(Newser) – Scientists in Mexico are making progress on a front sure to displease the cartels: a heroin vaccine. It seems to have worked in mice, and now researchers are preparing tests on humans, reports the Guardian. The idea behind the vaccine is to make the body immune to the effects of heroin's pleasures, and mice injected with it stopped consuming the drug of their own accord.

"It would be a vaccine for people who are serious addicts, who have not had success with other treatments and decide to use this application to get away from drugs," explains the director of Mexico's National Institute of Psychiatry.
