Weed hangovers, or “stone-overs”, are unfortunately an unpleasant side effect of consuming weed that some users report experiencing. Studies show that a weed hangover is not just an urban myth- if users over-consume, they truly will experience adverse effects the day afterwards.

What are the symptoms?

Studies show that the residual effects of marijuana consumption are what lead to still feeling not-quite-sober the next day. These residual effects include cognitive impairment and delayed response time. During one study, subjects were subjected to a full battery of tests after smoking two joints, and then were subjected to the same tests the next day to see whether the marijuana had any lingering effects.

The tests included heart rate monitoring, subjective rating of the drug’s effects, a circular lights task, serial addition and subtraction, as well as digital recall tests. On the second day, users exhibited no symptoms of an increased heart rate, nor did they report any subjective effects of marijuana. However, users did exhibit some symptoms of a weed hangover on the second day of testing. After consuming marijuana the previous day, test subjects exhibited impaired performance on the arithmetic and digital recall tasks. Thankfully though, the performance decrements were not large as those observed on the first day of testing. The results still suggest that marijuana can impair cognitive performance for up to 24 hours after consumption though, one of the main symptoms that those experiencing weed hangovers report.

A second study describes how the apparent hangover effects of marijuana are indeed different from the acute effects of marijuana consumption. The findings of this earlier study conclude that smoking marijuana can produce residual effects the day after smoking. Many people who claim to experience weed hangovers cite physical symptoms too: headaches, fatigue, congestion and dehydration are all commonly reported.

How can you prevent a weed hangover?

  • Moderate consumption One study suggests that consuming marijuana in lower doses may not cause users to experience any adverse side effects the day after consumption. Consume cannabis in moderation to avoid that next-day stoned-over feeling.


  • Drink plenty of water – Drink plenty of H2O before you plan to consume. This will help combat dehydration, one of the mo commonly experience side effects of cannabis consumption. THC is also fat soluble, which means it is stored in your body’s fat cells. Drinking a lot of water can help to flush the THC out of these cells, helping to get it out of your system faster.


  • Microdosing Microdosing cannabis provides all the great medical benefits of THC to you without the effect of feeling “high”. Choosing to microdose will most certainly help you avoid a weed hangover the next day since you won’t get stoned in the first place.


  • Choose your strain wisely – The quality of cannabis, as well as the strain you choose to consume, can have big effects on your high. Residual nutrients and pesticides/fungicides can sometimes remain in the plant if not flushed properly before curing. These toxins may lead to you feeling a little “off”, so try switching to a different source or strain of buds to see if that stops the stone-overs from occurring.


The smarter you consume, the better you feel, so a little awareness of what you’re smoking and how much can mean the difference between a good and so-so cannabis experience.
