Cocaine Vaccine Can Stop Addiction

A british pharmaceutical company, Xenova, has developed a vaccine that could help cocaine addicts break their addiction.

The vaccine, TA-CD, blocks the body from absorbing cocaine into the brain, and therefore does not produce a high. The scientists who developed the vaccine warn that the vaccine will not work for everybody, and some may feel such a strong craving for a high that they move over to other drugs.

Trials with TA-CD have shown promising results, as about half of the treated addicts were able to stay off cocaine for at least six months.
