If I smoked a bowl of caapi leaf, then made a caapi/spice sandwich (way better than pb&j IMO) will I notice a difference from smoking freebase, say on a bed of mullein? Is the mao inhibition that good when smoked?

MAO inhibition occurs in the stomach, smoking harmalas go straight to the brain and this is why you need significantly less when dosed this way. That's why just simply smoking a caapi leaf produces psychoactive effects. Yes, you will notice a difference, one that I highly recommend.

Thank you house! This is why your awesome <3
I mean there are plenty of other reasons, but thank you!

You're welcome. You can even infuse the spice onto the caapi leaf, and you have changa.

I use caapi leaves, mullein, some white sage, and lavender to compose my changa. It's an incredible thing to smoke or vape.

I now officially made my first changa.
One caapi leaf (yes one) rubbed all over with spice and then melted with a lightbulb.
I'm going to test it in a few min. I will let you know how it goes.

It went very well. I totally understand the 'power' and 'light' references.
I saw a female figure form on my wooden floor boards and smile at me, then a lime green haze of tiny bubbles and patterns (which at the time I took to be the information stored inside the once living wood) arose from the floor and I wafted it around until the patterns in the air covered my arms.
Then I watched tiny south American shamans line dance with Indian gods along my walls.

Spice was like a book and the caapi was like the light you need to see it.
