I just recently made my first batch of changa, I used 20 grams of red vine but I boiled it instead of soaking it in alcohol. After boiling i reduced it in a crockpot and right before it became thick I added my mullein and left this while scraping around on low until the herb was infused. Then I dissolved my dmt in acetone and left the herb with it in a shotglass. Making just over 2 grams a third of which by weight was dmt.
