Video is broken for me.
My better half is an herbalist, and we have an essential oil distiller like the one linked below, and were talking about using it for cannabis. Seems to me like it should work great! I've read people saying things in regards to steam distillation like, "cannabis is not soluble in water...", but isn't that the whole point? Seems to me that the steam and oils should move through just fine, and then separate out after condensing. Aside from the essential oil, we were also wondering what cannabis hydrosol might be like, and what it could be used for.
What are your results like? Are you using the product for medicine or recreational use?
