I would like to strictly talk about the suitability of Fentanyl as a means of ending ones life. We want to reasonably consider painless and reliable methods so we should talk reasonably about the pros and cons of Fentanyl. I encourage you to engage to overcome the concerns.
1.What is Fentanyl?
Fentanyl is an opiod that has a strong agonist effect on the opiod receptors in the brain. It is medically used as an analgesic (painkiller) and is 100 x as potent as morphine.
2. How does Fentanyl kill?
Ingested in large amounts it leads to a lethal depression of the respiratory function. So it leads to a suspension of breathing or apnea, as we taxi drivers call it.
3. What is the lethal dose?
3 mg when taken intravenously (minimum, use more); larger doses will be needed for a reliably lethal oral administration. THE PURITY IS BIG FACTOR HERE!
4. Is it Painful?
In peacuful Pill the author only writes that is has sedative properties and it can be painless and quick. Although Pieter Admiraal wrote that it should be taken with 300 mg of long acting benzos since one could experience suffocation while still alive. But when done right its a peaceful death.
5. Fentanyl Patches
In "Guide to a humane self-chosen death" the author writes:
"…500 micrograms per hour as the lethal dose. Duragesic transdermal patches with a combined dose of 500 micrograms should be applied simultaniously on … skin."
-PURITY: Its possible that people on the darknet sell impure stuff that is not lethal or needs to be taken in other quantities.
-SPEED: Very few infos available. PPH rates speed with 3/5. Pieter Admiraal states that it might take up to 24 hours till death occurs. That refers to the patches, though. Its still important since you could be "saved".
-INGESTION: I dont know what is the best here: oral, intavenous or patches. I dont know the pros and cons of that.
-ANTIEMITICS: They prevent you from puking the poison out. I dont know if its necessary here or which stuff to take.
-SEDATIVES: PPH states that it sedates you, Pieter Admiraal recommends taking benzos to not to experience suffocation consciously
How about some grapefruit juice?
Fentanyl is rapidly metabolized by a liver enzyme. Products that interfere with the enzymatic breakdown of the drug can increase blood levels of the drug. Grapefruit juice may result in a potentially dangerous increase in Fentanyl concentrations. This may cause fatal respiratory depression. (excerpts from peacefull pill)
CARFENTANIL is 10000 x as strong as morphine. In PPH ,after talking about the lethal Fentanyl doses, is stated "For Carfentanil, even smaller doses will end life"
