New York Dr says marijuana should be taken off controlled substance list

Dr. Mary Jeanne Kreek said that Congress should remove marijuana from the Controlled Substances Act list, arguing that such a move would help facilitate more medical research.

Kreek, a senior attending physician Rockefeller University, said her lab has struggled to get permission to study two key active ingredients derived from the cannabis plant: tetrahydrocannabinol (THC) and cannabidiol (CBD).
