A Vaccine for Heroin? Maybe.

 I recently flew to San Diego to spend a day with Dr. Kim Janda, an organic chemist who has been trying for almost 30 years to develop vaccines against heroin, cocaine, tobacco, methamphetamine, even the date rape drug. It’s a novel use for vaccines that could seriously alter the way people are treated for drug addiction–if only they could make one that works. Dr. Janda is close, but then again, he’s been close for a long time. In todays Science Times, An Addiction Vaccine, Tantalizingly Close.
