This topic comes up occasionally here on SaSu. I'm not sure if it's important to you, or not, but, from my recollection, poisonous plants typically don't produce what can be described as a "peaceful" death, even if you managed to consume enough of the plant (poison) and were able to keep it down. Your body is going to very quickly recognize that a poison has been ingested into it and take immediate steps to expel it. I think it's very unlikely that you'd be successful at CTB using this method. What's more likely is that you'd cause yourself significant harm in some way, shape or form, possibly in the form of organ damage of some sort. It's very likely, IMO, that you may add to the misery you're already in, because you'd end up with some significant physical impairment. You *may* end up in such a way whereby you'd be unable to take any action again to remove yourself from this "new" misery you find yourself in, depending on how severely you injured yourself. I don't believe this method has a very high lethality rate.
That's just what I remember about this topic, along with some of my opinion. I'm sure others will chime in.
