The Minnesota Department of Health says reports of Rohypnol, or "the date rape drug" are still uncommon in Minnesota, but there's concern because the small number here is growing. Hennepin County has seen about a dozen possible cases in the last year -- four in the last month. The drug is usually slipped into a woman's drink leaving her incapacitated and unable to remember what happened. Doctor Linda LeDray, of Hennepin County's Sexual Assault Resource Center, says she suspects incidence of the drug is STILL under-reported.
