I read this study a while back but decided against posting it. I felt that some people feel encouraged or justified drinking and diving.
Also, regarding to the comments on vasodilation: if you look at the Viagra study, it increased your risk of oxygen toxicity and DCS! It also demonstrated that vasodilation is NOT prevention for DCS and that the protection nitric oxide gives is more complicated than its effect of vasodilation.

A fair point, but I would hope everyone would take this for what it is, which is an experiment that tells you something about a few rats treated in a particular way in a single study under specific conditions and it should not be used to justify any sort of human behavior. That is probably too much to ask as people generally only look at these things to support/justify existing or desired behaviors even in the face of common sense. People will do what they want, even in the face of lots of evidence that it isn't good for them. I suspect that anyone who would use this to justify drinking and diving already has about 10 other justifications and if this study supported the opposite proposition they would just ignore it in favor of the other 10.
True, but neither should it be discounted entirely for the same reason. Perhaps a diver who already engages in alcohol consumption prior to diving might know they need have less anxiety about their activities.
A lot of diving seems to be based on theory and guesswork. Discounting any formal study, even a limited one, seems like a big waste. Hell, even decompression its-self is still just theory, right?
That said, I don't drink before diving. Not because of any direct influence it might have had on decompression. Mainly because I don't want to make bad decision underwater and also because I dive early in the morning, long before I'm ready for a drink.
