Tesla invented an ozone production method that produced only ozone, which
is not toxic. The glass electrodes of a violet wand, also a Tesla
invention I understand, produces ozone without the nitric compounds.

Hi Gary,

From "Modern Chemistry" H.C.Metcalfe et. al. 1982:
"Ozone is a poisonous, blue gas with an irritating and pungent odor."
"The presence of ozone in amounts over 0.25 PPM ... can cause chest pain, 
coughing, headache, and eye irritation."

From Chemistry - A Study of Matter" A.B.Garrett et.al. 1972:
"Even in 1 PPM concentration, ozone can cause bronchial irritation."

From "Essentials of General Chemistry" Hopkins and Bailar 1946:
"In considering ozone for any such [deodorizing] use, however, it should be 
borne in mind that this gas is an active poison."

From "Handbook of Chemistry & Physics 77th ed." 1997:
The threshold limit Value for Ozone is 0.1 PPM. This is ceiling value, not 
to be exceeded even for short periods.

From "Handbook of Chemistry and Physics 44th ed." 1960
"Toxicity of Some Gasses and Vapors"
Lists ozone as 1 PPM or 0.002 mg/l

From these, it would seem that the existence of non-toxic ozone is doubtful.
If there is a "non-toxic" form of ozone, it was unknown to the general 
scientific community as recently as 1997. Of course, as one of my chemistry 
professors said, "If you have any doubts, stick your head under the vent 
hood and take several deep draughts."
