I don’t think ricin is hard to obtain...my wife grows the plant in our yard it is derived from. I think it is difficult to get into a form that can be used to kill people without killing yourself, unless you know what you are doing.
My wife does occasionally say to me in a sweet voice, when I am being an unreasonable jerk:
“Why don’t you have a seat and rest a while, I’ll make you a nice cup of tea...”
Ricin, by that I mean the finished poisenous product; is not that easily obtained or made from the seeds of he castor oil plant. It is somewhat of a lengthy process of extracting the poison by means of the proper solvent followed by repetitive steps in compounding and enriching such a solution. Enough said before someone gets some crazy ideas. And yes I am familiar with that plant, as it is nice to look at and so are many others without realizing how poisenous they are be like for example Oleander. Oh well, I wouldn’t touch it with a ten foot pole.
Aside from hat have a great day and stay healthy and well and if need be have your wife fix you some chamomille tea which is extremely soothing to your stomach and calming to your body.
