What cancer patients actually know regarding medical cannabis? A cross-sectional survey with a critical analysis of the current attitudes

In Italy medical cannabis is a prescription drug since 1998. Even though it could not be considered a therapy as such, it is indicated as a symptomatic treatment also in cancer patients, to cure iatrogenic nausea/vomiting and chronic pain. We conducted a knowledge survey about medical cannabis among cancer patients referred to two outpatient cancer care centers and a home care service. Our survey shows that most of Italian cancer patients know medical cannabis and a third of them have considered using cannabis to treat one (or more) of their own health problems. In the same time, they are poorly informed and do not tend to ask for information about medical cannabis to healthcare professionals.
