Using the Internet, people working to fight substance abuse can gather the information they need to write grant proposals, develop strategies and media campaigns, and contact legislators. The Internet also connects those working on similar issues, enhancing substance abuse education and prevention efforts. This Monthly Action Kit is a roadmap to the Web's resources. Accessing a few well-chosen websites once a week gives the user a way to maximize funding research without wasting time and effort. The Internet also makes it easier to keep up with research, national news, and current issues in the fields related to substance abuse prevention. Although advocating for legislative change creates the most pressing need for Internet capability, other advocacy efforts, including influencing industry practices and government policymaking, also benefit greatly from it. In addition, the Internet can put the user in direct contact with others who are working on substance abuse issues. Specific advice is offered for getting online and finding useful websites. A list of 48 websites mentioned in this kit is included. (SLD)
