Meth makers to be foiled by jelly

Specialty drugmaker Highland Pharmaceuticals says it's found a way to halt the production of meth cookers. The St. Louis company has developed a chemical lock of sorts that prevents meth-makers from extracting the "API" pseudoephedrine from common cold and allergy drugs such as Sudafed and Mucinex. The new pseudoephedrine-making process turns the substance into an unusable, jelly-like material when drug-cookers try to extract it. Story
