Just got done making my first batch of changa. I infused my herbs with DMT as well as some B Caapi 10x liquid extract that I acquired. Most of the acetone I used seems to be evaporated. It still smells like the liquid extract however which I think may have used whiskey as the solvent for the harmalas. I'm concerned that the whiskey may leave behind residue since the cup I infused the herbs in seems to be quite sticky. Does anyone know if that is the case? Will the changa be safe to smoke if so?
