After some self-experimentation, I’d say that CBN-O is 2-3x stronger than CBN. I’m not sure how long it lasts after ingestion (4-6 hours?), but its effects are mostly gone when I wake up. It’s great stuff to aid sleep.

Now that I’ve experimented with the combo, I would say that cannabis interferes with the profound impartiality of ayahuasca. I enjoy ayahuasca more without cannabis.
