I have an idea, that *might* be a potential alternative to SN. Please have a read and if there are any doctors/scientists on the forum, please let me know your thoughts!
So, the ingestion of SN leads to methemoglobinemia, right? After doing a bit of research I ordered a 250g tub of SN from APC Pure, which I have stored in my kitchen drawer as my 'back up' method / potential additional method in addition to CO poisoning.
After re-reading the PPeH, doing further research and also keeping an eye on this thread, I almost am talking myself out of making use of the SN. I feel like there are too many variables to consider, and the possibility of vomiting and pain are major factors.
Doing further research, I stumbled upon what *seems* like a less invasive way to produce the same result (methemoglobinemia).
Benzocaine.
Some info I have gleaned from Wiki-
"The topical use of higher concentration (14-20%) benzocaine spray products applied to the mouth or mucous membranes has been found to be a cause of
methemoglobinemia, a disorder in which the amount of oxygen carried by the blood is greatly reduced."
"Symptoms of methemoglobinemia usually occur within minutes to hours of applying benzocaine, and can occur upon the first-time use or after additional use."
Info from rxlist- "An
overdose of
benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops)."
Benzocaine sprays/gels can be bought OTC easily and cheaply. It wouldn't require a great deal of planning (no anti-emetic regimen to worry about) and you wouldn't need acid reducers for the stomach (as it is absorbed directly into the bloodstream via the skin). I think there's also the elimination of the fear factor, rubbing gel onto your skin seems quite therapeutic as opposed to swallowing the SN diluted with water.
The only thing would be to determine an optimum lethal dosage using benzocaine as a method.
