Ricin is a poison which you can easily extract out of castor beans, which are easily obtained as they are completely legal to buy.
One whiff of ricin and you are doomed to die, so I figured extracting the ricin without using any safety precautions like a chemist would, is an easy death.
From the research i've just done it doesn't sound like the best way to go tbh, reminds me of most ODs, because you die due to various organ failures and/or nervous system problems, and it could take a while for the effects to happen due to the reasons for it being toxic in the first place (stops the cells from producing proteins).
I mean, this could definitely work just fine for suicide, but to me it doesn't sound much better than most meds ODs, since it seems to have pretty much the same issues.
However, i could be wrong, most toxicity reports seem to be of people ingesting it by mistake.
Someone willingly ingesting large quantities of ricin could have a different effect, tho i'm not too hopeful it would. So, personally, i wouldn't recommend it.
Still, thnx for the heads up, it's always nice to try to find new methods.
Also, it seems you're pretty new here, so, Welcome!
