A 5mg THC edible typically produces effects that last 6 to 8 hours, with the strongest part of the experience hitting around the 3-hour mark. That said, the full timeline from first feeling it to fully returning to baseline varies quite a bit depending on your tolerance, metabolism, and whether you ate beforehand. For someone with little or no cannabis experience, 5mg is considered a standard starting dose, and the effects can stretch closer to 8 to 12 hours. Regular users often find the same dose wears off in about 4 hours.
The Full Timeline of a 5mg Edible
Edibles follow a slow, predictable arc compared to smoking or vaping. Most people start noticing the first effects somewhere between 30 minutes and 2 hours after eating one. The wide range depends on how much food is already in your stomach. Taking an edible on an empty stomach speeds up absorption, while a full meal can delay onset significantly.
Once the effects arrive, they build gradually toward a peak around 3 hours after ingestion. This peak window is when you’ll feel the strongest euphoria, relaxation, or altered perception. After that, the intensity slowly tapers. Most people feel noticeably “back to normal” by the 6- to 8-hour mark, though a subtle background feeling can linger beyond that.
Here’s a rough breakdown of the timeline for a 5mg dose:
- 30 minutes to 2 hours: Onset begins, effects are mild and building
- 2 to 4 hours: Peak intensity, strongest effects
- 4 to 6 hours: Gradual decline, still noticeable
- 6 to 8+ hours: Effects fade to baseline for most people
Why Edibles Last So Much Longer Than Smoking
When you smoke or vape cannabis, THC enters your bloodstream through the lungs and reaches the brain within minutes. It also clears relatively quickly, with most of the high fading within 1 to 3 hours. Edibles take a completely different route.
When you eat THC, it passes through your digestive system and into your liver before reaching your bloodstream. Your liver converts THC into a different active compound that crosses into the brain more effectively and sticks around longer. This converted form is actually more potent than the THC you originally consumed, which is why edible highs often feel stronger and more body-centered than the same dose smoked. The liver processes this compound slowly, releasing it into the bloodstream over hours rather than minutes. That slow, sustained release is the reason a single 5mg edible can keep producing effects for the better part of a day.
What Makes the Duration Shorter or Longer
Several factors push the experience toward the shorter or longer end of the range. Tolerance is the biggest one. If you use cannabis regularly, your body processes THC more efficiently and your brain’s receptors are less sensitive to it. A daily user might barely notice 5mg, while someone trying edibles for the first time could feel strong effects lasting 10 hours or more.
Your metabolism plays a role too. People with faster metabolisms generally process and clear THC more quickly. Body weight and body composition also matter, since THC is fat-soluble and can be stored in fatty tissue, then released gradually. What you’ve eaten recently affects the onset timing, which in turn shifts the entire timeline. An edible taken after a large, fatty meal may take longer to kick in but could also produce a more prolonged effect as the THC is absorbed slowly alongside the food.
The type of edible matters as well. Gummies and baked goods go through full digestion, following the standard timeline. Drinks or tinctures held under the tongue can absorb partially through the mouth lining, leading to a faster onset and sometimes a slightly shorter duration.
Next-Day Effects After a 5mg Dose
Some people report mild residual effects the morning after taking an edible, even at a low dose like 5mg. These can include fatigue, brain fog, dry mouth, dry eyes, or a general feeling of grogginess. This is sometimes called a “weed hangover,” though it’s typically much milder than an alcohol hangover.
Whether you experience next-day effects depends on your individual sensitivity, your tolerance level, and how late in the evening you took the edible. If you take 5mg at 10 p.m. and peak around 1 a.m., trace amounts of THC can still be circulating in your blood when you wake up. At 5mg, this is less common than with higher doses, but it’s worth planning for the first time you try it. Starting earlier in the evening gives your body more time to clear the THC before morning.
How Long THC Stays Detectable After One Edible
The high from a 5mg edible fades within a day, but THC lingers in your body much longer than you can feel it. A standard urine drug test can detect THC for up to a week after a single edible. If you use edibles regularly, that detection window stretches considerably, potentially to 30 days or more for daily users.
Blood and saliva tests have shorter detection windows, generally 24 to 72 hours for occasional use. If you have a drug test coming up, even a single low-dose edible needs a buffer of at least several days to clear, and a week or more to be safe.
