Someone could ask him why the Federal Government holds a patent on the use of cannabinoids- the main ingredient in cannabis. But since that hasn't happened since the patent was granted in 2003 I don't expect it to happen now.
US PATENT #6630507 October 7, 2003
Assignee: The United States of America as represented by the Department of Health and Human Services (Washington, DC)
Cannabinoids as antioxidants and neuroprotectants
Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia...

There's this from the National Institutes of Health
Have any preclinical (laboratory or animal) studies been conducted using Cannabis or cannabinoids?
Preclinical studies of cannabinoids have investigated the following activities:
Antitumor activity
Studies in mice and rats have shown that cannabinoids may inhibit tumor growth by causing cell death, blocking cell growth, and blocking the development of blood vessels needed by tumors to grow. Laboratory and animal studies have shown that cannabinoids may be able to kill cancer cells while protecting normal cells.
A study in mice showed that cannabinoids may protect against inflammation of the colon and may have potential in reducing the risk of colon cancer, and possibly in its treatment.
A laboratory study of delta-9-THC in hepatocellular carcinoma (liver cancer) cells showed that it damaged or killed the cancer cells. The same study of delta-9-THC in mouse models of liver cancer showed that it had antitumor effects. Delta-9-THC has been shown to cause these effects by acting on molecules that may also be found in non-small cell lung cancer cells and breast cancer cells...more

It isn't exactly a secret
President Obama Gives Full Support of Medical Marijuana
Weed 3 will air this Sunday at 9PM EST on CNN with an anticipated special guest attracting more attention to the series than ever before. Sources are reporting President Obama will be giving his full support of medical marijuana, as well as discussing his views on drug abuse and incarceration.
The Daily Caller’s Jonah Bennett reports that an email obtained by The Daily Caller News Foundation reveals the details of Dr. Sanjay Gupta’s interview with President Obama in the special, “Weed 3.”
The President boldly discusses medical marijuana and the recent bipartisan bill, the CARERS Act, which proposes the rescheduling of marijuana from a schedule 1 to a schedule 2 drug. On the subject of the CARERS Act, President Obama says, “You know, I think I’d have to take a look at the details, but I’m on record as saying that not only do I think carefully prescribed medical use of marijuana may in fact be appropriate and we should follow the science as opposed to ideology on this issue, but I’m also on record as saying that the more we treat some of these issues related to drug abuse from a public health model and not just from an incarceration model, the better off we’re going to be.”

Earlier in Jamaica:
President Obama crushes marijuana supporters with these 15 words
Motley Fool April 19, 2015
...But, in spite of marijuana's incredible momentum -- which has led 23 states (plus Washington, D.C.) to approve it for medical use, and four states (plus Washington, D.C.) to legalize it for recreational use -- President Obama had some choice words earlier this month while speaking in Jamaica about the future of the marijuana industry in the United States.
When asked about where the U.S. stands on the legalization of marijuana, Obama uttered 15 words sure to send shivers down the spines of marijuana supporters:
I do not foresee, any time soon, Congress changing the law at a national basis.
President Obama's expanded commentary went as follows:
Right now, that is not federal policy, and I do not foresee, any time soon, Congress changing the law at a national basis. But I do think that if there are states that show that they are not suddenly a magnet for additional crime, that they have a strong enough public health infrastructure to push against the potential for increased addiction, then it's conceivable that it will spur on a national debate. But that is going to be some time off...
