Not really? If you know how to use TOR you can just order it online. I do this with LSD all the time and it works fine.

In the US at least this seems pretty insane to me while we have a fentanyl epidemic.

I am sure there are ways to test this but I wouldn't trust myself. Not to mention the illegality of it.

At this point, it is simply criminal MDMA is not available for therapy the way ketamine is.

there are reagents that can be used to test. I've never used one because I trust my vendor. LSD is almost never cut with stuff (the illegitimate listings usually completely replace with something stupid like NBOMe). Usually if you get real LSD it's not also adulterated. If my vendor were illegitimate I would have died by now since I've taken up to 16 doses at once before.

I would never put a drug ordered off the internet into my body. Pure lab grade LSD which has been tested in an NMR — I probably would. I only have one body and I wouldn’t entrust it to random people on the internet.

I think you could estimate the risk in micromorts from taking LSD from darkweb and find it’s not that different from other activities you do regularly (~multiple times a year, if not more)

You cannot estimate the risk of taking internet LSD, that is the problem.

There is also a history of cutting drugs with other substances to give them a unique effect which brings back return customers (i.e. cutting heroin with fentanyl).

And then there is the possibility that whoever produced the LSD screwed up and/or the end product is not pure.
