Paregoric Tincture was an Upjohn product containing morphine sulfate. It was sold by the gallon. Carol Orris recalls testing one of the last morphine samples that the Control Labs in Building 41 ever received:

"In the late 1970's the lab got a sample of morphine sulfate to test and it was a huge deal due to DEA regulations.  The sample couldn't come through the Control Sample Center as it had to be under the control of a registered pharmacist.  Luckily the Building 41 company pharmacy was still in existence and the pharmacist there personally handed off the sample to the Control Lab.  We received just enough sample for the required tests and the sample had to be tested in one day by one person. It couldn't be locked in the lab drug drawer and it couldn't leave the lab so there was no break or dinner for me.  I think the original container of morphine sulfate was located downtown."
