The effects of the barbiturates have long been scientifically understood, and our policy on them was simply one of putting into practice existing knowledge. Our use of these drugs was negligible. The effects of the ataractic drugs, unlike those of the barbiturates, are not yet fully understood. Our use of them, therefore, was necessarily more experimental. But we were not attempting to establish large scientific truths about these new drugs, for the therapeutic community project was not a drug research project.
