Brazil’s New “DNA” Technology

DNA technology has become a key component in prosecuting the guilty and exonerating the innocent. DNA evidence increases certainty and enhances fairness.

In a new twist, Police Director Leandro Daiello of Brazil said the country has developed technology that works to detect the “DNA” of cocaine. The process involves analyzing trace alkaloids in the cocaine back to coca leaves grown in precise areas of the region.

Cocaine in Bolivia

 In August of 2013, Brazil reported the DNA of the nation’s drugs: approximately 60% of the country’s cocaine came from Bolivia, 30% from Peru, and 10% from Columbia. The process has enabled police to determine the origins of the drug, what other chemicals are being used in the drug’s production, and where the drugs are being transported.

A federal forensic expert for Brazil’s Criminalist Institute, Adriano Maldaner, noted that the drug problem is international, “which makes the exchange of information and training critical.” To date, the technology is being used in a project that has partnered with Bolivia, Paraguay, the United Nations Office on Drugs and Crime, and the United States Drug Enforcement Administration. Laboratories throughout the world are receiving the same samples and comparing their work.

On August 23, 2013, Paraguayan officials seized two tons of cocaine near the country’s border with Brazil. The aforementioned technology and regional cooperation will assist in the investigation.

In nations where access to technology remains limited, adequate policing and access to justice is also inhibited. This scientific advance is another tool in the tool box which may prove to be useful.
