See Frequently Asked Questions about Conducting Research with Cannabis and Hemp.

Marijuana Plant Material

Research grade marijuana products are available in a variety of cannabinoid content specifications as shown below.  While batches contain specific cannabinoid concentrations NIDA may be able to develop bulk marijuana of other cannabinoid concentrations to meet researcher needs.  For information on the availability of marijuana and marijuana products and their specific content please contact the NIDA Drug Supply Program Director, Dr Rik Kline at rkline@nida.nih.gov.

Marijuana cigarettes and bulk marijuana plant material produced under the NIDA DSP are available at no cost to research investigators who have an NIH grant. Marijuana is also available to research investigators who are funded through non-Federal sources on a cost-reimbursement basis. Please see the Note at the end of the tables for more information on costs.

Only bulk marijuana will generally be available for research

Important note regarding cost-reimbursement

The services and material from the NIDA Drug Supply Program are generally free to NIH-sponsored investigators. Some requests may incur a nominal fee depending on study status, funding source, and type of material being requested. Pursuant to HHS policy published May 21, 1999 marijuana for non-Federally funded research is to be provided on a cost-reimbursement basis. NIDA intends to implement the following pricing schedule for collection of fees for marijuana once HHS and NIH develop updated policies and transactional procedures on the specifics regarding cost-reimbursement of research substances for non-Federally supported projects. These policies and procedures may significantly impact the timing, mechanisms, and recipient of any collected fees but will not impact the shipments. An update will be posted once the final Guidance is received.
