If you don't exhale any smoke, it could mean your lungs absorbed it all/all the carbon in the smoke stuck to the inside of your lungs (FUCKING NOT GOOD!)

The only reason smoke is visible is because of tiny carbon particles so small they float like all those little white things you can sometimes see floating in any room. If your waterfall was full of smoke that all went in to your lungs and no visible smoke came out, you just gave your lungs a nice layer of carbon :thumbsup:
