you can smoke dmt acetate, but it's a lot more difficult to vaporize, and becomes easy to burn. I have done it a couple times, got some moderate effects, but never been able to break through on acetate. It will evap at a far slower rate if it's in acetate form, hence why it is more difficult to break through. And then you become impatient at its slow intake rate, hence why it becomes tempting to add more heat and you end up burning it.
