Spanish scientists have found traces of cocaine and LSD in the air samples taken in Madrid and Barcelona. Polluted air in the major cities - it has long been known all the facts, but what a surprise it was when a standard set of substances in a polluted air, added drugs.
As a result of studies of air samples were found five drugs, mainly cocaine. According to the government's Institute for Scientific Research, in addition to cocaine in the air found traces of amphetamines, opiates, kanabioidov and lysergic acid, the so-called "relative" of LSD.
Yet scientists insist that there is no reason for concern, since the content of most of these substances in the air is negligible.
