So let me clarify, I do not want to try this. It was just a thought experiment and I am wondering if anyone thinks it would work. So let's say you obtained some fairly pure kief using a very fine screen. You bake it in the oven to decarboxylate it. While it is about the same molecular mass of cocaine and most opiates, you couldn't insufflate it now because it is too non-polar to be absorbed through the mucus membrane. Ethanol can be absorbed through the mucous membrane. Thc dissolves in ethanol. If you dissolved Thc in ethanol, it should cross the mucous membrane right? Obviously this would be painful, potentially dangerous, and overall unpleasant compared to smoking, eating or drinking. But just for curiousity's sake, could you insufflate Thc in this manner and get high off of it?
