Hello friend!
Sounds like you are in for an adventure!
From my experience and understanding, caapi alone is subtle yet meditative unless a large dose is used, at that point caapi is very psychedelic(most intense through oral ingestion) I would personally recommend getting the feel for caapi if you are curious about what caapi alone has to offer, which is very much! Caapi is a beautiful teacher on her own.
With that said, I see no harm in taking a small hit of caapi at the peak and wait to see how you feel. Since you are smoking it, the effects should be relatively quick. Its all up to you on how much you'd like to potentiate the mushroom journey.
So, overall I would say start small when trying to potentiate the mushrooms but theres no real health dangers to worry about.
Again, I do suggest to get the feel for what caapi can offer on its own.
Happy journeys!
Peace and love!
