reading through this, everyone does realise that "mouth inhalers" do inhale into their lungs right. The difference between the two is like the difference between drinking a pint and dowining it, both still get the drink into your stomach.
I think the difference is in how long the vapor is spending in your mouth, vs. in your lungs. (Assuming that the nicotine in the vapor is absorbed more efficiently by the lungs than the mouth, as is the case with cigarette smoke.) Of course, that assumption is based on another assumption - that mouth-inhalers take drags of the same duration as lung-inhalers, and hold the vapor for the same amount of time before exhaling. Since I'd never heard of mouth-inhaling until yesterday, I have no idea if that's the case. Drag duration varies so much among smokers anyway that it might be impossible to tell.

This is confusing. If you're breathing at the same time that you're taking vapor into your mouth, then aren't you lung inhaling? Or is there a way to keep the vapor separate from the air you're breathing, such that the air goes into your lungs while the vapor stays in your mouth?
Because that sounds like a really neat trick...
