How long do edibles take to kick in?

Typically 30 to 120 minutes, and occasionally longer on a full stomach. Smoking reaches you in minutes; an edible has to be digested and pass through the liver first. That gap is the single biggest cause of people taking too much — they decide it is not working and eat another.

How long do edibles last?

Usually four to eight hours for the main effect, with a tail that can run considerably longer. Plan the evening around it rather than expecting to be finished in an hour, and never plan to drive.

Why do edibles feel stronger than smoking the same amount?

The liver converts THC into 11-hydroxy-THC, a different compound that crosses into the brain more readily. That conversion barely happens when you smoke. It is why a dose that sounds small on paper can feel substantial, and why comparing an edible to a joint by milligrams alone misleads people.

I took too much. What should I do?

You are not in physical danger, but it can be genuinely unpleasant and it will pass. Find somewhere quiet and familiar, sit or lie down, drink water, and let time do the work. Tell someone you trust what is happening so you are not managing it alone. If you are frightened, or there are other substances or a heart condition involved, call a medical professional.

Can I make a batch weaker after it is baked?

Not chemically, but you can portion it smaller. Cut a tray of brownies into 32 pieces instead of 16 and each piece is half the dose. This is the reason it is worth counting servings honestly before you start rather than after.

Guide

Dosing edibles

Edibles behave differently from everything else, and almost every bad experience comes from the same two mistakes: not knowing the dose, and not waiting long enough. This page is about the second one.

The two-hour rule

Eat one serving. Wait two hours. Then decide. That is the whole of it, and it prevents the overwhelming majority of bad nights.

Edibles take 30 to 120 minutes to come on because they have to be digested first. In that window it is very easy to conclude that nothing is happening and eat another — and then both arrive at once. There is no way to undo that, and no way to speed up the wait.

Why edibles hit differently

When you smoke, THC goes from lung to bloodstream to brain in minutes. When you eat it, it is absorbed through the gut and passes through the liver, which converts a large share of it into 11-hydroxy-THC — a different compound that crosses into the brain more readily.

That is why edibles feel stronger, last longer, and arrive later than the same milligrams smoked. Comparing the two by weight alone will mislead you.

What the tiers mean

These are descriptions of commonly used ranges, not recommendations. Nothing on this site can tell you what dose is right for you, and tolerance varies enormously between people.

Dose	Tier	Generally
1 – 2.5 mg	Microdose	Barely perceptible for most people. Often chosen by someone who wants a very light touch, or who is finding their footing.
2.5 – 5 mg	Low	Noticeable but mild. A common starting point for someone new to edibles.
5 – 10 mg	Standard	The typical size of a commercial edible serving. Clearly felt by most people with some tolerance.
10 – 25 mg	Strong	Substantial. Regular consumers with established tolerance; uncomfortable for many others.
25 mg +	Very strong	A large amount by any measure. Generally only relevant to people with high, well-established tolerance.

If you have no tolerance and no reference point, the bottom of this table is the sensible end to start at. You can always take more tomorrow.

Things that change how it lands

Food. A fatty meal beforehand tends to increase absorption and delay onset. An empty stomach tends to do the opposite. Both change the experience.
Tolerance. Builds quickly with regular use and fades over a break. A dose that suited you last year may not suit you now, in either direction.
Mixing. Alcohol in particular changes things unpredictably. If you are going to combine them, start considerably lower than you would with either alone.
Distribution. A batch that was not mixed thoroughly is not evenly dosed. Two cookies from the same tray can be meaningfully different.
Setting. Somewhere familiar, with people you trust, on an evening with nothing that has to happen. This matters more than most people expect.

If you take too much

It is unpleasant and it is frightening, and it passes. There is no known lethal dose of THC for an adult, and the overwhelming likelihood is that you will be fine in a few hours.

Go somewhere quiet and familiar. Sit or lie down.
Drink water. Eat something plain if you can.
Tell someone you trust what is going on so you are not managing it alone.
Do not drive, and do not take anything else to counteract it.
Let time pass. Sleep if you can.

Call a medical professional if you are frightened and it is not easing, if other substances are involved, if there is a heart condition in play, or if it is a child or a pet. Emergency services deal with this regularly and will not be shocked.

Storing and labeling

Homemade edibles look exactly like food, which is the entire problem. Anything you keep should be labeled with what it is, the date, and the estimated dose per piece, and kept somewhere children and pets cannot reach. Dogs in particular find brownies very quickly and tolerate them very badly.

Work out your own numbers

None of the above helps if you do not know what is in the food. Start with the infusion calculator to find out how strong your butter or oil is, then the dosing calculator to split it across a batch. Every recipe on the site will then scale itself to match.
