SWIM's tried out today with the Noble Vapor VP300.
Nothing so interesting, onestly.
SWIM's put up something like 30 mgs (his weigh scale has broken just yesterday, so he can't be that accurate), with a bad of mint, using 1:1 changa spice: peppermint.
He setted on the lowest temperature. After a bit, a very pleasing bit, looking at the sky, vapor starts to be evident in the bowl. Maybe he should have waited more, but he started to inhale. Definetly something came up, but as the bowl is pretty big, for the little vapor produced by spice, he had to do many many inhalation.
Was interesting, though. Only some body and mild mind effect, but lasted quite long. he loves the triptammine body feeling. At the end, he totally felt like he had a good dose of melatonin, and was about to fall asleep.
I think, if you put up like 100 mg spice, and smoke in 2 people, would be a quite strong and long lasting effect.
SWIM has to experiment with that.
