I just mentioned some issues with the study here:

While those who have not looked into the history of propaganda regarding cannabis ANY time the drug warriors are fighting to keep their budgets to arrest people for possession, those of us who have spent some time reading about this are rightfully skeptical about any study, not just the outcomes, but the basis for funding any studies in and of themselves, since studies that intend to show harm are the ones that get funded, while others do not.
One scientist said the current US policy is like having creationists in control of the science research budget for paleontologists:
Physicist: If All Science Were Run Like Marijuana Research, Creationists Would Control Paleontology
In the face of obstacles to marijuana research from both the Drug Enforcement Administration and the National Institute on Drug Abuse, a theoretical physicist at the California Institute of Technology and one-time MacArthur Fellow is calling out the federal government on its obstruction of science.
During an address before a medical marijuana conference Friday, John H. Schwartz explained how the DEA and NIDA act as a “tag team” to censor science, with NIDA holding a monopoly over legal access to cannabis for research, and the DEA refusing to reconsider the drug’s designation in the Controlled Substances Act as a dangerous substance with no medical value on the basis that sufficient research does not exist. He alleges that the government has blocked research even though it has long been aware of marijuana’s potential to serve many medical benefits including shrink aggressive cancer cells is because it might “send the wrong message to children”
As a physicist, I can assure you that this not how physics works. … We are all expected to act like grownups and accept it gracefully as experiments prove our favorite theories are false. In physics, unlike marijuana policy, we consider the right message to send to be the message that’s true. …
Consider what American science might look like if all research were run like marijuana research is being run now. Suppose the Institute for Creation Science were put in charge of approving paleontology digs and the science of human evolution. Imagine what would happen to the environment if we gave coal and oil companies the power to block any climate research they didn’t like.

Marijuana researchers: Access to research reefer limited by politics

Researchers looking to study the potential health benefits of medical marijuana use are accusing the government of steering its own supply of the drugs toward probes favoring keeping the drug illegal on the federal level, McClatchy Newspapers reported on Wednesday.
“Nobody could explain it — it’s indefensible,” University of Arizona assistant professor Suzanne Sisley told McClatchy. “The only thing we can assume is that it is politics trumping science.”
Sisley said officials at the Health and Human Services Department (HHS) waited three years before approving a university study into whether veterans suffering from post-traumatic stress disorder benefitted more from smoked or vaporized marijuana, despite the Food and Drug Administration signing off on the project.
...The government’s “stash” is located in a 12-acre garden on the campus of the University of Mississippi. University researchers grow about 13 pounds of the drug per year, with much of it distributed for use in projects approved by both HHS and the National Institute on Drug Abuse (NIDA). The institute reported providing more than $30 million in federal funding for 69 studies related to the drug in 2012.
