Senior US Senators Edward Kennedy and John Kerry have agreed to send a new letter to DEA Administrator Karen Tandy urging her agency to accept the recommendation of DEA Administrative Law Judge Mary Ellen Bittner to grant a Schedule I license to University of Massachusetts professor Lyle Craker, PhD, for his proposed MAPS-sponsored medical marijuana production facility. An independent supply of research-grade medical marijuana is the key prerequisite for MAPS’ plan to conduct the clinical trials necessary to develop marijuana into a legal US FDA-approved prescription medicine. In 2004, before our successful lawsuit against DEA, the duo of Massachusetts Senators sent a similar letter to DEA urging the agency to license Prof. Craker. In the coming months, MAPS and our allies will be targeting several key Senators to add their names to Kerry and Kennedy’s letter, building on the momentum of last month’s letter from 45 US Representatives to DEA in support of Prof. Craker’s proposed facility. The DEA has no deadline to decide whether to accept or reject Judge Bittner’s non-binding ruling. As a result, we expect that DEA will continue to use its best weapon against medical marijuana research — inaction.
