said: "Paul Flowers, 63, of Hollingwood Drive, Bradford, has been charged with two offences of possession of a class A drug and one offence of possession of a class C drug.
"He has been bailed to appear before Leeds magistrates on May 7."
