THANKS for the comment, though I know NOTHING about execution by nitrogen.- I do know that HELIUM works painlessly, as it is used for “assisted suicide” OCONUS.
Btw, a great many of us wild & rebellious TEXICANS see “lethal injection” as “UN-Texan”, even if it did NOT have so many potential problems.

From what I have read, Nitrogen is a preferred inert gas; Helium can cause spasms/other negative reactions. Since Nitrogen is the major part of the air we breathe, the body is not susceptible to rejecting it.
