Scientists Really Don’t Know Why Weed Makes Some People More Productive

Cannabis use is usually thought to impair our ability to pay attention or organize efficiently (and a lot of scientific research backs up that assumption to some extent). But there are also plenty of people who say smoking up helps them focus and get things done.

Addiction psychiatrist Larissa Mooney says she hears this a lot.

"I've heard individuals report that they’ve followed through on tasks or got something accomplished," she told Mashable recently. There are also numerous cannabis companies that market strains and other products as productivity boosters, even though there is no research to back up those claims.

And scientists seem to agree that cannabis itself isn't likely to make you more productive.

"Actually, most of the research on cannabis and motivation shows no effect, or if anything, reduced motivation," said John Salamone, a psychopharmacologist at the University of Connecticut.

Mooney added that marijuana "can impair executive functions, which is to plan and organize." 

But it is possible that cannabis use has an indirect effect on productivity and focus. The plant's ability to induce euphoria, improve mood and other effects could benefit your ability to follow through with things.

"Someone's perception is someone's perception," said Mooney. "During intoxication somebody might have more energy or more euphoria. They may be actually feeling better, at least, temporarily."

This is all speculative though, and there are no solid reasons for why so many people find that marijuana makes them more productive. And we probably won't get to the bottom of that mystery so long as marijuana prohibition remains in effect. By lumping marijuana alongside heroin as a Schedule I drug in the Controlled Substances Act, the federal government has made studying marijuana extremely costly and difficult for researchers like Mooney and Salamone.

So at least one thing is perfectly clear: cannabis prohibition is very unproductive.


The fight to legalize cannabis nationwide should begin by helping veterans get access to medical marijuana, according to Massachusetts Representative - and 2020 presidential candidate - Seth Moulton (D). Right now, vets can't use medical marijuana without the risk of losing their Veteran's Affairs benefits, even if they live in a state that has legalized medicinal cannabis. In fact, so much as mentioning cannabis use to their doctor is enough for a vet to get their benefits stripped.
