In her 2014 series, investigative reporter Karen de Sa discovered that nearly one in four foster children in California was prescribed powerful psychotropic drugs.

Some of these drugs are so strong that they aren't legally approved to use on children. Many of the former foster youths she talked to said they were left in a daze and barely able to comprehend daily life.

The news struck a chord among state lawmakers, and on Tuesday Gov. Jerry Brown signed a set of new laws to regulate and curb the practice.
