28 would be capable of feeling pain until he died. To avoid this problem, the dissent quotes Dr. Zivot’s assertions that pentobarbital might not produce “‘rapid unconsciousness’” and that Mr. Bucklew’s suffering with pentobarbital could be “‘prolonged.’” Post, at 4–6, 13 (quoting App. 233–234). But Dr. Zivot’s statements here, too, fail to specify how long Mr. Bucklew is likely to be able to feel pain. The hard fact is that, when Dr. Zivot was finally compelled to offer a view on this question, his only response was to refer to the horse study. Id., at 195–196. The dissent’s effort to suggest that Dr. Zivot “did not rely exclusively or even heavily on that study,” post, at 7, is belied by (among other things) Mr. Bucklew’s own brief in this Court, which asserted that the twilight stage during which he might feel pain could last “between 52 and 240 seconds,” based entirely on a citation of Dr. Zivot’s incorrect testimony about the horse study. Brief for Petitioner 13.

In sum, even if execution by nitrogen hypoxia were a feasible and readily implemented alternative to the State’s chosen method, Mr. Bucklew has still failed to present any evidence suggesting that it would significantly reduce his risk of pain. For that reason as well, the State was entitled to summary judgment on Mr. Bucklew’s Eighth Amendment claim.
