TL;DR If you took too much, you're very likely fine. Too much cannabis is uncomfortable, not life-threatening for a healthy adult, and the worst of it passes in a few hours. Find a calm, safe spot, sit or lie down, sip water, and wait it out. CBD may help take the edge off. Get medical help if symptoms are severe, if other substances are involved, or if a child or pet ate it.

Take a breath. If you're reading this because you or someone near you took too much, the most important thing to know is that you're going to be okay. It doesn't feel great right now, and it can feel a lot bigger than it is, but it passes. Let's get you comfortable.

First, the reassurance

You cannot fatally overdose on cannabis alone as a healthy adult. There's no recorded case of it, and that's the fact to hold onto while the rest of this settles.

What you're in is an uncomfortable few hours, not an emergency. The peak of an edible sits around two to three hours after it kicked in, and the whole thing eases off over roughly six to eight hours. You are somewhere on that curve right now, moving toward the downslope even if it doesn't feel like it. Nothing you're feeling is doing you lasting harm. It's intense, it's temporary, and it will fade on its own.

What to do right now

The goal for the next couple of hours is simple: get comfortable, feel safe, and let time do the work. Here's what actually helps, roughly in order.

  • Sleep it off if you can. This is the best one by a distance. If you can lie down and drift off, you'll wake up on the other side of it and the worst will be behind you. Even if you don't fully sleep, lying down in the dark does most of the same work.
  • Dim the lights. Bright light feeds the overwhelm. A dark or softly lit room settles the nervous system more than you'd expect.
  • Sip water. Slow, steady water helps with the dry mouth and gives you a small, manageable thing to focus on.
  • Put on something familiar. Calming music, or a TV show or movie you've seen a hundred times, is genuinely one of the best tools here. The familiarity is the point. Nothing new to follow, nothing that can surprise you, just something warm and known playing while you ride it out.
  • Get some fresh air. A few minutes at an open window or on a step outside can reset a spiralling head. Don't go far, just change the air.
  • Breathe slowly. If the anxiety spikes, slow your breathing right down. In for four, out for six. It tells your body the alarm is a false one.

If there's CBD in the house, it may help soften the edge of the THC. Treat it as a maybe, not a fix, and it's no substitute for simply waiting it out.

What you're feeling, and why

The common signs of an edible overshoot are anxiety, a racing or pounding heart, dizziness, nausea, dry mouth, and sometimes paranoia. Unpleasant, all of it, and all of it passes.

The heart-rate one scares people most, so it's worth naming: a fast heartbeat from cannabis feels alarming but is, for a healthy adult, part of the same temporary picture as the rest. The anxiety and the racing heart also feed each other, which is exactly why calming the body down helps the whole thing settle.

As for how you ended up here, it's almost always the same story. Edibles are slow, someone feels nothing at the forty-five-minute mark and takes more, and then two doses land together. The delayed onset does the trick, and your own liver turns up the volume by converting the THC into 11-hydroxy-THC, a more potent form than you'd get from smoking. That's the whole mechanism behind "I only took a bit and it floored me." The onset page covers the timing trap in full.

When to get medical help

Most of the time this rides out at home. But call for help without hesitating in these situations, because they sit outside the "just uncomfortable" picture:

  • A child or a pet ate an edible. This is the serious one. A dose that's mild for an adult can be genuinely dangerous for a small body. Contact your local poison control centre or emergency services right away, and don't wait to see how it develops.
  • Alcohol or other drugs are in the mix. Cannabis alone is one thing. Combined with alcohol, other substances, or certain medications, the risk profile changes, and that's worth a call to a health line or doctor.
  • Symptoms are severe or getting worse. Trouble breathing, chest pain, fainting, being unable to stay conscious, or a level of distress that keeps climbing rather than easing. Trust your gut and call 911.
  • There's an underlying heart or mental-health condition. If the person has a heart problem or a serious mental-health condition, err toward getting medical advice rather than waiting.

Calling for help is never an overreaction. If you're unsure, make the call.

How to not do this again

The prevention is the same three habits every time, and they work. Start low, wait, and store your edibles where they can't be grabbed by accident.

Start at a low dose, 2.5mg if you're not sure, and give it a full two hours before you even think about more. That single rule prevents almost every case of this. How to dose edibles and edibles for beginners lay out the method, and the calculator helps you dose right next time. Then store them properly, sealed, labelled, and well out of reach of kids and pets, because edibles look exactly like candy and that's how accidental ingestions happen. How to store edibles has the details, and everything ties back to the edibles hub.

FAQ

How long does being too high last?

The sharpest part usually eases within a few hours, and the full effects taper off over roughly six to eight hours from when they started. Sleeping through it is the fastest way to skip to the far side.

Does CBD help when you're too high?

It may take some of the edge off the THC for some people. Treat it as something that might help rather than a reliable fix, and don't rely on it in place of simply resting and waiting it out.

Can you overdose on edibles?

Not fatally, as a healthy adult, from cannabis alone. There's no recorded case. You can absolutely take an uncomfortable amount, which is what this page is about, but it isn't life-threatening on its own and it passes.

What should I do if my child ate an edible?

Treat it as urgent. Contact your local poison control centre or emergency services right away. A dose that's mild for an adult can be dangerous for a child, so don't wait to see how they respond.

Is it safe to take 1000mg of an edible?

1000mg is far beyond any legal or recommended dose, and it would be a deeply unpleasant experience, though still not typically life-threatening for a healthy adult taking cannabis alone. Legal packages cap at 10mg for a reason. If you've taken a large amount you'll most likely be okay, but this is exactly why dose matters.
