WASHINGTON (AP) - The Drug Enforcement Administration has rejected a petition by a University of Massachusetts-Amherst professor to let him grow marijuana for medical research.
DEA spokesman Garrison Courtney on Monday confirmed the agency's ruling, but declined further comment.
Horticulturist Lyle Craker in 2001 submitted an application as a marijuana manufacturer to the DEA.
A federal administrative law judge in 2007 recommended to the DEA that it grant Craker's application to grow marijuana in bulk for use by scientists in Food and Drug Administration-approved research. The nonbinding ruling said the government's supply was inadequate for medical research.
