Why do we need an Addiction supplement focused on methamphetamine?

Methamphetamine is a substantial public health problem in many communities in the United States and in other parts of the world.

The articles contain information presented by researchers at two special methamphetamine meetings sponsored by the National Institute on Drug Abuse in 2005.
