Thomas Ungerleider MD In your article on San Francisco's propensity to oppose the state and federal governments in health matters, you note its support for needle exchange programs, beginning in 1992, long before they were legally accepted. In 1997, the National Institutes of Health issued a consensus statement on "Interventions to Prevent HIV Risk Behaviors." It stated that needle exchange programs cause powerful beneficial effects, reducing both HIV and drug abuse, and that "there can be no opposition to these programs on scientific grounds." Perhaps our northern neighbors know a lot more than we give them credit for when it comes to protecting their citizens. J. Thomas Ungerleider MD Los Angeles
