A typical edible high lasts 6 to 8 hours, with the strongest effects hitting around the 3-hour mark after you eat it. That said, the full range is wider than most people expect: someone with higher tolerance might feel effects for only about 4 hours, while someone with lower tolerance can experience a high lasting 8 to 12 hours.
The Full Timeline of an Edible High
Edibles typically take 30 to 60 minutes to kick in, though they can sometimes take up to several hours. This is dramatically slower than smoking or vaping, where effects begin within minutes. The delay catches a lot of people off guard, especially first-timers who assume the edible “didn’t work” and take more before the first dose has even hit.
Once the effects begin, they build gradually and reach peak intensity around 3 hours after ingestion. From there, the high slowly tapers. Most people feel back to baseline somewhere between 6 and 8 hours after eating the edible, though residual grogginess or mild impairment can linger beyond that window. The overall shape of the experience is a slow climb, a plateau, and a long, gradual descent, which feels very different from the sharp peak and quicker fade of inhaled cannabis.
Why Edibles Hit Differently Than Smoking
When you inhale cannabis, THC passes through your lungs directly into your bloodstream and reaches your brain within seconds. When you eat it, THC takes a detour through your digestive system and liver first. Your liver converts THC into a different compound that is equally potent, or possibly more so, than THC itself. This metabolite enters the bloodstream alongside whatever THC hasn’t been converted yet, so you’re effectively absorbing two psychoactive compounds instead of one.
This liver processing is the reason edibles feel stronger and last longer than the same amount of THC inhaled. It’s also why the onset is so much slower: your body has to digest the food, absorb the THC through your gut lining, and then process it through the liver before you feel anything.
What Changes How Long They Last
Several factors push the duration shorter or longer:
- Dose: Higher milligram doses produce longer-lasting effects. A 5 mg edible will wear off faster than a 25 mg one.
- Tolerance: Regular cannabis users, especially those who consume edibles frequently, tend to experience a shorter high (closer to 4 hours). Infrequent users may feel effects for 8 to 12 hours from the same dose.
- Stomach contents: Eating an edible on an empty stomach leads to faster, more intense effects because your body absorbs the THC more quickly. Taking it with a meal, particularly one with some fat in it, slows absorption and produces a more gradual, milder onset.
- Body composition and metabolism: People with faster metabolisms process THC more quickly. Individual variation in liver enzymes also plays a role, since one specific enzyme does the vast majority of THC conversion. How efficiently your body produces that enzyme affects both how strong and how long the experience is.
- Type of edible: Gummies, chocolates, and baked goods all pass through the digestive system and follow the standard timeline. Drinks and tinctures held under the tongue can absorb partially through the mouth lining, which may speed onset slightly.
Starting Dose for New Users
If you haven’t taken edibles before, the standard recommendation is 2.5 mg of THC. This is considered a microdose, enough to produce mild effects without overwhelming someone who doesn’t know their tolerance yet. Even experienced smokers should start at 2.5 mg if they’re new to edibles, because the liver-processed high is a fundamentally different experience than inhaling.
A standard single dose in most regulated markets is 5 to 10 mg. Products are typically divided into portions at these levels, so check the packaging carefully. A chocolate bar labeled as 100 mg, for example, is meant to be broken into 10 or more servings, not eaten whole. The most common mistake with edibles is re-dosing too early. Because the onset can take over an hour, it’s easy to assume nothing is happening and eat more. Waiting at least 2 hours before considering a second dose helps avoid an uncomfortably intense experience.
The Day-After Hangover
Some people feel lingering effects the morning after a strong edible. Commonly reported symptoms include fatigue, brain fog, dry mouth, dry eyes, headaches, and mild nausea. These aren’t universal, and they tend to correlate with higher doses. There’s no set duration for how long these symptoms last, but most people describe them as fading within a few hours of waking up. Staying hydrated and eating before or alongside your edible can reduce the likelihood of next-day grogginess.
How Long Edibles Stay in Your System
The high wearing off doesn’t mean THC has left your body. In a study of infrequent cannabis users, a single 25 mg oral dose produced positive urine results starting around 3 hours after ingestion, and 95% of participants still tested positive at the 8-hour mark, which was the end of the study’s collection window. A lower 10 mg dose was still detectable in 43% of participants at 8 hours.
Those numbers only capture the first several hours. For standard drug screening, a single use can remain detectable in urine for 3 to 5 days, while regular use can extend that window to several weeks or longer. THC is fat-soluble, meaning it gets stored in fatty tissue and released slowly over time. If you’re concerned about drug testing, the duration of the high itself is not a useful guide for how long THC remains in your body.
