Kevin Wolf/ASSOCIATED PRESS Former Vice President Dick Cheney escorts former first lady Nancy Reagan to her seat at a program in her honor on May 11, 2005. She died on Sunday at age 94.

WASHINGTON -- Soon after the news broke that former first lady Nancy Reagan had died on Sunday, obituary writers and old White House staffers set about assessing her legacy. The New York Times credited her with turning around President Ronald Reagan’s sinking poll numbers after the Iran-Contra scandal. Looking for an excuse to run pictures of the first lady talking to the TV character ALF and sitting on Mr. T’s lap, MSNBC tried to make the case that she brought Hollywood to the White House.

All of this sells Nancy Reagan a little short. Her most lasting -- and devastating -- impact may be as a drug war policymaker (although the Reagan record on addressing the AIDS crisis is also shameful).

Not only did her "Just Say No" campaign become as famous as any sitcom star's catchphrase, but she also supported a notorious drug treatment for teenagers that is still being practiced.

Reagan and the first lady were big backers of Straight Inc., a chain of drug rehabilitation centers co-founded by top GOP fundraiser Mel Sembler. The facilities, which treated teenagers, promoted the idea that drug addiction can be conquered through a combination of isolation and verbal and physical abuse.

The treatment, which could go on for months, consisted of daylong sessions in which Straight Inc. staff would yell at or assault residents and then get them to turn on each other. The first lady was so proud of her association with Straight Inc. that she brought Princess Diana to one of the facilities in Springfield, Virginia, for a tour. It didn't matter that "60 Minutes" had published an expose on the chain a year earlier.

Last year, as part of a year-long investigative story on the heroin epidemic and the U.S. drug treatment system, The Huffington Post published an original audio documentary about Straight Inc. and its predecessor, The Seed. Former residents recalled harrowing moments during treatment and described how the experience shaped their lives.

One Straight Inc. resident told us of being forced to humiliate others as part of the program: "I was in this universe where the social currency was the infliction of pain, and I took part in that wholeheartedly so that I could get out of there. And that was my treatment."

He recalled having to verbally punish another resident who later committed suicide.

Mother Jones reported in 2007 that Straight Inc. closed in the '90s after facing several legal judgments. But there have been spinoffs. The treatment philosophy Nancy Reagan promoted persists, especially in teen boot camps and residential treatment centers. Meanwhile, you can still find websites dedicated to helping the survivors of Straight Inc.
