The idea that we’re being unwittingly drugged when we drink a glass of ordinary tap water smacks of dystopian science fiction or political conspiracy theory. Accusations that Communists were spiking America’s water with sedatives—under the cover of the federally instituted fluoridation program—were such a staple of Cold War–era paranoia that Stanley Kubrick satirized it in his 1964 masterpiece, Dr. Strangelove. While such fear-mongering may seem quaint, what’s truly ironic is that Americans today are consuming prescription drugs—including addictive psychoactive ones—via the water supply. Who knew? There’s a good chance that if you live in an urban area, your tap water is laced with tiny amounts of antidepressants (mostly SSRIs like Prozac and Effexor), benzodiazepines (like Klonopin, used to reduce symptoms of substance withdrawal) and anticonvulsants (like Topomax, used to treat addiction to alcohol, nicotine, food and even cocaine and crystal meth). Such are the implications of environmental studies that have been leaking out over the past decade.
