I'm pretty sure what you say about jungle spice protecting the dmt is absolutely true endlessness. I have brown spice from a hot water stb tek and you can pretty much put the flame straight on it and it doesn't burn or go and fire and belch smoke the way pure spice would.

I do understand what the o.p is saying though, if i weigh out a gramme of the brown dmt and a gramme of crystalline dmt the brown dmt is much smaller in size which makes me assume that other alkaloids and fats are adding lots of weight to the dmt. I end up smoking like 80mg of brown spice for the intensity of effects i feel at 40mg of pure spice.

If you want consistent changa then stick to one extraction technique and dont change it.
