Quick Summary
Cannabis edibles work differently than smoking or vaping. When you eat cannabis, your liver transforms THC into a stronger compound called 11-hydroxy-THC. This process takes time but creates longer-lasting effects. Understanding timing helps you avoid taking too much while waiting for effects to start.
Most people feel edibles within 30 to 90 minutes. Peak effects happen around 2 to 4 hours after eating. Effects can last 4 to 12 hours, depending on dose and your body.
Why Edibles Feel Different
The Liver Makes THC Stronger
When you swallow cannabis, it travels through your stomach into your small intestine. From there, THC enters your bloodstream and goes straight to your liver. Your liver contains enzymes (mainly CYP2C9 and CYP3A4) that convert regular THC into 11-hydroxy-THC.
This metabolite is more psychoactive than regular THC. Many researchers believe 11-hydroxy-THC is four times stronger than inhaled THC. It also crosses the blood-brain barrier more easily and stays in your system longer.
This is why edibles can feel more intense than smoking the same amount of THC. The liver transformation creates a more potent compound that affects your brain differently.
First-Pass Metabolism
The process of THC passing through your liver before reaching your brain is called "first-pass metabolism." This is why onset takes longer but effects last longer. Smoking bypasses this process--THC goes directly from lungs to bloodstream to brain in minutes.
Timeline: What to Expect
Onset: 30 to 90 Minutes
Unlike smoking (which works in 5 to 15 minutes), edibles can take 30 to 120 minutes to produce effects. Most people feel something within 30 to 90 minutes, but timing varies based on:
- Stomach contents: Taking edibles on a full stomach delays onset. An empty stomach speeds it up.
- Metabolism speed: Faster metabolisms convert THC to 11-hydroxy-THC more quickly.
- Product type: Sublingual tinctures absorb faster than gummies that must digest.
- Body composition: THC dissolves in fat, so body fat percentage affects distribution.
- Age: Metabolism generally slows with age, which can delay onset.
For adults 50+: Expect the longer end of this range. If you haven't felt anything after 90 minutes, wait at least another hour before considering more.
Peak Effects: 2 to 4 Hours
Peak blood levels of 11-hydroxy-THC typically occur 1 to 2.5 hours after eating. This is when effects feel strongest. Many people report the most intense experience happening 2 to 4 hours after consumption.
The peak can feel sudden if you're not expecting it. You might feel fine at 90 minutes, then notice effects building rapidly between hours 2 and 3.
Duration: 4 to 12 Hours
Once peak effects pass, you'll notice a gradual decline over several hours. Total duration depends on:
- Dose: Higher doses last longer
- Tolerance: Regular users may experience shorter duration
- Metabolism: Slower metabolisms extend effects
- Product formulation: Some products release THC slowly over time
Most people report 6 to 8 hours of noticeable effects. Some feel residual effects (slight grogginess, relaxation) for up to 12 hours. Plan accordingly--you may not want to drive or operate machinery for the full day.
Common Mistake: Taking More Too Soon
The #1 mistake with edibles is "stacking"--taking more before the first dose kicks in. This happens because the delay tricks people into thinking their dose was too small.
Example: Sarah takes a 5mg gummy at 7 PM. By 8:30 PM she feels nothing, so she takes another 5mg. At 9 PM, the first gummy finally kicks in. At 9:30 PM, the second one hits. Now she's experiencing 10mg at once--twice what she wanted.
The fix: Start with 2.5mg to 5mg. Wait a full 2 hours before considering more. Many people feel fine waiting 3 hours to be absolutely sure.
Factors That Affect Your Experience
Individual Metabolism
People with faster metabolic rates produce 11-hydroxy-THC more quickly and efficiently. This leads to faster onset and potentially more intense effects. Slower metabolisms delay onset but may extend duration.
Metabolism naturally slows with age. Adults 50+ often experience longer onset times than younger users.
Food in Your Stomach
Taking edibles with food, especially fatty foods, can slow absorption but may also increase total THC absorption. Fat helps THC dissolve and enter your bloodstream.
Some people prefer taking edibles on an empty stomach for faster onset, then eating a small snack 30 minutes later to aid absorption.
Hydration
Staying hydrated doesn't speed onset, but it can reduce unpleasant side effects like dry mouth and help you feel more comfortable during the experience.
Medications
Some prescription drugs affect the liver enzymes that process THC. Common examples include:
- Certain antibiotics
- Antifungals
- Heart medications
- Antidepressants
If you take prescription medications, talk to your doctor before using edibles. See our guide: Cannabis Drug Interactions for Adults 50+.
Safety Tips for Adults 50+
Start Very Low
Recommended first dose: 2.5mg THC or less. Many older adults find 1mg to 2mg sufficient. You can always take more next time, but you can't undo a dose that's too strong.
Set a Timer
Set a phone alarm for 2 hours after taking your edible. Don't redose until the timer goes off and you've assessed how you feel.
Keep a Journal
Track each experience in a simple notebook:
- Date and time taken
- Dose (mg of THC)
- What you'd eaten beforehand
- Onset time
- Peak time
- Duration
- How you felt

Plan to Stay Home
Never take edibles before driving, using tools, or situations requiring coordination. Plan for at least 8 hours of being at home in a safe, comfortable space.
Have Support Nearby
Let a trusted friend or family member know you're trying cannabis. Make sure they can check on you if needed. Have their phone number handy.
What If You Take Too Much?
If you feel uncomfortably high, remember: no one has ever died from a cannabis overdose. The feeling will pass.
Immediate steps:
- Find a calm, comfortable place to sit or lie down
- Remind yourself this is temporary and will pass in a few hours
- Drink water and have a light snack
- Try black pepper (smell or chew a few peppercorns--it may reduce anxiety)
- Use slow, deep breathing exercises
- Watch something calming or listen to relaxing music
If you feel very uncomfortable, call your doctor or a trusted friend. For detailed guidance, see: What to Do If You Get Too High.
Product Types and Timing Differences
Not all edibles work the same way. Here's how different formats compare:
Gummies and Baked Goods
Onset: 60 to 120 minutes Peak: 2 to 4 hours Duration: 6 to 8 hours These require full digestion before THC enters your bloodstream.
Tinctures (Sublingual)
Onset: 15 to 45 minutes Peak: 1 to 2 hours Duration: 4 to 6 hours Hold under your tongue for 60 to 90 seconds. Some THC absorbs directly through mucous membranes, bypassing liver metabolism. This creates faster onset but shorter duration.
Capsules
Onset: 60 to 120 minutes Peak: 2 to 4 hours Duration: 6 to 10 hours Similar to gummies but may take slightly longer due to capsule dissolving.
Infused Drinks
Onset: 30 to 90 minutes Peak: 1.5 to 3 hours Duration: 4 to 8 hours Liquids move through your stomach faster than solids, potentially speeding onset.

Storing Edibles Safely
Edibles look like regular candy or baked goods. This creates risks for accidental consumption by children, grandchildren, or pets.
Storage rules:
- Keep in original childproof packaging when possible
- Use a locked box or cabinet
- Never leave edibles on counters or in regular candy dishes
- Label clearly with warning stickers
- Check expiration dates--potency decreases over time
For complete storage guidance, see: Cannabis Storage and Safety at Home.
When to Avoid Edibles
Talk to your doctor before trying edibles if you:
- Take blood thinners (warfarin, Eliquis, Xarelto)
- Have heart disease or irregular heartbeat
- Take medications for anxiety or depression
- Have liver disease
- Have a history of psychosis or severe mental illness
- Are pregnant or breastfeeding
Even if these don't apply, always inform your doctor you're considering cannabis. They can check your medication list for interactions.
Travel Considerations
Edibles are popular for travel because they're discreet and don't require smoking. However, do not fly with edibles, even on domestic flights. TSA policy prohibits cannabis products.
If you're traveling by car between legal states, keep products in original packaging and research laws in every state you'll pass through. Never cross international borders with cannabis.
