(from the Des Moines Register)
Like many other midwestern states, Iowa recently passed a law restricting sales of the decongestant pseudoepehedrine, which is also a precursor of methamphetamine. The new law has been very effective, with a 75% drop in meth lab seizures since it was passed. However, Walmart has thrown its weight behind efforts to pass a weaker federal law that would also preempt any state regulations.
Iowa Senator Grassley is so angry at the changes that he has withdrawn as a sponsor of the law. The law’s two primary sponsors are Jim Talent (R-MO) and Dianne Feinstein (D-CA).
