Today i tried vaporizing a little amount of freebase harmalas at about 190-200 degree celsius and immediately felt cold like i also do when vaporizing spice. After some draws i felt a bit lightheaded, more attentive and maybe even a little nausea.
What i noticed is the similar taste it has to oral taken harmala hcl , which is a real bitter taste for me.
It also seems that even at 200 degrees celsius the freebase harmalas do not seem to be even nearly completly vaporized , so that makes now me also fear that changa might not work with my vaporizer, because of the spice vaporizing already at about 160 degrees.

Is it normal that pure freebase harmala tastes exactly like oral taken harmala hcl?
Must i use a smoking device that uses a flame or torch lighter for changa to work?

Another big problem i have is, that i does not matter what i vaporize , be it spice or harmalas i always get uncomfortably cold and dizzy very quick, alltough the room i am in is relatively warm or at least warm enough to sit in comfortably wearing only a shirt. Because of this i than get even more nervous than i already am (until now i have no real success with vaporized spice)and can´t take deep enough breaths of the spice to feel much of it´s effects. The room i am in by the way is quiet and i am undisturbed for hours if i want to, so noise is not the problem.
Is it normal to get that cold and dizzy while vaporzing spice?
It feels more like i am sitting outside than in a heated room, i also can not stop shaking.
I go from i am completly ready and excited for the experience to nearly panicking and thinking something like what have i done to myself.

I recently smoalked some harmala freebase on its own. The taste that I noticed was reminiscent of the taste of a burning cannabis seed.
