How Long Do Edibles Last? The Tail, Not the Takeoff

Written by the Rose Mary Jane team. Reviewed by our Cannabis Guides. Last updated 9 October 2026.

Quick answer: Most people report 4 to 8 hours of clear effects from an edible, then a softer tail. A 10 mg serving, the Maine limit for one serving, usually fades inside 4 to 6 hours. A 50 mg dose can run 8 to 12 hours. An edible is cannabis you eat or drink, so your liver sets the pace.

Key takeaways:

• A 10 mg Maine serving commonly gives 4 to 6 hours of clear effects.

• Maine caps a serving at 10 mg THC and a package at 200 mg.

• Blood THC and 11-hydroxy-THC peaked at 1.5 to 2 hours and cleared by 8 hours (Spindle, 2020).

• The 4 hour label warning (18-691 CMR ch. 30) is about onset, not duration.

• Urine detection runs days to weeks, not hours.

Our separate guide to how long edibles take to kick in covers onset, the wait before anything starts, while this page covers how long it lasts. Read that one if you are still waiting on a dose. Read this one if you want to know when it ends.

How long do edibles last at a glance?

Dose is the biggest lever, and the ranges below are what customers tell us at the counter on St John St. They are reports, not lab readings, so hold them loosely.

Maine sets a serving at 10 mg THC and a package at 200 mg THC under Title 28-B section 703. The package cap moved from 100 mg to 200 mg in October 2023. So one legal package can hold twenty servings, which is why the number on the front of the box is not the number you eat.

Our Maine edible dosage chart pairs doses with first time plans. If you are not sure what you bought, our guide to reading a Maine cannabis label shows where the per serving figure sits.

How long does an edible last by dose?

A low dose fades in a few hours and a high dose can own your whole evening. That is the short version, and the research backs the shape of it.

Spindle and colleagues, writing in the Journal of Analytical Toxicology in 2020, gave healthy adults brownies with 10, 25 or 50 mg THC. Whole blood THC and 11-hydroxy-THC peaked 1.5 to 2 hours in, then fell steadily. Both were usually back to baseline within 8 hours.

Felt effects are not the same as blood levels, though. In a companion paper in Drug and Alcohol Dependence, Schlienz, Spindle and colleagues found peak thinking and movement impairment landed roughly 2 to 5 hours after the dose. Both studies stopped measuring at 8 hours, so neither can tell you what hour 10 looks like.

That is the honest limit of the science. The 8 hour window is where the data ends, not where the experience ends.

Why do people still feel it the next morning?

Because the back half of an edible is long and slow, and sleep lands right in the middle of it. A big dose taken at 9pm still has hours to run when you go to bed.

Two things stretch the tail. THC is fat soluble, and Marilyn Huestis, in her 2005 review of cannabinoid pharmacokinetics, describes slow release from fat storage as the rate limiting step in clearing THC. She also points to enterohepatic circulation, where the compound cycles back through the gut and liver instead of leaving in one pass.

In chronic users, that same review cites a reported plasma terminal half life of more than 4.1 days. That figure is about clearance, not about feeling high. It explains why a heavy user can test positive for weeks while feeling completely clear.

The myth worth correcting

The classic "edible hangover" is weaker than the internet claims. A 2023 systematic review led by Danielle McCartney at the University of Sydney reviewed 20 studies on THC effects more than eight hours after use.

Across 345 performance tests, only 12, about 3.5 percent, showed significant next day decline. None of those five source papers used a randomized double blind placebo controlled design, and all were more than 18 years old.

So the next morning fog people describe is usually not measurable impairment. It is more often short sleep, a late heavy dose, dehydration and a day that started badly. Worth knowing before you blame the gummy for your meeting.

What is 11-hydroxy-THC and how long does it stick around?

It is a second active compound your liver makes from THC, and oral doses produce far more of it than smoking does. That is the whole reason edibles feel different and last longer.

Huestis reports that after smoking, plasma 11-hydroxy-THC sits at roughly 10 percent of THC levels. After oral dosing, the two run at similar concentrations. You are effectively dealing with two active compounds instead of one.

In the Spindle brownie study, mean peak 11-hydroxy-THC was 1.4 ng/mL at 10 mg, 4.0 ng/mL at 25 mg and 6.5 ng/mL at 50 mg. Individual readings reached 23 ng/mL at the top dose. Time to peak averaged about 1.9 to 2.2 hours across doses.

The same study found women averaged higher peaks than men at every dose. Nobody can tell you from a label which group you fall into, which is the practical argument for starting at half a serving.

Drinks follow a different curve again. Our notes on how long THC drinks last and how long THC drinks take to kick in cover why a seltzer often runs shorter than a gummy at the same milligrams.

Does food, tolerance or body size make an edible last longer?

These three change the shape of the curve more than they change the clock. That distinction gets lost in most articles about edibles.

• Food: a fatty meal usually slows the start and flattens the peak. The whole thing can feel longer and softer. An empty stomach brings a faster, sharper rise.

• Tolerance: regular users often report a shorter, duller experience at the same dose. It is the single biggest variable we see at the counter.

• Body composition: THC parks in fat tissue, so clearance timing varies between people. It affects detection windows far more than it affects your evening.

• Dose: still the main lever. Doubling the milligrams does more to the length than any of the above.

If your tolerance has climbed to the point where nothing lasts, a reset is the fix. Our guide to taking a tolerance break covers how long people usually need.

How long do edibles stay detectable in a drug test?

Days to weeks, which has nothing to do with how long you feel it. Standard urine tests look for a THC metabolite that lingers well after the effects end.

Goodwin and colleagues followed 60 cannabis users through monitored abstinence for up to 30 days. They split people by starting metabolite level, not by self reported use. Mean time to last positive was 4.3, 9.7 and 15.4 days across the three groups.

One detail trips people up. In 40 percent of participants, the peak metabolite reading came as late as 2.9 days after they stopped. Levels can rise before they fall.

If a test matters to you, assume weeks and not hours. No product on our shelf changes that, and nobody at our counter will tell you otherwise.

Can you make a long edible end sooner?

Mostly no, and anyone selling you a shortcut is selling you nothing. Your liver works at its own speed, and no food, drink or supplement reliably speeds that up.

What actually helps is reducing the load on yourself. Water, a snack, a dim room, a show you have seen before, and a person who knows what you took. Sleep is the fastest route through the back half.

Fresh air and a short walk help some people. Heavy exercise is a poor idea at a high dose, because your heart rate is already up.

Who should skip a high dose edible?

Anyone with somewhere to be in the next eight hours. That is the trade off nobody writes down: an edible buys you a long, even experience in exchange for your whole evening.

Skip the high dose if you are driving later. Maine has no per se THC blood limit, so impaired driving is judged on behavior under 29-A M.R.S. section 2411. An eight hour window is not a safe bet against a six hour plan.

Skip it if you have never taken one. Start at 2.5 mg or 5 mg, wait the full four hours your label warns about, and only then decide. Our guide to a first visit to our shop covers what to ask us before you buy.

Skip it if you take prescription medication, or if you are weighing cannabis against a health question. That is a conversation for a provider who knows your history, not for a label.

Frequently asked questions

How long does a 10 mg edible last?

Most people describe about 4 to 6 hours of clear effects from a 10 mg edible, which is one full serving under Maine rules. The strongest part sits in the first 2 to 3 hours. After that it eases off over a few more. A softer tail can run past the 6 hour mark, especially if you have little tolerance. Plan a free evening, not a free hour.

Why do edibles last longer than smoking?

Eating sends THC through your gut and liver before it reaches your blood. That slows the whole curve down, so the climb, the peak and the fall all stretch out. Smoking sends THC straight to the blood through the lungs, which is why it arrives in minutes and fades faster. The liver route also makes a second active compound, 11-hydroxy-THC, in much larger amounts.

Can an edible really last into the next day?

Many people report a dull, slow morning after a large dose, and that experience is real to them. The measured evidence is thinner. A 2023 systematic review by Danielle McCartney and colleagues at the University of Sydney looked at 20 studies and 345 performance tests. Only 12 tests, about 3.5 percent, showed next day decline. Poor sleep and a late heavy dose explain a lot of what people call a hangover.

How long do edibles stay in your system for a drug test?

Far longer than the effects. Standard urine tests look for a THC metabolite, not the high. Goodwin and colleagues, writing in the Journal of Analytical Toxicology in 2008, followed 60 users during monitored abstinence at a 50 ng/mL cutoff. In the group with the highest starting levels, the mean last positive came at 15.4 days. In the lowest group it was 4.3 days. One edible is usually a shorter window, but no one can promise you a number.

Does eating food make an edible last longer?

Food mostly shifts the shape of the curve rather than the total length. A fatty meal tends to slow the start and smooth the peak, so the whole thing can feel longer and gentler. An empty stomach tends to bring a faster, sharper rise. Neither one adds hours of extra strength. Your tolerance and your dose decide the length far more than your dinner does.

What can I do if an edible is lasting too long?

Mostly you wait it out, and that is the honest answer. Nothing you can buy speeds up liver metabolism. What helps is lowering the input: water, food, a quiet dark room, a familiar show, someone to sit with you. Sleep is the fastest way through the back half. If you feel unwell, call the Northern New England Poison Center on 1-800-222-1222, or 911 in an emergency.
