"The Navy has zero tolerance for drug abuse and takes all allegations involving misconduct of our sailors, Navy civilians and family members very seriously," Commander Clay Doss, public affairs officer for the Seventh Fleet, told CNN on Sunday.
"These allegations are still under investigation and it would be inappropriate to comment further."
The daily said the drugs involved included LSD and ecstasy, among others, and that at least a dozen US Navy personnel were under suspicion.
Suspicions that drugs had been sold to Japanese residents means that Japanese authorities were also investigating, it added.
If the drug allegations prove true, it would be the latest in a string of bruising black eyes for the Seventh Fleet, which has seen two of its guided-missile destroyers involved in deadly collisions with cargo vessels in the past year, reports of exhausted crews plagued by poor morale, and dozens of its former officers entangled in a Pacific-wide corruption scandal.
