What Happened To The Methamphetamine Eradication Act of 2005?

I read that the Methamphetamine Eradication Act of 2005 was an action by the United States government aimed to eradicate the production and trafficking of the illegal drug methamphetamine. A key part of the law was the Federal Controlled Substances Act, Title VII of the Patriot Act and the Combat Methamphetamine Epidemic Act of 2005 (CMEA). What did happen and why?
