The New York Publishing firm of Har Der and Rowe will oublish a book on the heroin and opium traff icking in Southeast Asia- over the strong objections of the CIA. THE POLITICS OF HEROIN IN SOUTHEAST ASIA was written bv researcher Alfred McCoy. The ClA's General Counsel Lawrence Houston contacted Harper and Kowe last month to obtain a copy of the work. And then, on July 28th, Houston wrote to the publishers, urging them not to publish the book, which implicates CIA operatives in opium-smuggling activities. Houston nsisted that publi catión of McCoy's work would (quote) "Do a vice in the fight against narcotics traff icking in southeast Asia." i Author McCoy has charged that CIA agents have "harassed" both the publishers and him personally with a series of visits, phone calis and letters. The author said his book documents the movement of opium from the Golden Triangle in Southeast Asia with the use of CIA equipment and men. He said the agency admitted in its criticism of the book that one of its mercenary army commanders, Laotian General Chao La, had maintained a heroin laboratory in Northwest Thailand between 1966 and 1971 -with a full knowledge of CIA officials.
