Please note, it has been my experience in two states, MO and OR that while

exempt quantities apply to a device, they also apply to a specific facility.

A university cannot just acquire as many devices of an exempt nature as it

wants because the total sum of the activity would be above the exempt

quantity for the facility.



Another note is that there is no such thing as an exempt quantity for any of

the broad licensee categories, again because the total could exceed

possession limits.
