Are pharmacies in Oklahoma required to video monitor their employees who deal with controlled substances?

Not that I can find.

It appears to be at the discretion of the pharmacy. Hidden cameras are becoming more and more common in pharmacies - but you probably already know this.

It would appear ALL pharmacy employees would have to be videoed - I don't know of any Pharmacy where only certain people deal with controlled substances but I suppose it could happen.

Most do, all the major chains that I know of do, Most likely some small family owned places may not.
