I just heard from someone who used to be a dive master and is now in medical school (not here, he's in the States).
He has told me that there is a correlation between using a snorkel and CO2. What he said was because when a swimmer or snorkeler breathes in and out and because of the width and length of the snorkel tube, that CO2 remains in the bottom of the snorkel so when the swimmer/snorkeler takes each breath, he is inhaling the remains of CO2. This is not a good thing.
Is this why, maybe, that when using a snorkel it appears a swimmer/snorkeler can't get a good breath? I also know that because of the small tubing size, it is hard to really hard to inhale a lot of air, or at least that has been my problem. But CO2?
Is this why when using a snorkel for swimming or snorkeling, breathing can be difficult for some? I know Warren said he uses one, I'd be interested to hear if he has found any problems with using it.
Anyone else?

I use a snorkel when I swim on my own--since during practices the intervals tend to be too fast for me to catch my breath using the snorkel.
They advertise that the use of a swim snorkel consistently (aka...during all types of sets...not just kick and drill) will enhance your lung capacity or build up your lungs (not the technically advertisment slang). I definatly do feel like I have a harder time catching my breath when I am using it, but it also I do feel made me less of an air gulper without the snorkel!
