Brazilians develop a vaccine against cocaine

Brazilians develop a vaccine against cocaine

Brazilian scientists at the Federal University of Minas Gerais (UFMG) are responsible for an invention that can revolutionize drug initiatives: they have developed a vaccine against cocaine, which is being tested in animals. There is also a promise that the drug will end crack cocaine dependence.

The researchers had as a stimulus the number of cocaine addicts in Brazil. Data estimate that there are 2 million users in the country (about 1.75% of the adult population). According to data from the United Nations Office on Drugs and Crime, an average of 0.4% of adults (approximately 19 million) are users of the drug.

The vaccine has a molecule that encourages production of antibodies against cocaine. This molecule captures the drug before it reaches the brain, modifying its shape and reducing the effects caused by cocaine, such as the euphoria coming from the dopamine and responsible for the sensation of pleasure. Without this characteristic, the will to use cocaine would decrease.

Professor Angelo de Fátima, responsible for the research, reported that in a first moment the vaccine will be used in children and adolescents, in the prevention of cocaine abuse and crack. At the Weill Cornell Medical School in New York, a vaccine for the same purpose was being produced since 1996. It differs from the Brazilian version because it uses cocaine itself in its composition, among other substances and is already being tested in humans.
