I see nothing wrong with this. I know, I know.....I'm the angel of death.
So why not just jump in a river or something? Why manufacure drugs in a home lab?
Let's hear the argument for this one. Oh yes, too much of an invalid to throw themselves off a bridge, but they can be pretend home phamacists instead. Knives, razorblades, or overdoses of the many drugs they are probably on just won't work...
Also, as pointed out, what's the point of testing for "impurities"? Afraid of a "bad death"?
