Sorry but new nexian...Not know much of changa
what if not dissolve the freebase DMT and just smoke DMT with the herb in my machine (I'm thinking of some salvia home made extract about 10x) Is it not changa?
I'm a bit worried about the density of spice on the leafs and that it might be hard to calculate how much to smoke. How much salvia should I use for 10-20-30mg of DMT?. I'm worried of dissolving my precious spice. Please help what to do..

The spice needs vaporising, Salvia's best via direct combustion, which doesn't make for a good mix. Also the headspace that your Salvia-DMT mix would produce makes me shudder just to think about it.

Why not experiment with just a small qnt of spice disolved very easily in acetone, then add equivalent or double qnt. of herbs. Everybody has their own ways of doing "Changa".
I like , Blue Lotus, Calea, Passiflora, Banisteriopsis extract. Important that the herb is infused with the spice.

Sorry for the persistence but I have to ask a technical question once more. Why solve the DMT and not just put DMT n' Blue lotus in the pipe and smoalke it?
If I solve DMT wont a small part of it be wasted in the containers edges?

Ok I think I made my first changa 111mg of spice solved in 4ml of aceton, after that I've added 217mg of blue lotus flower. Now it's all in the lotus leaves I weighed about 320mg of changa. But what's next? How much of this is a single dose? I'm quite new with this stuff and have experience of 10mg of freebase. Any suggestions?

A.) Pack a bowl full and chief it until departure.

B.) Weigh out ~50mg of the enhanced leaf, vaporize all of it, and work your way up from there.

Start small work up , its simple , find what works for you
Trial and error method

Ok done it...first flight in hyperspace at 70mg of changa with a real big hit(left only a few in the bowl).
Thanks so much guys . It realy worth anything I did to get this trip.
Some words about the experience:
An other dimension. Felt lots of other superior beings around. Tride to see them but did'nt let me or didn't want to show. In the beggining they tested me if I was ready to enter there world and made me feel a bit anxious I consetrated on my breath and past the test. The prize was to let me see there world but would'nt alow me bring most of the specifics of things I saw. Colourful world, lots of love, talking seems to be telepathetic and through feelings, I had a feeling it was a alien working place. Smooth come back. Hope it lasted some more.
PS My wife sead the blue lotus changa smells like roasted meet
