I have often had this debate with myself as well.

When vaping (sometimes with regular smoke as well) I tend to take a rip, then pull in a few breaths of clean air ontop of the smoke. This not only presses the smoke further into your lungs, but mixes in a bit of fresh air. To exhale I breahte out for a second or so, pull in more fresh air and then exhale the rest of the hit.

I have found this to feel cleaner and mroe efficient than simply holding in fat bong rips.

I do however find it frusterating when people tell you how to smoke pot or criticize you for not holding in hits. different tokes for different folks :jointsmile:
