I've got some unfermented kanna 50:1 extract from a well known vendor from the Netherlands.
I've insufflated small amounts in each nostril. I made sure each nostril was optimally primed for absorption (by cleaning and ensuring the inside was moist)
The amount was perhaps roughly around 3mm³.
I have not tried any other ROA's (routes of administration)
I feel the PDE4 inhibition (which kind of promotes wakefulness) goes really well with the CB1 agonism and the other properties.
Btw, unfermented kanna contains a wider selection of alkaloids than fermented kanna.
