What pain is felt in short drop/suspension hanging?

It should be clearly understood that suicide by hanging is likely to be VERY PAINFUL
as there will hardly ever be sufficient drop to break the neck.

Short drop or suspension hanging is, at least initially, likely to be very painful as the person struggles to breathe against the compression of the noose and against the weight of their own body, being supported entirely by the neck and jaw. Houriyeh above exhibited very obvious sings of suffering.While 1 to 3 minutes before unconsciousness sets in may not sound a long time it must feel like an eternity to the suspended and struggling prisoner.

It is sometimes possible to revive a person after short drop/suspension hanging and thus we can have an idea of what they felt. People who have survived hanging have described the pain diminishing after a while and seeing bright lights as they drift into unconsciousness.
An Iranian man identified only as Niazali, was hanged in February 1996 but survived after the victim's relatives pardoned him. He told the Iranian daily newspaper "Kayhan" what it had felt like."That first second lasted like a thousand years. I felt my arms and legs jerking out of control. Up on the gallows in the dark, I was trying to fill my lungs with air, but they were crumpled up like plastic bags." Niazalis hanging reportedly lasted 20 minutes.

Hanging versus Lethal Injection.
Many people who support capital punishment feel that lethal injection is a better, more modern and humane form of execution than hanging. Is this view based upon the facts or is it purely a perception based on the fact that we have experienced (non-lethal) injections ourselves? It is noticeable that the a majority of the American respondents to my surveys cite lethal injection as the method they would choose for themselves, although a considerable minority of British respondents of both sexes chose hanging.
Execution by lethal injection takes much longer than any other method, anything up to 45 minutes for the complete process during which the prisoner is fully conscious except for the last 7-10 of those minutes (remember that in Britain a 20th century hanging took, typically 15-20 seconds to carry out).This duration must subject the prisoner to far more mental torture because they know they are being put to death.Lethal injection is clearly much less dramatic than hanging and, therefore, probably easier for the staff and witnesses to cope with. It is suitable for both sexes and all ages of prisoners where a suitable vein can be located. However, there is often a problem where the prisoner has been an intravenous drug user or simply has small veins which tend to contract even further when they are frightened.
One wonders if lethal injection is perceived as being as much of a deterrent as hanging in the minds of criminals or whether they would feel it was a "soft option"?
This is an important point because if the state is going to take the life of a person at all, then surely it should seek to produce the maximum deterrence from so doing without resorting to cruelty.
