“ Air pollution has long been a fact of life in Spanish cities, but scientists now say it is not just smog that chokes people as they walk to work or stroll through the park. A new study has found the air in Madrid and Barcelona is also laced with at least five drugs — most prominently cocaine. The Superior Council of Scientific Investigations, a government institute, said on its Web site Thursday that in addition to cocaine, they found trace amounts of amphetamines, opiates, cannabinoids and lysergic acid — a relative of LSD — in two air-quality control stations, one in each city.
