I would certainly hope that the DEA is aware of his existence, as the DEA granted him a license to grow Schedule 1 "narcotics".
“That led to being covered by a DEA [Drug Enforcement Administration] license to study psilocybin active mushroom species. So, I specialized in the taxonomy of those species, and then, because of the cultivation skills that I gained, I branched out into growing edibles and medicinals, and my mother was much happier.”
Psilocybin is not active, but is converted to active psilocin by dephosphorylation when it is digested. Mushrooms also contain some psilocin. There is active research into the effect of other tryptamines in mushrooms, including, baeocystin, norbaeocystin, and norpsilocin, and others.
