Two employees at the Denver Police Department's crime lab are recovering after they were exposed to synthetic cannabinoid powder.

Department spokesman Matt Murray told KMGH-TV that the employees, whose names have not been released, were working with the synthetic marijuana Monday morning when the package burst and both of them inhaled it.

The employees were hospitalized, but their conditions have not been released.

One of them is an intern from Metropolitan State University.
