Meth problem solved?

Virginia police say that meth lab busts have declined 70% between October 2005 - October 2006. They're claiming this decline is due to the decision to remove Sudafed and pseudoephedrine containing products from drugstore shelves. Strange, since pseudoephedrine products weren't removed from the shelves until April 2006. That means a 70% drop in only 6 months. That sounds hard to believe. Somehow I doubt the meth problem will be this easy to solve.
