License of doctor, who provided emergency medical combat training for military, has been temporarily suspended. The Virginia Board of Medicine has alleged that Dr. John H. Hagmann, 59, dosed students with alcohol and ketamine.

After intoxicating them, he made the students to carry out invasive procedures on one another and also exploited them for sexual gratification.

Next week, Hagmann will appear in Richmond for a disciplinary hearing before the board. His company, Deployment Medicine International, is in Washington. He also has a training facility on a farm in Partlow. Investigators for the Board of Medicine came to know that Hagmann has given alcohol, ketamine and other sedatives to at least 10 students.

He termed these sessions to be 'cognition labs'. As per the investigators, the sessions took place in 2012 and 2013. As per the investigators, Hagmann did not take consent from some students before giving them drugs after they had alcohol.

In response to allegations, the doctor stated about his training that it complies, "with standard practices for training medical students and are, in fact, utilized in medical schools in Virginia".

The investigators said that Hagmann made course participants carry out practice inserting catheters into each other in the trainings. It is the first time that he has faced allegations with regard to his treatments of students. Hagmann has denied allegations that he committed the acts for sexual gratification.
