Hi there, after this search:

google:

zinc -womens -shoes -trousers -capsules -tablets -health -human -diet -coat -oxide -spray -shoes -tape -pot -plated -tablet -tablets -capsules -aerosol -extractor -mask -deficient

swim found various small zinc items, (mostly screws, bolts, etc)

and swim wonders if these things can be used (perhaps filed into zinc filings) to convert dmt n-oxide back to dmt freebase.
