Notice that I wasn't suggesting to inhale. I said swallow.
The difference being going into the stomach, not the lungs.
Even breathing ozone will not cause brain damage or I would
have been flopping about my office floor a long time ago. I
have over 8,000 mgs of ozone pouring into my office every hour,
every day with no problem.
Now, granted, I wouldn't 'inhale' ozone directly through a tube.
That would be far too much of a concentration for the lungs to
handle all at once.
