Energy Control has a license to work with controlled substances afaik. The samples can be submitted more or less anonymously. So I don't see the legality issue being that big of deal in this case.
Here is kinda what I have in mind:
A list of available samples is created, we could maintain this list privately to protect anonymity.
When enough money becomes available via donations to run to run a sample we have the person with the sample send it anonymously directly to the lab.
The lab runs the sample and sends the results to a designated person who posts them online.
When enough money comes in for another sample it's sent off, and so on.
A few ideas I have in mind about what kind of samples we could test:
We could test phalaris arundinacea from different climates/locations and check for alkaloid differences. We could find out what alks are in wild aquatica/paradoxa/canariensis/etc... We could look at what alkaloids are present in digitaria species or in a whole variety of other grass species.
We could test what alkaloids are present in various cacti like lophophora alberto/koehresii/fricii etc... What alkaloids are present in the various "brands" of trichs and in other species such as myrtillocactus.
How does the alkaloid profile and concentration of trichocereus bridgesii monstrose compare to standard T. bridgesii and L. williamsii?
Is ibogaine really present in star jasmine?
and so on and so forth
