Extraction of chemicals or drugs from plants or OTC products always belongs in "Chemicals & Equipment", unless it is specifically intended for the manufacture of meth, in which case it goes in the Stimulants forum.
If you read the sticky post in the Tryptamine Forum ( Post 412519 (https://www.thevespiary.org/talk/index.php?topic=12794.msg41251900#msg41251900)
(Lilienthal: "Tryptamine forum improvements", Tryptamine Chemistry) ), you'll see that extractions and shroom growing are depreceated in that forum, as it was originally created for the discussion of the synthesis of tryptamines and lysergide derivatives.
Extraction of alkaloids is most definitely something classified as "Basic Chemistry & Techniques" rather than "Drug Related Chemistry", if you look at the broad categories on the front page.
