Puff, puff, vote.

Four states are voting in November on America's most-smokable plant.

And if voter polls and online bettors are right, the country is about to get even more stoned.

Medical marijuana is on the ballot and favored to pass to Utah and Missouri, two of the more politically conservative states. And adult-use looks likely to pass in North Dakota and Michigan.

Ballots are due by Nov. 6.

Michigan already has medical marijuana, and will vote this cycle on adult-use; one new poll warns the vote might be close; another says "legalize" will win in an avalanche. Bettors on the online betting market PredictIt give it a 96 percent chance.

North Dakota will vote in November on on adult-use pot. An online poll says they'll vote yes. North Dakota would become the most conservative state with totally-legal cannabis.

Missouri will vote on legalizing medical marijuana and using the tax money on veterans. A poll back in 2016 of Missourians found 62 percent support for medical pot.

Utah, probably the soberest, reddest state, will vote on medical marijuana in November. There's a controversy there: the Mormon church says Thou Shalt Not Smoke, but many Utahns don't buy it. A poll found 66 percent support. PredictIt bettors put Mormon marijuana at a 75 percent chance. The legislature seems intent on neutering the legalization if pot passes, making weed hard to actually get.

CONSERVATIVE STATES GETTING WEED

It's a big time for pot. Legalization started in hippie, western states like Colorado, Washington, Oregon and California. Now, most of the blue and purple states have legal marijuana in some form, 31 in all.

Even red states are getting well: there is already medical marijuana in Louisiana, Oklahoma, Montana and West Virginia. Most other states, including super-conservative spots like Mississippi, are preparing initiatives.

MORE LOCAL VOTES

What's more, there are a number of smaller votes on marijuana this November.

Across Ohio, six cities and towns are voting on decriminalizing marijuana. At least six other Ohio cities have already decriminalized the plant. Ohio now allows medical patients to drive to Michigan to buy weed and bring it back.

In Wisconsin, more than a dozen counties will ask voters whether they think marijuana law should change, either allowing medical or adult-use. These votes won't actually change law; it's just a referendum.

The end of cannabis prohibition, which seemed like a long-shot ten years ago, seems on the horizon.
