Thomas Ritter Re: "No To Needle Exchange" (Editorial, Sept. 1): Even though you concede that numerous scientific studies have concluded that clean needle exchanges prevent the spread of AIDS and do not "encourage higher levels of illegal drug use," you continue to oppose the very programs, such as needle exchange, that are most successful in encouraging drug users to enter treatment. It's ironic that you are willing to sacrifice the lives of the current 20,000 intravenous drug users in San Diego County so as not to be perceived as undermining our government's "successful" campaign against drug abuse. Contrary to your fear-mongering, not a single person has become an intravenous drug user because of the existence of a clean needle exchange program. In fact, thousands have been helped by these programs to get into treatment. And, thanks to these programs, they are not infected with HIV or hepatitis and they don't have to look to the government to pay for the associated medical costs of treating these deadly diseases. The definition of insanity is repeating the same thing over and over and expecting a different result. Tragically, our county Board of Supervisors seems destined to watch another 1,000 lives being lost to AIDS while more than 20 other cities throughout this state, including Los Angeles and San Francisco, take proactive action in implementing life-saving needle exchange programs.
