Customs and Border Protection authorities on Wednesday announced the seizure in El Paso at the Ysleta (is-LAYT'-uh) commercial cargo site.
A drug-sniffing dog on Tuesday drew attention to the load.
Customs officers discovered that smugglers had cut rectangular spaces into the roofing paper rolls and filled the spaces with bundles of marijuana. Authorities seized more than 1,800 pounds of marijuana.
Nobody has been arrested as the investigation continues.
