Yes, it isn’t so difficult to extract the spice. Even SWIM , and he knows nothing about chemistry, was able to do it right without great problems.
Now you are curios to make the experience of "hyperspace", aren’t you?
I remember a post of yours, there you said, that you are experienced with salvia.
So just imagine that you are “transformed” in a sort of “hyperspace-being” living in the hyperspace, but sleeping or dreaming, if you smoke salvia. And imagine you are transformed in a hyperspace being, but awaked, if you smoke dmt. So you have a crude conception, what it means to smoke dmt…although these words can only be a metaphor.
The first time smoke only 20 mg, or so! Stay “in front of the veil” the first (and may be even the second) time! This will calm your nervousness (a little bit….).
For a full breakthrough try to inhale 40 mg with one breathe. For me, the test-tube method works very well. (The tube is plugged. The plug has two drillings, in one of them a thinner glass tube is pushed in, which nearly reaches down to the spice.) It’s no problem to inhale 40 mg with this sort of “pipe” and the smoke isn’t harsh, then vaporised in that way, imho.
I wish you good luck, compadre.
