Cocaine and LSD found in air of Spanish cities – Telegraph

Air pollution has long been a fact of life in Spanish cities, but scientists now say that 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 website that in addition to cocaine, it found trace amounts of amphetamines, opiates, cannabinoids and lysergic acid -a relative of LSD – in air-quality control stations in the cities.
