The U.S. Drug Enforcement Administration is looking to modify its policies regarding the disposal of powerful medications that long-term care facilities need to discard. Providers, including the American Association of Homes and Services for the Aging, have submitted comments for the DEA's public meeting, which will be held next Wednesday and Thursday in Washington. Among the hottest topics will be the DEA's concern that abusers might devise new and unwanted pathways to re-route controlled substances from intended destruction.
