Heroin became illegal in several steps. When it was an over the counter medicine, that was the first step to make it a prescription medicine. Later on, it was taken completely out of the Pharmacia peer. But an intermediate step between that, in 1919, was a court case that rule that doctors could not prescribe heroin to heroin dependent patients. That was a landmark ruling which has really influenced American politics and American treatment of opiate dependant people.
