Attorneys announced in court Wednesday the tentative settlement of a lawsuit filed by Canadians who suffered emotional trauma from mind-control therapy, including doses of the drug LSD, given them in the 1950s.

Lawyers for the government and the nine original plaintiffs did not specify the amount of the settlement during a brief hearing before U.S. District Judge John Garrett Penn., But sources speaking on condition of anonymity said the CIA had tentatively agreed to pay a lump sum of $750,000 to settle the case.The 1980 lawsuit claimed $1 million for each plaintiff who underwent treatment at a Montreal clinic headed by a psychiatrist whose research into mind-altering techniques was covertly financed by the CIA during the Cold War.
