How long does a cannabis high last?
It mostly depends on how you use it: a smoke or vape high lasts a couple of hours, while an edible can last most of a day. Here are the typical timelines.
The honest answer is that it mostly depends on how you take it. A smoke or vape high is over in a couple of hours. An edible can run for most of a day. What to expect from each.
Smoking or vaping: fast in, fast out
When you inhale cannabis, it hits quickly and clears quickly. You’ll usually feel it within a few minutes, it peaks somewhere in the first 10 to 40 minutes, and the main effects are mostly gone within about three hours. A little residual fuzziness can linger a bit longer, but the strong part is short. That fast, predictable curve is what makes inhaling the easiest method to control.
Edibles: slow and long
Edibles and drinks are a completely different timeline. Because they go through your stomach and liver first, they can take anywhere from 30 minutes to two hours to kick in, they peak later (often two to four hours in), and the effects can last up to eight hours. A strong dose can leave you feeling it well into the next day.
This slow start is exactly why edibles trip people up. Nothing happens for an hour, so someone takes more, and then two doses arrive at once. The rule with edibles is simple: take a low dose, and wait the full two hours before even thinking about more.
Tinctures under the tongue: the middle path
If you hold a tincture under your tongue rather than swallowing it, it arrives faster than a swallowed edible, usually within 15 to 45 minutes, and lasts around six hours. Swallow it instead and it behaves like a regular edible.
What changes the length
Even within a single method, a few things stretch or shorten a high:
- Dose and potency. More THC means longer and stronger.
- Your tolerance. Regular users often feel it for less time than someone new.
- Your body. Weight, metabolism, and whether you’ve eaten all shift the timing, especially for edibles.
Plan around it
If you need to be clear-headed by a certain time, work backwards. A smoke or vape gives you a couple of hours. An edible can tie up your whole evening, and sometimes the morning after. To see it laid out, the effects timeline tool shows the onset, peak, and wear-off for each method, and the dosage calculator helps you pick a sensible starting amount.
This is general information for a typical adult, not medical or dosing advice. Everyone is different, so start low and give it time.
Frequently asked questions
How long does an edible high last?
Usually four to eight hours, and a strong dose can leave you feeling it into the next day. Edibles also take 30 minutes to two hours to kick in, which is why you should wait the full onset window before taking any more.
How long does a smoking or vaping high last?
You'll usually feel it within minutes, it peaks in the first 10 to 40 minutes, and the main effects are mostly gone within about three hours. A little residual fuzziness can linger a bit longer.
Why do edibles last so much longer than smoking?
Edibles are digested and processed by your liver before the effects hit. That delays the onset and stretches out how long the high lasts, so it arrives late and stays much longer than inhaled cannabis.
How can I make a high wear off faster?
There's no reliable way to speed it up; time is what works. Staying hydrated, eating something, resting, and simply waiting it out all help. If you've taken too much, see our guide on what to do when you green out.
