Humidors regulate humidity levels, ensuring wraps stay moist and pliable without becoming too damp

There should be some better design, more confounders considered and longitudinal studies to be performed to investigate how tobacco smoke exposure affects the epilepsy network
As for using a static smoke, like a single VDB volume frame from a simulation, is sort of the way to go for the actual formation mostly, if you have used vortex forces the right way together with that, but the difficulat part is to shade it similar to as if you wuld use the mesh to volume technique, with normal fluid smoke and vdb, the density of the smoke is pretty much the same or concetrated from the center of the fluid emission, its very hard to adjust the shading in density or in emission to have the sharp edges you see in the mesh to volume example I showed
