Two cocaine drug test ways can identify alcohol with cocaine diluted in it that can help customs officials with their anti-contraband operations, claim Swiss and UK researchers.
Cocaine is amid the most typical drugs of abuse as well as a big number of imaginative ways of smuggling cocaine through the border controls have been declared in past years. One of the last ways involves contrabanding cocaine diluted in liquids that caused the death of one UK person last year after unwittingly drinking from an infected bottle of rum. It is presently inconceivable for customs to verify alcohols for cocaine with no opening the bottle plus causing damage that is difficult in expensive or large alcohol shipments. Besides, a non-incursive approach has the benefit that it won’t arouse the contrabandist’s suspicions and that is why would let investigators track the recipient.
The ways presented in the DTA documents use Raman spectroscopy (RS) that utilizes laser light to recognize molecules, plus magnetic resonance spectroscopy (MRS) that is the way behind clinic MRI scanners. These techniques could identify cocaine levels much lower than the levels usually used in contraband.
The Raman spectroscopy study was performed by the researchers from the Universities of Leeds and Bradford in the UK and utilized portable scanners to check cocaine diluted in ethanol and some branded dark and light rums, in a diversity of colour glass containers; brown, clear, dark green and light green. The cocaine was educible in any liquid tested and through any glass colour.
Dr. Tasnim Munshi, the researcher from the University of Bradford, said that it was difficult to identify cocaine in form of liquid in these environments. However the study demonstrated that utilizing such analytical technique as Raman spectroscopy may successfully identify the presence of the drugs even without removing specimens out of their containers. The researchers believed that a portable Raman instrument would prove vital in the struggle against illegal drug contrabands by means of allowing for the effective and fast screening of various solutions over a short period of time.
The magnetic resonance spectroscopy study was conducted by a Swiss group, led by Dr. Giulio Gambarota from the Swiss Federal Institute of Technology Lausanne. These researchers utilized MRI scanners in order to test wine bottles dissolved by cocaine. MRI scanners are not portable though can test big cargos within several minutes, including evaluation and set up of the outcomes.
Gambarota said that by stimulating collaboration between customs officials or police and local medical departments, this way could be utilized to evaluate great numbers of bottles very fast, giving info not just that there was another substance in the alcohol like with existing scanning techniques, but also what that substance was. He added that this was could be utilized in other types of contrabands where drugs are diluted into liquids, thus there were many further options for use.
