A weed high usually lasts about 1 to 4 hours when you smoke or vape, and 6 hours or more with edibles. Some effects, like feeling a bit slow or foggy, can linger well after the main high fades.
How long yours lasts depends on how you consume it, how much you use, how potent it is and your own body. In this guide, we break down the timeline for each method, what makes a high longer or shorter, and what to do if you feel too high.
Weed High Timeline by Consumption Method
The biggest factor in how long a high lasts is how the THC gets into your body. Inhaling sends it through your lungs and into your bloodstream within minutes. Eating it sends it through your digestive system and liver first, which is slower but lasts much longer.
Smoking a Joint, Pipe or Bong
- Kicks in: Within a few minutes
- Peaks: Within about 30 minutes
- Lasts: Around 1 to 4 hours, with some lingering effects after that
A bong high follows the same timeline, but it can feel stronger because bong hits are often larger. Bigger hits usually mean a longer, more intense high.
Vaping Dry Herb
- Kicks in: Within a few minutes
- Peaks: Within about 30 minutes
- Lasts: Around 1 to 4 hours
Vaping follows a similar timeline to smoking, but many people find it feels stronger from the same amount. Research has found that vaping can produce stronger effects than smoking the same amount of cannabis, likely because less THC is lost to burning. A weed vaporizer also lets you control your temperature, which makes it easier to take smaller, more measured sessions.
How Long Does a Dab High Last?
- Kicks in: Almost instantly
- Peaks: Very quickly
- Lasts: Usually 1 to 3 hours, sometimes longer with high-potency concentrates
Concentrates are much stronger than flower, so a dab high can feel more intense than smoking or vaping flower, even though it lasts about as long. With a dab pen, starting with small dabs makes the experience much easier to manage.
How Long Does a High From a Weed Pen or Cart Last?
- Kicks in: Within a few minutes
- Lasts: Around 1 to 4 hours after your last hit
Weed pens and cartridges on a 510 thread battery follow a similar timeline to other inhaled cannabis. They're so easy to use that it's tempting to keep taking puffs, and every hit extends your high. If you hit a pen on and off all day, you may stay high for most of it.
Edibles
- Kicks in: Usually 30 minutes to 2 hours
- Peaks: Around 2 to 4 hours after eating
- Lasts: Often 6 hours or more, with lingering effects that can carry into the next day
Edibles are the slowest to start and the longest to last. The delay is where most people get into trouble. They don't feel anything, take more, and then both doses kick in at once.
What Changes How Long You Stay High
Beyond the method, several things affect how long your high lasts:
- Amount: The more THC you take in, the longer your body takes to process it.
- Potency: Higher-THC flower and concentrates produce stronger, longer highs.
- Tolerance: Regular users often feel shorter, milder effects than occasional users.
- Your body: Metabolism, body weight and genetics all affect how quickly you process THC.
- Food: Eating before an edible can change how quickly it kicks in and how strong it feels.
- Alcohol and other substances: Mixing alcohol with cannabis can intensify effects, make you feel sick and make the experience harder to predict. It's best to avoid combining them.
Why Vaping Makes Your High Easier to Control
If you want a high you can predict and manage, inhaling beats edibles. You feel the effects within minutes, so you can stop when you've had enough instead of waiting an hour or two to find out.
Vaporizers take that control a step further:
- Lower temperatures give you lighter, more flavor-focused sessions.
- Smaller loads let you take just what you need.
- Pre-measured sessions using dosing capsules make it easier to stay consistent.
It's also one of the easiest ways to make your stash last. Learn more in our guide on how to save money on weed.
How to Come Down When You're Too High
Nothing instantly ends a high, but a few things can take the edge off while it wears off:
- Give it time. The high will pass. Remind yourself that the feeling is temporary.
- Rest or sleep. Sleep is one of the best ways to let your body process THC, and you'll usually wake up feeling clearer.
- Drink water and have a snack. This helps with dry mouth and can make you feel more grounded.
- Find a calm space. Dim lights, relaxing music or a quiet room can ease anxiety.
- Try CBD. Some people find CBD helps take the edge off THC, although research is still limited.
- Black pepper or lemon. Some people swear by sniffing black pepper or sipping water with lemon peel. The evidence is mostly anecdotal, but it's harmless to try.
- A cool shower. It can help you feel more alert and refreshed.
These tips can help you feel better, but they won't remove impairment. Don't drive or operate machinery until you're fully back to normal, and keep in mind that impairment can last longer than the high you feel.
Can You Make a High Last Longer?
If you want longer-lasting effects, edibles last the longest of any method. They're a common choice for people who want relief that lasts through the day or night.
With inhaled cannabis, taking another small session as the first one fades will extend your high. Higher-potency products can also last longer, but they bring stronger effects too, so go slowly if you're not used to them.
You might see tips online about eating mangoes to extend a high. There's no good evidence that it works. And while alcohol can intensify a high, mixing the two raises the risk of feeling sick, dizzy or much more impaired than you expected. It's not a combination we recommend.
Tips if You're New to Cannabis
- Start low and go slow. Begin with a small amount, especially with concentrates or edibles.
- Wait before taking more. With edibles, give it at least 2 hours before considering another dose.
- Pick a low-pressure time. Try it on a day off, when you have time to relax.
- Have water and snacks nearby. Dry mouth and the munchies are real.
- Eat something first. A light meal can make the experience more comfortable.
- Avoid alcohol and other substances. They make effects stronger and less predictable.
- Have someone you trust around. It helps if you start to feel anxious.
When to Get Help
Feeling too high is uncomfortable but usually passes on its own. Get medical help right away if someone has chest pain, trouble breathing, severe confusion, a seizure or loses consciousness. In Canada, call 911 in an emergency, or contact your local poison centre for advice.
If you find cannabis is affecting your sleep, memory, mood or daily life, or you're having trouble cutting back, talk to your doctor. People who are pregnant or have a personal or family history of psychosis should also speak with a healthcare provider before using cannabis.
