Says Thomas A. Edison:--

“Acrolein is one of the _most terrible drugs_ in its effect on

the human body. The _burning_ of ordinary _cigarette paper always

produces acrolein_. That is what makes the smoke so irritating.

I really believe that it often _makes boys insane_. We sometimes

develop acrolein in this laboratory in our experiments with

glycerine. One whiff of it from the oven drove one of my assistants

out of the building the other day. I _can hardly exaggerate the

dangerous nature of acrolein_, and yet that is what a man or a boy is

dealing with every time he smokes an ordinary Cigarette.”

“_The blood of persons poisoned by the inhalation of illuminating

gas_, rich in carbonic oxide, is found to be _coagulated_ and

_indurated_, and may be pulled in strings from the _veins and

arteries_.

“Owing to the loose structure of the Cigarette, its combustion is

modified and destructive distillation proceeds with combustion, and

owing to the incompleteness of oxidation, carbonic oxide is largely

produced instead of carbonic acid. This carbonic oxide inhaled into

the lungs enters the blood unresisted, and the damage it does is

in direct proportion to the quantities inhaled. _Carbonic oxide

when inhaled in small quantities produces faintness, dizziness,

palpitation of the heart, and a feeling of great heaviness in the

feet and legs._ These are exactly the effects of the Cigarette and

the depression and nervousness which follow as a reaction make the

victim crave some balm or tonic for his malaise. He is then led to

consume the drug in ever increasing quantities.”
