Actaully you can..I have done it and it works, ending with a waxy, crayon like sort of of red stuff, that was potent and breakthrough is possible..It's not as pure as a np solvent extraction though and the yields are not as good.
You have to get all the steps right and not skip out or it will not work you well. DO 3 acid water boils on the bark and combine them all into one large jar and stickit in the fridge for a day to let sediments drop out of solution..then filter out the purple water..ut sould be a clear purple not all murkey red..
Then evaporate this acid watr extact down to purple shiny bark crystals..grind that up into a powder..add sodium carb and water to freebase it..let that dry..then do a few pulls with iso letting each one pull for a while..filter out the iso and add the pulls together and get an eye dropper or baster or something..once all the sediment has dropped otu of solution remove the clear yellowy orange iso, and be careful not to suck up the sediment with it, it will just mae it more impure..
Then evaporate it onto some leaf material with harmalas for changa. if you use 100g of bark dont evap it onto more than 1 gram of leaf..probmore like.6 grams of leaf..you wont get 2% yield this way at all..but it does work and can be quite potent.
That was the first tek I ever did before I moved onto to A/B teksa few years ago..and Ive done it since then as well..but only to make changa..you dont want to smoke this stuff unless its evapped onto a leaf..its like trying to vape a chunk of pastell or something.
If you can id just pull with a np solvent though.
