There were several big issues voted on in several different states.
Regarding gay marriage, Maine and Maryland are making history as the first state to approve same-sex marriage by popular vote.
Gay marriage is legal in six states and Washington D.C., but those laws were either enacted by lawmakers or through court rulings.
Washington state also voted on legalizing gay marriage but the results have not yet been fully tallied.
On the other hand, Minnesota voted on whether to amend state constitution to ban gay marriage.
Those results are pending as well.
Another big issue was the death penalty, which California was voting to repeal.
With more than half the votes counted, proposition 34 is trailing by about 8 percent, dimming the hopes of death penalty opponents who were trying to abolish it and clear the largest death row in the nation.
Marijuana related measures were on the ballot in six states.
Washington state has voted to legalize marijuana for recreational use.
This allows people over 21 to now purchase up to an ounce of pot from licensed retailers.
Colorado has passed a similar measure.
The first recreational marijuana stores will open up in 2014 and adults will be able to grow up to six plants for personal use.
On the other hand, Oregon rejected a measure to legalize marijuana for all uses.
That specific measure would have allowed adults to grow unlimited amounts for personal use.
Regarding medical marijuana, Massachusetts is now the 18th state to have it allowed.
Voters in Arkansas narrowly rejected it.
If passed, it would have made it the first southern state to allow medicinal marijuana.
Meanwhile, Montana approved restrictions on medical marijuana put in place by the state legislature last year.
