In questioning the value of medicinal marijuana, Carly Fiorina said “we don’t understand how it interacts with other drugs.” In fact, there is information about marijuana’s interactions with other medications, although major clinical trials using marijuana have been limited by its legal status.
Fiorina spoke with Fox News’ Sean Hannity, who asked her about the legal status of marijuana in Colorado (it also has been legalized in Washington). She said she believes in states’ rights but that legalizing marijuana is a “bad idea” (at the 30:20 mark):
Fiorina, June 25: I remember when I had cancer, my doctor asked me if I had an interest in medicinal marijuana. I did not, and he said good, because marijuana is a very complex chemical substance now, we don’t understand how it interacts with other drugs, we don’t understand what it does to your body.
The claim regarding drug interactions is not correct: Prescribing information for approved versions of medicinal marijuana does contain drug interaction information, and studies have turned up few problems in terms of interactions with cancer therapies, as well as other types of medication.
