English, tough sentance to structure.?

"Until 1987, the year when the Food and Drug Administration introduced the Prescription Drug Marketing Act, prescription drugs have been distributed without regulation. " I'm using this in a reasearch paper and need to know if it's clear enough, structured correctly. Please help.

The only correction I would make is to change "have" to "had." Until 1987...prescription drugs had been distributed without regulation.

Prescription drugs were distributed without regulation until 1987 when the Food and Drug Administration introduced the Prescription Drug Marketing Act.

It is not necessary to put the words "the year" after 1987.
