Illicit substance distribution is a massive, fault tolerant, self correcting and self routing network of individuals, you just have to know some people near the edge nodes. This is also why the war on drugs is such an abject failure.

As for this substance I've only had what was described as a "child dose" and enjoyed the absolute tranquility, some friends have had bad trips on much higher doses but as someone that isn't a fan of psychedelics and didn't want any hallucinations I loved that small dose.
