So, after trying this.

It wasn't so painful (I smoke a half leave of brugmansia before hand or right after) then the body loads wasn't bad at all, I felt coming up and then ... Not much going on, I would say I got the threshold effect but no psychedelics effects.

I don't know if I should change the recipe (mix hald of sodium bicarbonate with lime as I've seen in most recipe ?) or maybe these seeds aren't very potent (They were free items from maya, so I cannot blame them if they would give away batch of weak material).
