Re: Craving some Nakhla DA Can
Heba Diffusers don't have a filter of any sort, it's simply a plastic snap on bottom with small holes with a rubberized top that hugs the stem (also with holes). It's a diffuser on the same level as any you could make on your own.
I do own two of them, and I do use it all the time, however in my experience it really doesn't change anything about the buzz. The change in surface area of the bubbles is quite negligable, so a small amount of area is increased but nicotine doesn't get fully absorbed by water like magic. Small amounts do as shown in some studies but still a massive percentage remains in the air and smoke you inhale. Definetly wouldn't solve The Egyptians problem.
