Just a heads up- Nasal insufflation is one of the best ROA for kanna extracts, but can be slightly painful.

What I do is mix the kanna extract with a bit of coconut oil, heat gently on a spoon, and snort it after it cools. With this method there is little to no burn, and the coconut oil seems to help with absorption too.

Also, for health and safety reasons, make sure you only use clean solvents and don't leave any residual solvent in your extract.
