Quote
“When Prof. Craker obtains his license, MAPS will have a viable source of cannabis for drug development research. That sea-change, alongside obtaining a $10 million grant for our marijuana/PTSD research in vets from the State of Michigan and final approval for publication of the results of our first marijuana/PTSD study, will uncork a decades-long backlog of research into the medical and mental health benefits of cannabis.”
Winter 2021 column. Expectation that Lyle Craker will obtain a DEA cannabis cultivation license and that this plus a Michigan grant will open cannabis drug-development research.
Intake
- EventA proposition written from a template on the asset, with a resolution criterion and a named public source, before the outcome is looked up. The same event resolves every person's items on it. Method ›
- DEA registers Prof. Lyle Craker to manufacture cannabis for research
- AreaOne of five topic classes: regulatory decisions, clinical trial outcomes, company and market outcomes, payer and policy, practice adoption. Every event has one area. Method ›
- Regulatory decisions
- DeadlineThe date by which the event must happen for the item to be true. It comes only from the person's words through the anchor table. Method ›
- None stated · undated panelItems with no deadline in the person's words, scored on a uniform 24-month window from the statement date. Part of the headline panel since rules 1.1.0; also shown on its own. Method ›, 24-month window to 15 Mar 2023
- Probability
- 0.90 LexiconThe fixed five-bin table that turns a phrase into a probability. The strongest phrase in the claim sentence decides; coders never read tone. Method › · binOne of five lexicon steps: A 'will' 0.90, B 'probably' 0.70, C 'may' 0.50, D 'unlikely' 0.30, E 'never' 0.10. A stated number goes to the nearest bin for calibration only. Method › A · “When Prof. Craker obtains his license, MAPS will have a viable source of cannabis”
- Base rateThe probability a published external study gives an event of that class and stage, fixed at intake. Halved when the item window is shorter than the class median time to decision. Never learned from the ledger's own items. Method ›

Registry entry
The DEA grants Prof. Lyle Craker (University of Massachusetts Amherst) a Schedule I manufacturer registration to produce marijuana for research.
TRUE on the date the DEA issues a Schedule I bulk manufacturer registration to Prof. Lyle Craker, or to the University of Massachusetts Amherst facility he directs, for the manufacture of marijuana for research, as published in the Federal Register or announced by the DEA Diversion Control Division. A DEA policy statement that it will accept applications, an acceptance of an application for filing, or a court or administration order directing the DEA to act is not a registration. Resolution source: the Federal Register DEA registration notices. FALSE at the deadline when no such registration has been issued.
Resolution source: Federal Register (DEA registration notices); DEA Diversion Control Division announcements
Readings: 'Order the DEA to ... issue a license to Prof. Craker' resolves on the DEA registration itself, whoever ordered it; the administration's order is the means, the registration the outcome.; The words tie the registration to the end of the NIDA monopoly on research cannabis supply; the registration of Craker is the outcome this entry holds.

- Resolver note
- The DEA has never registered Prof. Lyle Craker or a University of Massachusetts Amherst facility as a bulk manufacturer of marihuana. His June 2001 application was denied by the DEA on 2009-01-14. The DEA Notice of Registration lists for bulk manufacturers, 2019 through 2026, contain no University of Massachusetts, Amherst or Craker entry, and the DEA marihuana growers page lists seven registered growers, none of them UMass. Craker died in May 2022. Not resolved by inference: this is the DEA's own registration record as of 2026-09-14.
