Nitrogen Narcosis and Nitrox

[Web Monkey]

The book also states that the active ingredient in decongestants may act as o2 exciters but it does not state what this ingredient is. I asume its psudoephidrine. Is this correct or are there other drugs too?

I used to take decongestants before diving, but stopped after deciding that diving with a fast heart rate and jacked up blood pressure probably wasn't a good idea.
