"....they had come up with the technology to be able to track schizophrenia patients as to if they were taking their meds on time."

"...the mRNA was capable of sending messages to the body."

In fact mRNA is a message to the body. It's instructions on how to build proteins. Now, if you can get a message to send a message, you'd have something else besides mRNA. It's getting pretty recursive, though.
