Can Weed Cure a Hangover? – VICE

Jack swears by smoking weed to treat a hangover. The first time he tried it was in college as a freshman. He’d been drunk before, and he’d been high before, but after one especially rough night, his world-wise roommate told him weed could blunt his aching hangover.

They couldn’t smoke in the dorm, so they went to his roommate’s car. “Almost immediately I wasn’t focused on feeling bad, just being high, and it felt like my headache and upset stomach were gone,” he says. It also gave him an appetite while recovering. Even today he turns to the green after a night of over-drinking.

Jack’s roommate wasn’t a medical pioneer. Weed has been prescribed—and debated—as a hangover treatment going back generations. Nowadays, plenty of weed smokers testify it’s helped them recover from a hangover, with multiple threads on Reddit filled with users praising the technique. “They don’t call it THC for nothing,” says one, “because it’s The Hangover Cure.” Others are more skeptical, saying marijuana might just exacerbate a hangover headache, even if it’s worked before, and worrying that it might cause anxiety or paranoia, or lead to vomiting.

There’s also a healthy debate over whether it’s better to smoke or take an edible, and theories about the right choice between sativa and indica, depending on your symptoms. Some warned of the dreaded crossfade that happens when you combine weed and alcohol (“If you are still drunk, don’t smoke”), while others wondered why anyone would drink at all when they could be smoking weed instead.

Beyond street-level anecdotes, though, what does scientific research say about smoking dope to treat a hangover? Does it actually work? Is it any better than the myriad other dubious hangover cures out there?

“There’s actually not a lot of study on this,” said Kent Hutchison, a professor of psychology and neuroscience at the University of Colorado in Boulder. He’s studied substance use and cannabis for years, including work on the National Academy of Sciences committee that produced a comprehensive study on the effects of cannabis.

He also said there hasn’t been much study on hangovers in general, which makes the question doubly tricky to answer. But looking at how alcohol leads to a hangover, he said, can help us theorize how smoking weed might help.

Alcohol makes you urinate, which can lead to dehydration; produces an inflammatory response in your immune system; irritates the stomach lining, often provoking nausea or vomiting; lowers your blood sugar, which can make you feel fatigued or jittery; and expands your blood vessels, which can cause headaches.

Many of these problems can be addressed with drinking water and eating food, even when you feel sick. But Hutchison noted that there are three areas in which weed might be particularly helpful. There’s evidence that smoking cannabis can quell nausea and alleviate anxiety. As many smokers can attest, those effects may help you better cope with the day after a night of hard drinking—-it’s just that research hasn’t yet caught up with the folk remedies. Most of what we know about weed and hangovers comes from anecdotal evidence. “It’s true of so many questions around marijuana,” said Hutchison.

Hutchison pointed to another potentially helpful effect of weed: pain relief. Right now, there’s anecdotal evidence to suggest it can help with headache disorders, as well, but not enough clinical study to prove it, according to a 2017 review article in Cannabis and Cannabinoid Research.

There’s some evidence it works best as a headache treatment when you get the combination of THC and CBD, rather than using them separately. Without more study, though, researchers can’t be certain under what circumstances it’s helpful, including for hangovers. “We don’t really know the underlying mechanisms by which marijuana might relieve pain,” Hutchison said. “It’s better to know the real underlying mechanism.”

However cannabis can help with your hangover, it’s important to note that it’s not curing anything so much as letting you live with the consequences of too much drinking while your body recovers. “Marijuana treats the symptoms,” said Elaine M. Burns, naturopathic medical doctor. She’s long advised patients and doctors about using weed therapeutically. The best ways to deal with a hangover, she said, are “A, avoid it begin with, then B, treat the symptoms.”

For A, she offered the usual tips—drink a glass of water between every drink, for example, and don’t overdo it. But let’s say you’ve already botched things and wake up with pounding headache, dry mouth, dizziness, and upset stomach. In that case, Burnes recommended trying some weed alongside more conventional, proven measures. “It’s about rehydrating,” she said, “with water and electrolytes.” Magnesium supplements can be useful, as well as Emergen-C packets, which provide vitamin C and potassium, as an alternative to Gatorade, which contains a lot of sugar. The very best solution to the dehydration problem, she said, is an IV drip and some magnesium.

When it comes time to spark up (or however you get your weed), remember that you’re trying to treat your specific symptoms—choose your strain and method of delivery wisely. Burns noted that THC and CBD both seem to help with pain relief, while CBD helps more with anxiety. Indica strains have more CBD, so take that into account.

About the most we can say with certainty is that you’ll probably feel better while you’re high, recovering from your previous bad decisions, and honestly, it probably won’t hurt. But right now, the science around cannabis is largely unsettled—we’re still in unfamiliar territory, grasping around with anecdotal evidence. If you’re going to use weed to treat a hangover, congratulations, you’re part of the collective experiment.
