A 2014 Gallup poll reported that over half (51%) of Americans support legalization, with the largest number of supporters in the East and the West.[20] In a Medscape survey conducted earlier last year on marijuana, about 70% of physicians believed that it had real medical benefits, although only 1% had ever personally used marijuana for medicinal purposes.[21] Among physicians who responded to this survey, 59% of those who have ever used marijuana support total legalization, and 20% support it only for medicinal purposes. Even among physicians who have never used marijuana, 51% support some form of legalization (23% total and 28% medicinal). Source
