In what ratio did you make this changa, as far as DMT-leaf goes?
1:1 ratio?
Even so, imo just load 100mg of the blend, put into a pipe, take long slow drags, holding each for 15+, repeat until repeatability is no more. Not that you'd have to smoke the entire amount; it's just so you will have more than enough to toke on until your dissolved.

Happy Halloween!
