Ozone, what do folks know?

Okay, so the most common thing that everyone says first is "It's that layer with the hole in it, right?" Some other things I got were "We're wrecking it with pollution" "There's a hole from CFC's" and a whole string of thoughts revolving around that same concept. There's holes, holes that are getting bigger. It protects us from the sun's rays, but not if there are big holes in it. It doesn't seem as though there are a lot of people who think about ozone outside of the stratosphere, or in our troposphere.
Only one person talked about ozone outside of the stratosphere, and that was to discuss the strange sounding "ozone therapy". With a little investigation, I found that ozone therapy is being used in many different ways to handle many different ills. It is used to inject and infuse into people because it apparently increases the amount of antioxidants a person produces, it is also used as an antibacterial and anti fungal, an anti-a-lotta-stuff I guess. They are even selling ozone producing machines to have in your home so you can combat your many ills. That seems like a bad idea to me, people adding this unstable ozone, which we know to be toxic, into their homes for . . . ? It isn't clear EXACTLY what people are doing with all this ozone that they can make at home. Adding to the smog problem? Exposing themselves to a toxic gas? This whole idea is a little unsettling. None of the ads I saw said anything about ozone being toxic. It this incredibly irresponsible of the people creating and distributing these products?
