Hi North Star
I still have three Amalgams in my mouth and have done oxygen/ozone/H2O2 therapy for twenty years. I suspect the only reason I'm still in great shape at 57 is because of the oxygen therapies. I also suspect that in my case the oxygen/ozone/H2O2 helped to eliminate the mercury released from Amalgams by oxidation. I still advocate for removal of amalgam. When I had the majority of mine removed, my chronic sinus problems disappeared.
As for drugs,IMHO pharmaceuticals are enhanced by oxygen therapy.
hope this helps,
