A new study found 9 out of 10 medical professionals said they were unprepared to prescribe medical cannabis to patients.

The study was published by the Drug and Alcohol Dependence Journal and surveyed 258 medical residents and fellows across the United States.

Eighty-five percent of medical professionals said they hadn’t received any education on medical cannabis and one quarter of deans said their graduates were not equipped to answer questions about its medical uses.

“..There is a fundamental mismatch between state laws involving marijuana and the education physicians-in-training receive at medical schools throughout the country,” said Anastasia Evanoff, third-year medical student and one of the study’s authors.

According to the Association of Medical Colleges database, only nine percent of medical schools teach their students about medical cannabis.
