The first hit is the most noticable. However, there is plenty of vapor after the first hit. Even if you can't see it, there is vapor if you use a light. I have a bright LED flashlight and one night I used it to vape in the dark. I could see the vapor and I was getting vapor way after I though it should have been cashed. I even put in ABV and got decent vapor. I let my stem warm up for about 10 seconds before the first hit, and I clear it between hits and let it warm again. With the light I noticed I was loosing vapor if I didn't clear the stem.
If I take 10 -12 hits off a stem and exhale a little and take in some air several times I get a very noticable increase in the effect. I also think that doing 10-12 LONG hits gives it a boost because the glass stem gets hot enough to burn off some of the honey build up toward the bottom of the stem.
