California’s lieutenant governor Gavin Newsom says that if Proposition 64 passes — which would legalize recreational marijuana use — it would be a “game changer” across the country.

Never mind Clinton vs. Trump: Millions of Americans can expect to wake up Wednesday and indulge in a soothing palliative to take the edge off the results of a contentious presidential election.

On Tuesday, five states will decide whether to join Colorado, Washington, Oregon, Alaska and Washington, DC, in legalizing marijuana for “adult recreational“ use.

Polling in California, Nevada, Arizona, Massachusetts and Maine shows that, while legalization is slightly favored by voters, the margins are very close.

Taken together, a successful outcome for these ballot measures could add $4.2 billion to legal marijuana retail revenues by 2018, on top of the $6.5 billion projected for the current year, according to Matt Karnes of GreenWave Advisors.

Californians are expected to pass a ballot measure on Election Day legalizing recreational marijuana, and the prospect has cities and counties seeing dollar signs.

Proposition 64 would impose state taxes on the cultivation and sale of marijuana. But it also allows local jurisdictions to add taxes of their own, something many cities and counties said they plan to do.

Economists warn that burdensome taxes and fees on the nascent industry could backfire, fueling the black market and pushing marijuana businesses to decamp for towns where it’s cheaper to operate. For many city and county officials across California, however, the promise of new revenue to fill budget gaps and fund services is too alluring to pass up.

A ban on the sale of marijuana passed in San Jose, California on Tuesday. The actions come as election-day voting on Proposition 64 approaches.

The city’s urgency ordinance “would prohibit commercial use of non-medical marijuana in the city, including commercial cultivating processing, manufacturing, distributing, testing and selling of recreational weed,” according to the Mercury News.

San Jose is only the latest in a run of California cities quickly passing restrictive marijuana laws. Bans are also in place in Berkeley, Palo Alto, Campbell, Foster City, Hayward, Davis, Martinez and more.

A good way to gauge where things stand in the marijuana legalization wars a week before Election Day is to follow the money. And the latest polls, of course.

There are limitations to this approach. Trying to predict the outcome of an election by polling a week or less before the voting ends is a lot like trying to predict how a road trip is going to end by looking out the back window of the car. Ditto with following the money. The financial disclosure reports published, say, 10 days before Election Day don’t tell you how much will be contributed and spent before the polls close.

That said, here’s how things stood about a week ago.

Voters in California and four other states on Tuesday could open a wider door to legalized recreational marijuana, posing substantial regulatory challenges and deepening the tension between state and federal drug laws.

Californians are set to legalize recreational marijuana in Tuesday’s election, two decades after voters approved cannabis for medicinal purposes, according to a new poll.

Proposition 64, which has consistently led in surveys, would allow adults 21 and older to use the drug, possess 1 ounce and grow six plants.

Five other states will vote on legalizing recreational marijuana on Nov. 8 and the impact on Colorado is yet to be seen.

The Colorado green rush is credited with bringing an influx of investment and people to the state. Supporters cite a $2.4 billion economic impact in 2015 but opponents point to concerns about crime and homelessness.

After several incidents downtown this summer, city leaders blamed what they called "urban travelers" -- people drawn to Colorado for legal weed. They even told dispensaries on the 16th Street Mall to avoid selling individual joints.

A homeless man who calls himself "L.A." told Denver 7 he moved here from Louisiana because of marijuana, as he said, "For the best weed ever."

A potential sea change in marijuana legislation is coming, with ballot measures in several states giving voters the opportunity to make it legal for adults.

Arizona, California, Maine, Massachusetts, and Nevada will vote on legalizing recreational marijuana, while Arkansas, Florida, Montana, and North Dakota are considering medical marijuana initiatives.
