There are several opinions: botox, cyanide, and plutonium.
Botox
It's the most toxic substance known.
yes
Botulinum toxin is a toxin produced by the bacteria Clostridium botulinum; it is the most toxic substance known today.
That's totally wrong, the most toxic substance known to man is Botulin toxin, from the bacteria Clostridium botulinum. Botulin is approx 1000 times more toxic than TCDD, and TCDD is also less toxic than polonium 210. No man made substance has come close to beating the toxicity of a certain bacteria Botulin is commonly known under the trade name of "botox" so when you're having that injected into your face remember this
The problem with chocolate is that it contains a substance known as theobromine, and this substance is toxic to dogs but not to humans.
the most toxic substance on earth is botox, people inject it under their skin because it kills the wrinkles

my brothers.

Known as the Irish Strawberry Tree it is moderately toxic to goats and toxic to most other animal species.
It's a toxin produced by a bacterium... Botulinum toxin is the most acutely toxic substance known, with a lethal dose of about 200-300 picogram of toxin per kg of bodyweight. It is the toxic compound produced by the bacterium Clostridium botulinum. A picogram is One-trillionth (1x10-12 or 0.000000000001) of a gram. This means that 100 grams would be enough to kill all human beings on earth. Ralph Nader, noted environmental activist, once claimed that plutonium was "the most toxic substance known to mankind", but this is not correct. Polonium (for example) is more toxic than Plutonium. By mass, polonium-210 is around 250,000 times more toxic than hydrogen cyanide (the actual LD50 for Po is about 1 microgram for an 80 kg person, compared with about 250 milligrams for hydrogen cyanide)
