Well, I am a stoner who cant wait even a day without getting stoned, so I have been cutting little leaves off my plants and smoking them without curing or anything. The really wierd thing is that they produce no resin (on the inside of my pipe) its all just water!
When my cousin was dry and I was at his house we smoked probually 50 leaves that he had saved up out of his roor. We werent baked...but we deffently had a nice buzz. They do do somthing. Remeber, the seed is the only part of the plant with no THC. And yeah, its wet cause you didnt dry it out.
Im sure you could if you wanted to. But there is even less thc in the leave then the steam, so it would take a shitload.
