Cover said another concern is the vagueness about the types of drugs and how they are to be procured. And by state law, a pharmacist has to have a prescription or medical order to prepare, dispense or administer a medication. The lethal injection law says the drug may be dispensed without a prescription upon written request of the Corrections director.

The pharmacists also have concerns about the drug compounding language in the protocol, she said.

"I'm not sure, when this was drafted, if there was any discussion with a medical professional," Cover said.

Sen. Ernie Chambers said recently he intends to go to Friday's hearing, and is concerned about the lack of transparency the protocol allows.

Anything the government does in the name of and on behalf of the people should be done in plain sight, he said, without camouflaging and making it seem like it's something that it's not.
