Michael Meyden is accused of making the smoothies with benzodiazepine, a drug typically prescribed for anxiety, according to a probable cause affidavit.

An Oregon man accused of spiking smoothies with sedatives and giving them to his daughter’s pre-teen friends has been charged with multiple felonies, according to court documents.

Michael Meyden, 57, of Lake Oswego, allegedly drugged three of his daughter’s friends while they slept over on the night of Aug. 25, 2023, according to court documents and a probable cause affidavit filed this week in Clackamas County.

The girls, all 12 years old, were hospitalized and tested positive for benzodiazepine, described in the affidavit as a drug typically prescribed for anxiety, with common prescriptions under the names Valium, Xanax and Klonopin. Benzodiazepines are a depressant that produces sedation, sleepiness and a relaxed mood, the affidavit said.
