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