Most customers who ask us about sleep have already been through melatonin, the tea, the app with the rain sounds, and a podcast about the Roman Empire that was supposed to be boring and turned out to be interesting. THC works differently from all of those, and it works well if you get two things right: how much, and when. Get either one wrong and you get the 7am fog that gives edibles a bad name.
The short version
THC helps most people fall asleep faster, and that's the best-supported part of the science. CBN, the aged form of THC, does little on its own but makes the sleep heavier when paired with THC. CBD is in the gummy to keep the THC calm. Take it one to two hours before bed, start with half a gummy, and give it the occasional night off so it keeps working.
What THC does to sleep
THC is sedating, and it shortens the time it takes to fall asleep. A 1973 trial gave insomniacs 10, 20 or 30mg of THC and found they fell asleep faster and slept longer. Later reviews back that up, with the caveat that evidence for years of nightly use is thin.
It also changes the shape of your sleep. THC cuts down on REM, the stage where you dream, so you dream less. Fewer 3am wake ups from the one where your teeth fall out. Stop after a long stretch of nightly use and your dreams come back vivid for a week or so. That's called REM rebound, and it passes.
The real drawback is tolerance. Use THC every night and your body adjusts, so the same dose does less. Nearly every "it stopped working" story we hear at the counter comes from someone who took a big dose every single night for months. Small doses and the occasional night off keep it working.
Why you wake up groggy
Nearly every groggy morning comes down to one of two things: the dose was too big, or it was taken too late. That same 1973 trial saw it too. The 30mg group reported next-day hangover, the 10mg group didn't.
A gummy takes 30 minutes to two hours to kick in, and it lasts four to eight hours. Take a full strength one at midnight and it's still working at 7am. Nothing went wrong. The gummy was still on the clock.
Take it one to two hours before you actually want to be asleep, and start with half. Half a gummy that works beats a whole one you regret at your desk.
What CBN does
CBN is what THC turns into when it's left in light and air for long enough. Old flower has less THC and more CBN.
On its own, CBN is a weak sleep aid at best. A 2021 review pulled together every published CBN sleep study it could find and concluded there was little evidence that CBN alone is a sedative. The older claim that it is came from studies that had mixed it with THC.
Which is exactly how it's used. CBN alongside THC is what customers report works. The sleep is heavier and the high is duller than with THC alone. That pairing is what nearly every serious sleep gummy is built on.
Why sleep gummies have CBD in them
This is the question we get most. If CBD doesn't get you high or make you sleepy, why put it in a sleep gummy?
The idea is that CBD takes the anxious edge off THC, so you drift off instead of lying there doing your taxes in your head. That's the theory behind every THC plus CBD product. How well proven is it? The studies where CBD clearly calmed a THC high gave people hundreds of milligrams of CBD. A gummy has 5 or 10. What backs it at gummy doses is customer experience, and enough customers report it that makers keep including it.
At much larger doses CBD may help sleep by itself. A 1981 study found 160mg made insomniacs sleep longer, while smaller doses didn't. No gummy is close to 160mg.
The other reason CBD shows up is for anyone who wants no high at all. CBD and CBN gummies with zero THC won't knock you out, but they take the noise down enough to let you fall asleep on your own.
Which one to take
Sorted by how much of a high comes with it, none to plenty.
- No high. Sleep Gummies 3300mg, 30ct. CBD and CBN, no THC, 110mg per gummy. For anyone who wants to feel tired and nothing else.
- Light. Chill Gummies 100mg, 10ct. 10mg THC, indica, no CBN. If you've never had an edible, start here and take half.
- Medium. Sleep Gummies 625mg, 25ct. THC and CBN, indica, 25mg per gummy. Half is a normal dose.
- Strong. Deep Sleep Gummies 1000mg, 40ct. 15mg THC and 10mg CBN per gummy. For anyone who already knows edibles. Half is still a full dose for most.
- Fast. Grape Ape 2 X 1G pre-rolls. Indica. Smoking hits in minutes and fades in two or three hours, which suits you if the trouble is falling asleep and staying asleep is fine.
All of it is in the Sleep collection.
How to dose it
- First night: half a gummy, two hours before bed. If you're new to edibles, half of the 10mg Chill.
- If it didn't do enough: one gummy the next night. Never a second one the same night.
- If it worked: that's your dose.
- Skip a night or two a week when you can. That keeps the dose working.
Common questions
Will THC gummies make me groggy the next day?
Only if the dose is too high or you took it too late. Half a gummy, two hours early, fixes it for most.
CBN or CBD, which is better for sleep?
Neither does much alone at gummy doses. CBN with THC is the combination that works for most. CBD with CBN is the one for anyone who doesn't want a high.
Can I take it every night?
You can, and it will slowly work less. Small doses and the occasional night off keep it effective.
Will I stop dreaming?
You'll dream less while you use it, and more than usual for about a week after you stop. Then it settles.
Does Delta 8 work for sleep?
Regulars say it makes them drowsy, the same way Delta 9 does at higher doses. There's nothing specifically sleep-related about it. What Delta 8 is and how it differs is in Delta 8 vs Delta 9.
