Scientists in Spain (CSIC) Find Revolutionary New Way of Monitoring Drug Use Through Sewer Water February 7, 2009

Scientists at the Spanish Council for Scientific Research (CSIC) in Barcelona have developed a new method for monitoring the consumption of drugs of abuse in the general population. This method, which was developed using analytical laboratory technology from Applied Biosystems/MDS Analytical Technologies, can measure the levels of substances such as cocaine, amphetamines and cannabis in water from sewage treatment plants to estimate the amounts of various illegal drugs being consumed within specific regions of the country.
The method provides a fully automated, faster and more specific way for estimating drug abuse than has previously been possible, and was published in the May 2008 issue of the scientific journal Analytical Chemistry1.
Traditional methods for estimating drug abuse in the population can be costly and inaccurate, relying on surveys and on social, medical, and criminal statistics. In contrast, this new method uses mass spectrometry, a laboratory technique, to test water from sewage treatment plants and provide accurate, real-time data, extremely quickly and without invading the privacy of members of the public.
The method’s increased speed and efficiency also reduces labor and administrative costs. The use of mass spectrometry-based methods to determine drugs of abuse in sewage and surface waters was developed a few years ago, and this latest development is the first fully automated technique for detecting and measuring multiple compounds simultaneously, offering improved analytical performance and reliability.
This enabled the CSIC scientists in Barcelona to investigate sewage water samples from regions of Barcelona and Valencia for the presence of 19 different compounds simultaneously.
The compounds were from five different classes of drugs: cocaine and related substances, amphetamine-like drugs including ecstasy (MDMA), opiates including heroine and morphine, cannabinoids, and LSD and related products. Eight of these compounds, including heroine and LSD products, had not previously been analyzed in water samples.
