Note that in the last thread there is reference to the "recook" of poor material, with some significant
enhancement noted.
As can be postulated from the first referred threads,
racemitization can be accomplished in strong acids and strong bases. It is not totally unreasonable to hypothesize
that the reaction conditions themselves result in some
improvement to the material's steriochemistry.
There have been refs to the salubrious benefit of degrading
adulterants by exposure to strong bases (UF's "deconstructionist" thread)..
Some here may not have the sodium to make the sodium alcoholate referred to, but nobody can't get a lithium battery.
If KOH does the job, the pH 23?? or so of the alcohol and
alkali metal should do so even more thoroughly, while screwing around the direction of the (OH) on the pseudo, and maybe even flip the amine group, though the evidence is not clear in the literature, and Rhodium says not likely.
For that issue, however, it does appear to be directed specifically
in the references utilizing Raney Nickle.

Since Urushibara catalysts are similarly able to do the same things,
maybe the whole interfering construct of the pharmaceutical
pill-fuggers can be brought down.
Meanwhile, though: let there be no mistake. As in some other states, Pseudo will become harder to get..
===========================
So get your melamine camp fire fuel while you can, or your oil of almond:
the time will come when all this fun will be over, and you
will just have common old easy unfugged ephedrine alkaloids to
deal with.
won't that be a drag...
US patent 2608583 Racemization of Amines
Example 5:
The d-isomer of methamphetamine will be racemized
to the racemic mixture when 100g of methamphetamine
is treated with 10g of the catalytic material
comprising of nickel on kieselguhr which
is maintained at 145*c for 10hours.
The product maintains only 15% of
its original optical activity.
