As more and more states across the U.S. legalize marijuana for recreational or medicinal use, it's interesting to note that most Americans don't believe its use will have any impact on the safety of driving in these states.

A new Gallup poll released Saturday found that 30 percent of Americans say legalization will make driving in those states a lot less safe and another 17 percent expect it to make driving a little less safe. However, 50 percent of Americans said it will not make much of a difference.

These results didn't vary too much when broken out by states that already had some form of marijuana legalization versus states with a complete ban.

Across the 23 states and the District of Columbia that have some form of legalization, 49 percent said marijuana legalization will not make much difference in driving safety. In the other states, 52 percent gave the same answer.

Americans 65 and older were the only group that significantly believed legal pot would make driving less safe, according to the poll.
