Dennis Hof was the picture of health before his untimely death, and there are no obvious signs he was under the influence when he died ... TMZ has learned.
Law enforcement sources tell us no drugs or alcohol were found near Hof's body Tuesday when paramedics arrived at his Love Ranch home in Crystal, Nevada. An autopsy is scheduled for Wednesday.
Sources close to the late owner of the famous Bunny Ranch brothels say Hof did not drink or take drugs of any kind -- and insist even his signature cigar was fake.
