Partnership for a Drug Free America has an on-line community called "Parent Partners". Membership is free, and with it parents can get an eNewsletter, announcements about regional programs and events, and email alerts about current drug trends. Parents can also participate in discussion forums and share their own stories about substance abuse, treatment, and recovery.

"...email newsletters are generally sent monthly and contain helpful prevention and intervention tips, local and national news items and events, and alerts about emerging or re-emerging illicit drugs."

You can sign up at the Partnership web site.
