Don't use kambo at all, period. That shit is seriously dangerous. Edit: had to google rapé. Don't use rapé either, which is just a name for nicotina rustica, a tobacco plant that has a lot more nicotine than normal tobacco. So unless you're a smoker already, it will just make you vomit a lot. And it could even kill you since nicotine is extremely acutely toxic. And in general, I would recommend against travelling to the rainforest to take ayahuasca. It's not going to do anything for you that you can't do with some locally growing mushrooms, or a fitting synthetic drug(2c-b is very safe, for instance). You're much better off integrating and going through the experience with friends and family than a bunch of complete strangers.
