Is the density of ricin so low that a pinhead-sized amount (I assume on the order of 10^-9 m^3) weighs only 0.5 mg? Or does this refer to a different delivery mechanism than injection or inhalation? "Ricin is 6 billion times more toxic than cyanide and 12 billion times more poisonous than rattlesnake venom by weight." This seems very unlikely.
