In a special message transmitted to the Congress on the 11th of January, 1911, in which I concurred in the recommendations made by the Secretary of State in regard to certain needful legislation for the control of our interstate and foreign traffic in opium and other menacing drugs, I quoted from my annual message of December 7, 1909, in which I announced that the results of the International Opium Commission held at Shanghai in February, 1909, at the invitation of the United States, had been laid before this Government; that the report of that commission showed that China was making remarkable progress and admirable efforts toward the eradication of the opium evil; that the interested governments had not permitted their commercial interests to prevent their cooperation in this reform; and, as a result of collateral investigations of the opium question in this country, I recommended that the manufacture, sale, and use of opium in the United States should be more rigorously controlled by legislation. Prior to that time and in continuation of the policy of this Government to secure the cooperation of the interested nations, the United States proposed an international opium conference with full powers for the purpose of clothing with the force of international law the resolutions adopted by the above-mentioned commission, together with their essential corollaries. The other powers concerned cordially responded to the proposal of this Government, and, I am glad to be able to announce, representatives of all the powers assembled in conference at The Hague on the first of this month. Since the passage of the opium-exclusion act, more than twenty States have been animated to modify their pharmacy laws and bring them in accord with the spirit of that act, thus stamping out, to a measure, the intrastate traffic in opium and other habit-forming drugs. But, although I have urged on the Congress the passage of certain measures for Federal control of the interstate and foreign traffic in these drugs, no action has yet been taken. In view of the fact that there is now sitting at The Hague so important a conference, which has under review the municipal laws of the different nations for the mitigation of their opium and other allied evils, a conference which will certainly deal with the international aspects of these evils, it seems to me most essential that the Congress should take immediate action on the anti-narcotic legislation to which I have already called attention by a special message.
