So, let me see if I have the facts straight:

-There's a chance it won't make it past customs, but it might, and the orderer won't get in trouble even if it does get found;

-San Pedro can be eaten, powdered and then eaten, or extracted into water;

-DMT extraction is a pain.

As for DMT, would an ayahuasca brew be easier to make than an extraction of smokable DMT crystal?
-It will probably get past customs and as far as I know all they do is inform you they found something
-Correct.
-Very correct.
-I would assume the brew would be easier, yes, but I dont know.
