Marijuana Will Probably Be Legal in Most of the Country by 2020


Today, for the first time ever, Gallup reports that a solid majority of Americans are in favor of legalizing marijuana. I’ve drawn my own chart of Gallup’s data because I think their chart doesn’t really give a good sense of just how quickly public opinion on this is changing.

I have a rule of thumb that favorability ratings need to reach about 65 percent before you hit a tipping point where a major social change starts getting codified into law nationwide. There’s nothing magic about this threshold. It’s just a general sense based on previous issues similar to this. And as you can see, public opinion isn’t merely rising on marijuana legalization, it’s accelerating. The rate of increase has gone from about 0.5 points per year in the 90s to 1.5 points in the aughts to 4 points so far in the teens. If this keeps up, we’ll pass the 65 percent threshold by 2016 or so.

There’s a lot of noise in polls like this, and we might see a bit of regression to the mean in the next few years. And Mark Kleiman offers a few other cautionary notes here. So 2016 is hardly a sure thing. But 2020? That seems like a pretty safe bet in most of the country. By coincidence, this was my horseback guess when I wrote about marijuana back in 2009, and it looks like I don’t have any good reason to change my mind on that.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
