The federal Drug Enforcement Administration (DEA) has released notice of proposed rulemaking on Mobile Methadone Vans for public comment. The DEA proposes to revise the existing regulations for narcotic treatment programs (NTPs) to allow a mobile component associated with the registered program to be considered an equivalent activity. The revisions to these regulations are intended to make maintenance or detoxification treatments more widely available, while ensuring that safeguards are in place to reduce the likelihood of diversion.
