Voters in Oregon, Alaska and Washington D.C. headed to the polls Tuesday to consider full legalization of marijuana, while Florida voters consider legalizing marijuana for medical uses.

Passage of the marijuana initiatives will continue momentum from recently legalized marijuana in Colorado and Washington and medical marijuana now allowed in more than a dozen states.

Analysts see marijuana support as significant among younger voters and more liberal voters, with older more conservative voters generally opposing the measures. Colorado and Washington exit polls when marijuana was legalized in 2012 showed younger voters came out in greater numbers in those places than elsewhere.

Washington D.C. voters were expected to pass their measure allowing anybody over age 21 to grow up to six marijuana plants and possess up to two ounces of pot.

Following passage, D.C. council members would need to put together a framework for sales and taxation procedures. Council members have already proposed to tax recreational marijuana at 15 percent, and have city alcohol regulators handle the paperwork.

It looks likely, according to analysts, that marijuana will be legalized in Oregon. Although marijuana legalization failed there in 2012, a new campaign focusing on regulatory safeguards seems to have carried the day with pre-election polls showing passage likely. Most recent polling showed legalization favored by around 52 percent of the electorate.

As for Alaska, the race is too close to call. Alaska already allows people to posses up to four ounces of pot legally. However, this measure would allow people to grow their own and creates a fully legal industry. Proponents say marijuana could become a $100 million a year industry with a taxation framework. Polls show the race even.

Florida voters were deciding whether to allow medical marijuana based on doctor recommendations. Under the proposed law, physicians could recommend marijuana in cases where the doctor believed potential health risks were outweighed by the efficacy of medical marijuana.

This measure needs 60 percent approval to pass. Polls have been all over the place, so it's anybody's guess what will happen Tuesday.
