Oxygen: a dangerous drug which must be banned.
OXYGEN
Oxygen is a very toxic gas and an extreme fire hazard. It is fatal in
concentrations of as little as 0.000001 p.p.m.. Humans exposed to
these oxygen concentrations die within a few minutes. Symptoms resemble
very much those of cyanide poisoning (blue face, ect.). In higher
concentrations, e.g. 20%, the toxic effect is somewhat delayed and it
takes about 2.5 billion inhalations before death takes place. The
reason for the delay is the difference in the mechanism of the toxic
effect of oxygen in 20% concentration. It apparently contributes to a
complex process called aging, of which very little is known, except
that it is always fatal.
However, the main disadvantage of the 20% oxygen concentration is in
the fact it is habit forming. The first inhalation (occurring at
birth) is sufficient to make oxygen addiction permanent. After that,
any considerable decrease in the daily oxygen doses results in death
with symptoms resembling those of cyanide poisoning.
Oxygen is an extreme fire hazard. All of the fires that were reported
in the continental U.S. for the period of the past 25 years were found
to be due to the presence of this gas in the atmosphere surrounding
the buildings in question.
Oxygen is especially dangerous because it is odorless, colorless and
tasteless, so that its presence can not be readily detected until it
is too late.
