How Long Does a Cannabis High Last?
A cannabis high can last anywhere from 2 to 10 hours, depending on a range of factors.
- how much you consume
- how much tetrahydrocannabinol (THC) it contains
- your body weight and body fat percentage
- your metabolism
- whether or not you’ve eaten
- your tolerance
Cannabis contains more than 113 chemical compounds called cannabinoids. Delta-9 tetrahydrocannabinol (THC) is one of those cannabinoids, and it’s the ingredient responsible for making you feel high.
Here’s a closer look at the timeline of a delta-9 THC high and tips for cutting things short.
How quickly you feel the effects mostly depends on your method of use:
- Smoking or vaping. You can begin to feel the effects of cannabis within 2 to 10 minutes. It kicks in quickly because it enters your bloodstream via your lungs within minutes of inhaling it.
- Eating. Your digestive system metabolizes pot when you eat it, which can take a while. Edibles usually kick in within 30 to 60 minutes, but can sometimes take as long as 2 hours.
- Dabbing. With this method, a highly concentrated form of marijuana is smoked through a special pipe. Dabs have a higher THC content than other forms of cannabis, so the high kicks in almost instantly.
How long the effects last can vary greatly depending on the dose and potency. The more you use and the higher the THC content, the longer the effects will stick around.
How you consume cannabis also affects when the effects peak and how long they last.
Here’s a breakdown, according to Drugs and Me, a site by the Mental Health Education Foundation:
- Smoking or vaping. The effects peak around 10 minutes after consumption and typically last 1 to 3 hours, though they can linger for up to 8 hours.
- Eating. The effects of edibles usually peak around 2 hours after consumption and can last up to 24 hours.
- Dabbing. Similar to smoking, the effects of dabbing usually last 1 to 3 hours. If using a high THC concentrate, you could feel the effects for an entire day.
Cannabis hits everyone differently, so while your high may only last for a couple of hours, you could potentially feel the comedown or aftereffects for several hours or through the next day. It’s best to go low and slow if you’re new to cannabis.
If you need to cut things short, there are a few things you can try.
Keep in mind that these tips are designed to reduce the effects, not eliminate them altogether. That means you’ll likely still experience lingering effects, including a reduced reaction time, so you’ll still want to avoid driving.
Here are a few pointers based on anecdotal evidence and some research:
- Take a nap. Sleeping can help you relax if your high has you feeling anxious or paranoid. It also gives your body time to process and eliminate the cannabis. You’ll likely wake up feeling refreshed and more alert after a few winks.
- Try some black pepper. There’s some evidence that caryophyllene, a compound in peppercorn, increases the sedative effects of THC, which could calm you. Just take a container of black pepper and have a sniff without inhaling it. Chewing on a couple of whole peppercorns also works.
- Eat some pine nuts. Some research shows that pinene, a compound in pine nuts, has a calming effect and improves clarity. Skip this method if you have a tree nut allergy, though.
- Try some CBD. Yep, it may sound counterintuitive, but CBD may counteract the effects of THC. Like THC, cannabidiol (CBD) is a cannabinoid. The difference is the receptors in your brain that they interact with. THC causes the high you get from cannabis, but CBD has a calming effect that may help dull your high.
- Have some lemon peel. Lemons, especially the peel, contain compounds that have a calming effect. In theory, ingesting some lemon peel could counteract some of the psychoactive effects of THC and help you come down. Try steeping some in hot water for a few minutes, then remove them and take some sips.
If you’re looking for a longer-lasting high, consider sticking with edibles. They take longer to kick in, but the effects will hang around longer, which can be a big help if you’re using cannabis for medical purposes.
You could also re-dose or try a higher THC strain for a longer high, but know that you’ll also have to deal with more intense effects. For a seasoned consumer, this is probably not a big deal, but a newbie may find the effects of a bigger dose to be a bit much.
There are some anecdotal methods for extending your high on the Internet, like eating mango, but there’s no evidence to back any of these.
Some websites recommend drinking alcohol with cannabis to extend your high, but it isn’t the best idea.
Drinking before using cannabis — even just one drink — can heighten the effects of THC. This combo can cause some folks to “green out” and experience some pretty unpleasant symptoms, including:
- increased impairment
This combo doesn’t work great in the other direction, either. Using cannabis before drinking can minimize the effects of alcohol, meaning you’ll feel less drunk than you are. This makes it easy to get overly intoxicated.
Plus, using cannabis and alcohol together may increase your risk of dependence on one or both substances.

PSA: Don’t Smoke Those Stems
These are crazy times, so it’s not that weird that you’re looking at your bowl of weed stems and contemplating smoking them. Waste not, want not, right?
As nice as it is to reduce waste and be resourceful, smoking stems isn’t the way to go.
If stems are all you have left, then you’ve already smoked the good stuff.
Stems contain almost no THC. What little may be in there doesn’t even come close to being enough to produce a high.
The negligible amount of THC in stems isn’t worth the unpleasant effects and risk to your lungs that come with smoking.
Inhaling smoke harms your lungs. It doesn’t matter if it’s bud, seed, tobacco, or burning wood. Toxins and carcinogens (cancer-causing agents) are released from the combustion of materials, even stems. This damages your lungs and increases your risk for cancer and heart and lung diseases.
Smoke effects aside, smoking stems can cause:
- a raging headache
- a sore throat
It’ll also taste like you’re smoking wood chips.
Some people on Reddit and other forums who admit to having smoked weed stems also reported uncomfortable gastrointestinal symptoms, like nausea and abdominal pain.
Nope. You shouldn’t smoke those either.
Marijuana seeds aren’t going to get you high no matter how many you crush and smoke. There’s just not enough THC in the seeds to produce any effects.
Lighting them up will create a lot of snap, crackle, and pop. The acrid smoke will irritate your throat and damage your lungs like other smoke. But that’s about it.
Stems and seeds aren’t worth smoking, but that doesn’t mean they’re entirely useless. You may be able to use lingering stems and seeds. Exactly what you can do with them depends on how many you have.
If you just have a few seeds kicking around, you could plant them and try growing your own stash (if you live in an area where this is permitted, of course).
Have an abundance of stems and seeds to play with? Consider eating it.
Here are some ways to make it appetizing.
Brew some stem tea
Before getting your brew on, you’ll want to bake the stems on a baking sheet in the oven for around 45 minutes at 225°F (107°C). When done, let the stems cool, and then grind them up.
Put your ground stems in a tea diffuser and let them steep in boiling water for 10 to 15 minutes. If you don’t have a diffuser, you can steep your ground stems in a pot of boiling water and then place a coffee filter over your mug and pour so it strains your brew.
Make stem butter
Who doesn’t like butter?
Just like when making tea from weed stems, you’ll want to bake your stems in the oven at 225°F (107°C) for 45 minutes and let them cool before grinding.
Place some butter in a pan and melt over low heat. Once the butter’s completely melted, add the ground stems and let simmer for around 30 minutes, stirring often.
To strain it, cheesecloth works best. Just secure the cheesecloth over a glass jar with a rubber band, and slowly pour the butter over the cloth. Let the butter cool and — voilà — stem butter!
It might be tempting to smoke all those stems that are gathering dust in your jar, but you may want to think twice before lighting up.
