Different people respond differently to changa spliffs... 25% DMT Changa is what I normally use, which is not considered to be weak, and I don't use harmalas or 10X Caapi to the Changa, just 30% Caapi leaf and/or vine in the blend.

With that, some people are going to take one puff and go interdimensional. And of course, say if you are in a group and passing the spilff around, because of the MAOI's, you are going to get a bonus boost when you smoke the spliff the 2nd time around. And then, if you do another one, in 15-20 minutes, that next one is going to be stronger because of increased MAOI levels in the brain!
