I am going to be doing such experiments myself in the next coming weeks, but I was wondering how hard the actual goo itself is to vaporize? People have said that it is somewhat hard to smoke, hence making changa, but wouldn't rolling it in some ash suffice just as well to solidify the consistency?

its a little messy to handle, and its more susceptible to being pyrolyzed when un-infused into leaf.

but you could vape this just as well as you could any other dmt.
