By Dialogo October 29, 2012 A team of 10 forensic chemists from Central America, the Caribbean and Mexico attended an internship on illicit drug analysis this week in forensic labs in Bogota and Cali. The aim is cooperation in the fight against crime that Colombia provides the isthmus. These practices help to train forensic chemists from Mexico, Guatemala, Costa Rica, Dominican Republic, Panama, and El Salvador, to detect drug purity levels and the camouflage used on the substances, as well as how to testify on technical matters in drug trafficking trials. This activity ratifies the “Colombian government’s determination to support Central America in counter drug issues,” said William Garzón, an official at the Colombian Attorney’s Office. In addition, coordination allows better trade detection methods and new drug trafficking techniques, according to expert chemist Franklin Muñoz. “About a year ago, black cocaine became popular in Colombia. It was nothing but common cocaine with a reagent that changed its usual color, so we would think it was something else,” he said. In 2011 they seized 400 hundred tons of drugs in Colombia, of which 145 tons were cocaine, according to the Ministry of Justice.
