Pfizer has instructed that none of its drugs and medicines be used to kill in assisted suicide. From the company’s press release:
Pfizer strongly objects to the use of its products as lethal injections for capital punishment.
Pfizer’s obligation is to ensure the availability of our products to patients who rely on them for medically necessary purposes. At the same time, we are enforcing a distribution restriction for specific products that have been part of, or considered by some states for their lethal injection protocols.
Oh, executions! Never mind.
Cruel and unusual death with dignity can proceed with no interference from drug companies.
