In the U.S. Senate race between Republican Rand Paul and Democrat Jack Conway, Paul has criticized Attorney General Conway for not stopping the spread of meth, since meth lab busts are up. Conway, however, says meth is easier to make and law enforcement officers are getting better at catching manufacturers, so an increase in meth lab arrests does not necessarily correspond to an increase in meth use. The situation is similar in other states, and Radio Iowa (via) recently reported on the increase in the so-called Shake and Bake technique for making meth.
