US federal aggregate production quotas for psychedelic substances, 2013 to 2026

<p dir="ltr">Established aggregate production quotas set by the US Drug Enforcement Administration for psilocybin, psilocyn, MDMA, dimethyltryptamine, LSD, mescaline, ibogaine and marijuana, 2013 to 2026, compiled from the Federal Register orders establishing each year's quotas, together with the DEA quota history table (final or adjusted figures) for 2016 to 2026. The two series are kept in separate files because they are different measurements: the established quota is set before the year begins and may be revised during the year.

Includes a codebook, a sources table with document numbers and URLs, five figures with the scripts that generate them, and a verification page comparing figure labels with the data and the INCB Green List Schedule I entries across the 35th and 36th editions. Version 0.1 (first public release), 16 September 2026.</p>
