Cocaine Vaccine Passes Key Testing Hurdle

Researchers have successfully tested a new vaccine in primates to battle cocaine addiction. Using neuroimaging techniques, they demonstrated the vaccine prevents cocaine from reaching the brain and producing a dopamine induced high. Human trials could begin within the next year.
