EAU CLAIRE, Wis. — Law enforcement officials and school administrators in Eau Claire are warning parents and students about an LSD-type drug making its way into western Wisconsin.

Local police say one adult and several juveniles were recently in possession of the drug commonly called N-bomb at North High School. Authorities say it's the first time they've seen the drug in Eau Claire.

KMSP-TV (http://bit.ly/1I1V9U8 ) reports school administrators say the compound drug is a type of synthetic "acid" that's abused by applying the liquid form to blotter paper.

School officials in Lakeville, Minnesota, issued their own warning about the drug in November. The school district sent a letter to families warning that N-bomb was being distributed in Minnesota high schools.

Authorities say the drug took the life of 17-year-old Tara Fitzgerald of Woodbury, Minnesota earlier last year.
