You're kind of vague with your complaint. Not getting vapor or not getting the smoke high? 160 C is low, but 190 should work. Try 7-7.5 if using the Classic (or around 205 C). You should get plenty of vapor.

If your complaint is that you're not getting the same high, that's to be expected. You do lose out on a couple of sedative compounds that take combustion or near combustion to produce, but mostly what you miss with vapor are smoke by-products. They're not cannabis compounds but toxins like carbon monoxide, benzene, toluene, hydrogen cyanide, etc. They make you dizzy, drowsy, etc. and most people just assume that's part of the mj high. You get a much cleaner effect with vapor.
