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.Find out how long it takes for weed’s effects to kick in and how long they last. We’ve also got tips for cutting things short or extending them.
How to Tell If Cannabis Is Past Its Prime
Weed doesn’t go bad the way a jar of mayo or some other food product might, but it can definitely be “off” or even moldy.
Old weed likely won’t lead to any serious health issues if you don’t have any underlying conditions.
It can, however, have a noticeable drop in potency, which can be a big deal if you’re using it for medical purposes. Older weed can also undergo changes in taste and texture.
When stored properly (more on this later), dried cannabis keeps for 6 months to 1 year. Over time, it begins to lose its aroma and potency.
According to some older research, weed loses roughly 16 percent of its THC after 1 year, and it just keeps dropping from there:
- 26 percent THC lost after 2 years
- 34 percent THC lost after 3 years
- 41 percent THC lost after 4 years
It’s mostly in the smell. Weed that’s past its prime will smell different or lose its aroma entirely. Some weed might even smell and taste harsh when it’s been sitting too long.
Its appearance can also give you a clue as to whether or not it’s old. Fresh weed shouldn’t crumble or feel spongy when you break it off. If it does, it’s old and either too dry or too moist.
Consuming it shouldn’t harm you, but be prepared for changes in texture and potency. The exception is weed that’s grown mold, which could potentially make you sick.
Mold is often hard to see unless you look very closely. It typically looks like white powdery or fuzzy spots, some of which can be pretty small.
Moldy weed usually smells musty, kind of like hay. It also tends to have a bit of an “off” taste.
Even if your weed isn’t super old, it’s best to do a mold inspection. A study by researchers from University of California, Davis found bacteria and mold on 20 cannabis samples bought from dispensaries and pot growers in Northern California.
Mold on weed isn’t likely to cause major health problems, but it can lead to nausea, vomiting, and coughing.
In people with weakened immune systems, inhaling smoke or vapors from weed containing bacteria or fungi could cause serious illness or even death.
If it looks or smells off, then you’re better off tossing it, even if you just bought it.
Light, humidity, temperature, and oxygen can all mess with cannabis and affect its aroma, taste, and potency potential.
Here’s what to consider when storing weed to help keep it fresh and maintain its quality for as long as possible.
Choose the right container
Ditch plastic baggies and containers. Plastic holds static that can affect delicate trichomes — the tiny, crystal-like hairs on flowers that produce cannabinoids and terpenes — and mess with potency.
And forget those funny little tins, too, because they let in too much oxygen.
Glass jars with an airtight seal, like mason jars, are the way to go. They don’t have any static charge and limit oxygen exposure. Plus, they’re inexpensive and easy to find.
Most dispensaries also sell containers designed to keep weed fresh for as long as possible.
If you have kids or pets in your household, invest in a child- and pet-proof container.
Watch the humidity
Weed is best kept at a relative humidity of 59 to 63 percent. Any higher and you run the risk of trapping moisture, which can lead to the growth of mold. Anything lower can cause your weed to dry out.
To help you preserve your stash, you can add humidity packs to your containers if you really want to get fancy. You can also go the extra mile and store your weed in a humidor made specifically for cannabis.
Keep it cool, dark, and dry
Keeping weed in a cool and dry spot away from sunlight is as important as the container you use, if not more so.
Direct sunlight can cause cannabis to break down, and too much heat can hold moisture and lead to mold.
Keeping it somewhere too chilly, on the other hand, could dry it out and lose those precious trichomes, which is why the fridge and freezer aren’t recommended.
Aim to store cannabis in a dark place, like a closet or cabinet, with a temperature below 77°F (25°C).Weed doesn't go bad in the way perishable food does, but it can definitely degrade over time. Here's what to look for. ]]>
