Delta 8 Side Effects: Everything You Need to Know
Delta-8 side effects explained: why edibles last 6-12 hours, what racing heart means, how to verify products, and why 25mg gummies hit harder than expected.
Written by Lorien Strydom
November 5th, 2025
It's midnight and your heart is pounding. That delta-8 gummy you took hours ago hit way harder than expected, and now you're wondering if something is seriously wrong.
You're not alone in this experience, and more importantly, what you're feeling likely isn't dangerous—it's the result of misunderstanding edible timing and THC amounts.
Most delta-8 side effects stem from these two factors rather than the compound itself being inherently problematic.
When you understand that edibles take 60-120 minutes to take effect and last 6-12 hours, and that the 25-50mg gummies sold as single servings are actually high amounts for many people, those intense experiences start to make sense.

What Delta-8 Is and Why Your Experience Varies From Others
Delta-8 THC is a psychoactive cannabinoid that's typically synthesized from hemp-derived CBD in laboratory settings.
Because this synthesis process isn't federally regulated, the quality and consistency of delta-8 products vary significantly between manufacturers.
The "milder than delta-9" marketing creates misconceptions about timing and appropriate THC amounts.
People may assume milder means they can take more or that effects will be shorter-lived, which can lead to taking more than their tolerance allows.
Why Two People Have Completely Different Reactions
Your experience with delta-8 depends on three main factors: the quality and actual content of the product you're using, your individual tolerance level, and whether you're vaping, eating, or using another consumption method.
Someone with regular cannabis use will have a very different experience from someone trying cannabinoids for the first time, even with identical products.
Product quality matters more with delta-8 than with regulated cannabis because manufacturing standards vary.
What the label says and what's actually in the product can be two different things, which explains why your friend's recommendation might hit you completely differently than it hit them.

Common Delta-8 Side Effects and How Long They Actually Last
The most commonly reported side effects of delta-8 include drowsiness, dry mouth, red eyes, and an increased heart rate.
Many people also report feeling on edge, experiencing confusion, or, at higher THC amounts, feeling disconnected from their surroundings.
Duration matters more than most people realize.
Edibles typically produce effects lasting 6-12 hours, while vaping generally lasts 2-4 hours—though individual experiences vary based on THC amount, tolerance, and metabolism.
The Next-Day Effect Nobody Warns You About
Next-day grogginess catches people off guard, especially after late-night edibles. If you take a 25mg gummy at 10 pm, you might still feel foggy when your alarm goes off at 6 am because the effects haven't fully cleared your system.
This isn't unusual or a sign that something went wrong. It's the natural result of taking a substance that lasts 6-12 hours and expecting to feel baseline after only 8 hours of sleep.
Why Edibles Hit Differently and the 25mg Gummy Trap
Edibles take 60-120 minutes to produce noticeable effects because they have to move through your digestive system and get processed by your liver before entering your bloodstream.
This delay creates the most common delta-8 mistake: taking another serving because "nothing happened."
Here's what actually happens when you fall into this trap. You take 25mg at 8 pm and feel nothing by 9 pm, so you take another 25mg.
Both servings are now working through your system, and around 10-11 pm, you experience the combined effects of 50mg, which can feel more intense than expected and last well into the next morning.

What "One Serving" Actually Means
Those 25-50mg gummies sold as single servings are actually high THC amounts for many users, especially those new to cannabinoids or with lower tolerance.
The packaging might suggest eating the whole gummy, but many experienced users report that 10-25mg is a more typical range for a comfortable edible experience.
We offer a range of THC gummies with clear THC content labeling so you can find the strength that works for your tolerance level.
Starting with a lower THC amount and waiting the full two hours gives you much more control over your experience.
Was It Too Much THC or a Sketchy Product
Unregulated synthesis creates two problems: contamination from the chemical conversion process and labels that don't match the actual contents of the product.
These issues explain why two seemingly identical gummies can produce wildly different experiences.
Learning to verify product quality protects you from both problems. A Certificate of Analysis (COA) is a lab report showing what's actually in a product, and every reputable manufacturer provides them.
How to Actually Verify a COA
Match the batch number on your product package to the batch number on the COA—they should be identical.
Check that the tested THC amount per piece matches what the label claims. Look for testing that includes residual solvents and heavy metals, not just cannabinoid content.
Red flags include generic COAs without batch numbers, missing contaminant testing, or huge variances between labeled THC amounts and tested results.
When a COA shows 15mg but the label claims 25mg, trust the lab test.
Why We're Transparent About Testing
At Mood, we provide batch-specific COAs for our delta-8 gummies and other delta-8 products because we understand this verification matters to you.
You shouldn't have to guess whether you're getting what the package promises.
When Your Heart Races or You Feel Uneasy
Increased heart rate and feelings of unease are commonly reported experiences with edibles.
If you're experiencing these sensations, know that they typically resolve within 4-6 hours as the effects naturally wear off.
These reactions are your body's response to THC.
They're similar to drinking too much coffee and feeling jittery—uncomfortable but temporary.
When to Seek Medical Attention
Seek immediate medical care if you experience severe symptoms including chest discomfort, significant difficulty breathing, or loss of consciousness.
These situations require professional evaluation.
For typical symptoms like racing heart and feeling on edge, finding a comfortable place to rest, staying hydrated, and remembering that the effects are temporary can help.
Time is the main factor—your body will process the THC and you'll return to baseline.
Next-Day Grogginess and Planning Your Timing Better
That morning fog after a late-night edible happens because the effects have a long tail that extends past when you fall asleep.
If you took an edible at 11pm and it lasts 8-10 hours, you're waking up while THC is still in your system.
Better timing means earlier consumption when you want to avoid morning grogginess.
Taking your edible at 7pm instead of 10pm gives the effects time to mostly clear before morning, even with the 6-12 hour duration.
Lower THC Amounts Create Shorter Effects
The intensity and duration both scale with THC amount. A 10mg edible generally produces a shorter, lighter experience than a 50mg edible, which means less chance of waking up foggy.
Our hemp-derived edibles selection includes options at different strengths so you can find what works for your schedule and tolerance.
This isn't about avoiding cannabinoids—it's about using them in ways that fit your life.
Delta-8 vs Delta-9 and Other Cannabinoids You'll Encounter
Delta-8 is typically less potent per milligram than delta-9 THC, meaning you might need a higher delta-8 amount to achieve similar effects. Delta-10 is often reported as even lighter than delta-8, while HHC tends to land closer to delta-9 in terms of intensity.
These comparisons matter for understanding what you're getting, but don't confuse "milder" with "shorter duration" or "can't overconsume."
A milder compound taken in high amounts still produces intense effects, and the timing considerations remain the same across all these cannabinoids.
Why "Milder" Doesn't Mean Lower Effects
The "milder" framing has created confusion because people assume they can be less careful with delta-8.
The reality is that respecting timing, starting with lower THC amounts, and verifying product quality matters just as much with delta-8 as with any other cannabinoid.
Whether you're exploring THCa flower or delta-8 products, the same principles apply: understand what you're taking, start conservatively, and give it time to work before taking more.
Mixing Delta-8 With Medications and Health Conditions
Delta-8 is processed by your liver through the same pathways that metabolize many medications. This means delta-8 could potentially affect how your body processes other substances you're taking, though research on specific interactions remains limited.
Common medication categories that raise questions include SSRIs and other mood-related medications, blood pressure medications including beta blockers, and sleep aids.
We cannot advise on whether delta-8 is appropriate for you if you take any medications.
Why You Need Professional Guidance
Consult with your healthcare provider before using delta-8 if you take any medications or have existing health conditions. They can evaluate your specific situation, medication regimen, and health history in ways we cannot.
This isn't us being overly cautious—it's us being honest about the limits of what we can tell you.
Product information and general education are very different from personalized medical guidance, and only a licensed professional can provide the latter.
What Happens When You Stop Using Delta-8
Regular delta-8 users who stop sometimes report experiences similar to taking a break from regular cannabis use.
These might include irritability, sleep disruption, or cravings that typically improve over days to weeks.
Experiences vary widely between individuals. Some people report no noticeable effects when stopping, while others describe several days of adjustment before feeling back to baseline.
The Drug Testing Reality
Standard drug tests cannot distinguish between delta-8 and delta-9 THC.
If you're subject to drug testing for employment or other reasons, using delta-9 gummies or delta-8 products will likely trigger a positive result on a standard THC test.
This applies whether you're using delta-9 gummies or delta-8 products.
The testing technology looks for THC metabolites that both compounds produce, making them indistinguishable in standard screening.
The Legal Gray Area That Explains Product Inconsistency
The 2018 Farm Bill created the situation where delta-8 exists: it's derived from legal hemp but produces psychoactive effects similar to cannabis.
This gray area means products aren't subject to the same testing, labeling, and quality standards as either FDA-approved products or state-regulated cannabis.
This regulatory gap directly explains the product inconsistency that drives people to search for side effects information. When there's no oversight requiring accurate labeling or quality standards, verification becomes your responsibility rather than being handled by regulators.
Your Next Delta-8 Experience Can Be Predictable
Understanding timing transforms delta-8 from a gamble into a predictable experience.
When you know edibles take 60-120 minutes to work and last 6-12 hours, you can plan consumption times that don't interfere with sleep or next-day responsibilities.
Verifying products through batch-matched COAs and choosing reputable manufacturers gives you confidence that the label matches what's inside.
And respecting THC amounts by starting lower and waiting longer between servings prevents the stacking effect that causes most intense experiences.
Knowledge Replaces Guesswork
You don't need to avoid delta-8 to avoid bad experiences.
You need to understand how it works, verify what you're getting, and use it in amounts and at times that fit your tolerance and schedule.
We're here to provide that transparency through clear labeling, accessible testing results, and products designed for different experience levels.
