i have been doing research into poisonous plants and i have hit a stone

what is the MOST toxic plant in the world. some websites say it is the
castor bean some say it is the roseary pea but some people say it
deadly nightshade(atropa belladona) i just dont know

Castor bean seems a good candidate, but some other nasties include Oleander
(said to be able to kill if twigs are used as barbecue skewers) and
monkshood (but I'm still here despite my parents having a garden full of
this).

Alnwick garden have a good poisonous plants collection, and apparently
someone was hospitalised after just sniffing the henbane.

I am not surprised. I was there on a warm still summers day and the
smell of it was unpleasant and overpowering. I had to move away from it
while the guide prattled on.

but Nicotiana probably kills more than all the other poisonous plants put
together.

It used to kill the people who smuggled the leaves in olden days (nasty
way to go).
