Anti-ecstasy/meth antibodies

Researchers applied for a patent on antibodies that bind to methamphetamine-like compounds such as Ecstasy to quickly remove the drug from a user's bloodstream. Developed by University of Arkansas scientists, the antibodies could eventually be used to prevent some of the drugs' side effects before they occur. From New Scientist:

The team have not yet tested the antibodies in humans, only in rats, but they say that a single injection can reduce the level of drug within the bloodstream for several days. By binding to drug molecules, the antibodies prevent them from reaching tissues like the heart and brain, and mark the compounds for clean up by the body.
