Sodium Nitrite is a salt. It says that sodium nitrite is an ingredient along with regular salt and FD & C Red
Yes, but it also clearly says
6.25% sodium nitrite. Notice also that salt is listed first on the ingredient list, which are generally in order of the largest proportion of an ingredient through to the smallest proportion of an ingredient. So that product you link to is a blend of
93.75% regular salt and
only 6.25% sodium nitrite.
As others have tried to point out to you, for suicide purposes you need
pure sodium nitrite on its own, at a purity of
95% or greater.
Read the suicide wiki on SN. Yes, you can use the pink curing salt, but it would take a LOT, there is no guidance listed as to how much water you would need, and you'll have to do your own online research about reported deaths as no one on the forum, as far as I know, has reported attempting with it.
I would personally tend to advise
against giving much credibility to information on the Suicide Wiki, it has had past reports of incorrect information and can be edited by anyone.
I would also be
wary of Suicide Wiki suggestions about attempting using
curing salts in such massive quantities as to theoretically provide a usable proportion of SN.
