I remember reading about cannabis allowing bacteria to enter deeper into the lining of the digestive system. I'm under the impression the aza is possibly increasing this effect for H.Pylori or something?
I could digest a bowling ball, before I was first poisoned with Azadirachtin 10+ years ago.
I'm almost certain that either azadirachtin is psychoactive on its own or that it binds with the THC, affecting the same parts of the endocannabinoid system and brain but with unwanted effects. This would include just about every organ, but the stomach and intestines are very susceptible. People have been posting for a while that aza weed can induce a more-paranoid-than-usual high. Often it co-occurs with body coldness or chills, and then nausea kicks in.
The hypothalamus is a peanut-sized part of the brain that controls appetite and temperature regulation. It's my suspicion that this is where azadirachtin bioaccumulates, but that's just my own theory.
Before aza, I was also able to eat anything. My GI and metabolism was in excellent condition. Now I barely eat.
