Kiap, I think getting an acupuncture certificate is the best thing you can do, then you could always work with acupuncture and bring Kambo in when someone is interested or when you see need, however, I'm sure it would be considered a bit unorthodox and you would still have to mind your p's and q's.
I have a few questions, how often do you treat people?
Is kambo a big source of income for you?
Is this something you do mostly in your freetime?
Why do you feel taken advantage of if you do someone a freebie?
I can sort of understand charging if it takes up a lot of your time, but if your feeling taken advantage of for doing it as a favor, perhaps your treating the wrong folks and should re-evaluate your intentions.
Honestly I have yet to administer Kambo to anyone other than myself, people seem pretty weary of it, besides it is not just for anyone.
I personally think it would be an amazing life and way to make a living, but what protocols have.you set in place in case something goes wrong? Realizing that if something did go wrong, it could draw unwanted attention to the medicine?
Entheogens are my 3rd love, first is god my higher power, second is my love for my beothers and sisters, and in order to keep this all going I have to do things I don't much like....work, but this is why im going back to school for biology and botany so maybe one day i can do what i love for a living.
