NEW YORK ( MainStreet) — The contract for growing marijuana for the U.S. government is up for renewal, and it will be closely watched as the government likes to protect this monopoly. For 30 years, the University of Mississippi has been the sole provider of cannabis for government sanctioned marijuana research. That could change.

The contract comes up for renewal every five years and on May 29, the government posted a new request for proposals . Previously the contract amounts weren't significant, but with the increasing demand for study material, the National Institute of Drug Abuse, or NIDA, increased the quota to 46 pounds. NIDA decides who gets government grown marijuana for research.

The Drug Enforcement Agency has come under fire for creating the monopoly under NIDA and awarding the contract to only one supplier. The group cites the UN's Single Convention on Narcotic Drugs from 1961 as the reason why only one supplier is approved. The convention requires each nation to designate a single official source of marijuana. However, paragraph 2(b) of Article 29 of the Protocol states that a country " ..ensure that the manufacture of drugs, their salts and preparations is restricted to as small a number of establishments and premises as practicable." That language seems to permit a few suppliers, not just one necessarily.

There are over 700 registered growers for medicinal marijuana in the state of Colorado alone that could bid on this contract. Not to mention public companies like Cannabis Sciences that might want to become a major marijuana supplier to the government. You would think that they would jump at the chance to be the nation's supplier, but that isn't the case.

Rick Doblin, founder & executive director of the Multidisciplinary Association for Psychedelic Studies or MAPS said, "No one would bid on this contract because first you'd have to give all of your product to NIDA, but then you also test seized marijuana that is used to arrest people. Most marijuana growers don't want to be a part of a group that wants to throw people in jail."

Doblin went on to explain that in his opinion the NIDA monopoly exists to keep medical marijuana from being legalized. For example, if a researcher uses NIDA pot for a cancer study and then has good results and the FDA approves it, the researcher is unable to sell that product to the cancer patient. It is only grown for research not for resale. Under those circumstances, a nightmare scenario emerges: being able to tell a cancer patient you have a remedy, but you're unable to give it to them. Doblin's group, along with Dr. Lyle Craker, a respected professor at the University of Massachusetts has fought long and hard for decades to break the monopoly.
