Scientists develop a vaccine against cocaine

Posted:
WATERLOO (KWWL) -

Researchers in Mexico are hard at work developing a vaccine against cocaine.

The drug is not ready for human trials yet, but it has been tested on rats.

Mexico's National Institute of Psychiatry said the drug has had positive results and managed to block the effects of lethal doses of cocaine.

Tests in rats proved it prevents the passage of the drug into the brain.

Researchers hope the drug will someday be used to fight addiction to cocaine and other drugs.
