Voters in Pennsylvania are almost unanimous in their support of legalizing marijuana for medical use, so says a recent poll. As a bill to legalize the use of medical marijuana, awaits action in the state Senate, a new poll shows that 85 percent of Pennsylvania voters support the idea. Peter Brown of Quinnipiac University, says support crosses most demographic groups. Governor Tom Corbett has opposed the use of medical marijuana pending further testing. Voters are split down the middle when it comes to legalizing marijuana for recreational use. Men support it more than do women.
