Does CBD Make You High? Understanding the 0.3% THC Rule
CBD won't make you high, but products with 0.3% THC can contain 15mg in a 5g gummy. Learn to read COAs, choose the right spectrum, and avoid surprises.

CBD itself won't make you high.
But here's what the CBD industry doesn't always explain clearly: products labeled as CBD can contain enough THC to create noticeable effects, especially at higher amounts or with certain product types.
The confusion isn't your fault.
The 0.3% THC limit sounds reassuring until you understand it's a percentage by weight, not a feelings guarantee.
We're going to walk through the practical framework you need: understanding what the 0.3% rule actually means in real-world terms.
We'll aso explain how to read a Certificate of Analysis to verify THC content, and how to choose products based on your THC sensitivity.
By the end, you'll know exactly which products will keep you clear-headed and how to avoid surprises.

The Straight Answer About CBD and Getting High
CBD is non-intoxicating because it doesn't bind to CB1 receptors the way THC does. This is why it won't create a high on its own.
Here's where confusion creeps in: CBD is technically "psychoactive" because it affects your mood and consciousness. But psychoactive doesn't mean intoxicating.
Many people experience subtle effects from CBD like relaxation or calm. Some mistake these feelings for being high, but they're fundamentally different from THC's intoxicating effects.
The real story gets more complex when we look at actual CBD products.
Many contain other cannabinoids beyond pure CBD, and that's where the possibility of feeling high enters the picture.
Understanding the difference between CBD and THC is the foundation for making informed choices about which products match your goals.
Why 0.3% THC Doesn't Mean What You Think
The 0.3% THC limit is a percentage by dry weight. This distinction matters more than most people realize.
Let's do the math on a 5-gram gummy at 0.3% THC: that's 15mg of THC. THC-sensitive users will absolutely feel 15mg.
This explains why some people report feeling buzzed from supposedly non-intoxicating products. The percentage sounds tiny, but it can add up by product weight.
Product types break down into three categories based on THC content.
Full-spectrum CBD contains up to 0.3% THC along with other cannabinoids.
Broad-spectrum CBD typically has non-detectable THC levels.
This doesn't mean zero THC - it means below the lab's detection limit.
CBD isolate contains only CBD with no other cannabinoids present. This is the lowest-risk option for avoiding any THC exposure.
The common confusion around broad-spectrum deserves special attention.
Many people assume "broad-spectrum" means "no THC," but it actually means THC levels are below what the lab can reliably measure.
If you're highly sensitive to THC or concerned about drug testing, understanding these distinctions becomes critical for product selection.
Reading a COA Like You Know What You're Doing
A Certificate of Analysis (COA) is your verification tool. Every reputable product should have one available for the specific batch you're buying.
Start by locating the cannabinoid profile section. Look for two key fields: delta-9 THC and total THC.
The designation "ND" means "non-detectable" - THC levels are below the lab's detection limit.
This doesn't guarantee zero, but it's as close as you can verify.
Match the batch number on your product packaging to the batch number on the COA.
Different numbers mean you're looking at results from a different batch entirely, which makes the COA useless for verification.
Pay attention to the testing lab's accreditation.
Look for ISO 17025 certification, which indicates the lab follows strict quality standards and undergoes independent audits.
Vape products deserve extra scrutiny because of higher contamination and mislabeling risks.
Multiple online communities report experiences with supposedly pure CBD vapes that created unexpected highs.
All of our products link directly to current, batch-matched COAs. We work exclusively with ISO-accredited facilities because verification should be straightforward, not detective work.
Once you know how to read a COA, you'll understand more about product safety than most CBD shoppers. This knowledge protects you from mislabeled or contaminated products.
What CBD Actually Feels Like and When
Most people describe CBD as creating calm and balance without intoxication. The onset timing varies dramatically by format.
Inhaled CBD (vapes, flower) works within 5-10 minutes. Edibles take 30-90 minutes to kick in.
Sublingual oils fall somewhere in between, typically producing effects within 15-45 minutes.
The faster onset doesn't mean stronger effects - just quicker timing.
Some people report drowsiness or mental fog at higher CBD amounts.
Individual responses vary, which is why starting low and increasing gradually makes sense.
Johns Hopkins researchers found that CBD consumed with THC edibles can increase THC's effects through metabolism interactions. This matters if you're using products that contain both cannabinoids.
The interaction means that a small THC amount combined with CBD might feel stronger than the same THC amount alone.
Keep this in mind when trying mixed-cannabinoid products like our balanced gummies.
Understanding timing helps prevent a common mistake: taking more because you "don't feel anything yet." Patience with onset differences reduces the risk of overdoing it.

Finding Your CBD Amount Without Overdoing It
There's no universal CBD amount that works for everyone. Body weight, metabolism, and individual sensitivity all play roles.
Starting conservatively and increasing gradually gives you control over the experience. Many people begin with 10-15mg of CBD and adjust from there.
Spacing your amounts based on onset timing prevents stacking.
If you take another serving before the first kicks in, you might end up with more intensity than intended.
For THC-sensitive users, isolate or broad-spectrum products with verified non-detectable THC provide the safest entry point. These options eliminate the variable that causes the most concern.
Track how different amounts affect you and adjust accordingly.
What works for a relaxing evening might be different from what helps you stay focused during the day.

When CBD Makes People Feel High Anyway
Some people do feel unexpectedly buzzed from CBD products. There are several likely explanations.
Full-spectrum products at high CBD amounts contain accumulated trace THC.
Taking 100mg of CBD from a full-spectrum product could mean consuming 3-5mg of THC.
Mislabeled products represent another common cause, especially with vapes.
Some manufacturers don't maintain consistent quality control, and what's on the label doesn't always match what's in the product.
Contaminated or intentionally spiked products occasionally appear in the market. This is why purchasing from transparent companies with verified testing matters.
Individual sensitivity varies more than most people realize.
A trace amount that one person doesn't notice might be enough for someone else to feel.
If you've felt high from a supposedly non-intoxicating CBD product, you're not imagining things and you're not uniquely sensitive.
The most likely explanation is that the product contained more THC than you expected.
Returning to COA verification and spectrum choice prevents most surprises.
Knowing what you're actually consuming eliminates guesswork.
CBD and Drug Tests in Plain English
Hemp-derived CBD is federally legal when it contains less than 0.3% delta-9 THC by dry weight.
This is the standard set by the 2018 Farm Bill.
However, trace amounts of THC can accumulate with regular use. Even products with very low THC content might lead to positive drug test results over time.
Products with verified non-detectable THC reduce this risk significantly.
They don't eliminate it entirely because "non-detectable" means below measurement thresholds, not absolute zero.
If your employment involves drug testing, the safest approach is complete transparency with your employer or choosing CBD isolate products with documented zero THC.
Even then, no hemp product offers absolute guarantees.
THC stores in fat cells, so individuals with higher body fat percentages may test positive longer.
Metabolism, hydration levels, and test sensitivity all factor into the equation.
We provide detailed information about different THC types and how they appear in products and tests, helping you make informed decisions based on your specific situation.

Your Plan for CBD Without Surprises
You now understand that the 0.3% THC limit is a weight percentage, not a guarantee against feeling effects.
A compliant product can still contain enough THC to notice.
Choose your spectrum type based on THC sensitivity. Isolate or broad-spectrum with verified non-detectable THC gives you the most control.
Verify THC content using batch-matched COAs before purchasing. Look for "ND" designations under delta-9 THC if avoiding any THC exposure is your goal.
Start with conservative CBD amounts and increase gradually based on your response.
Pace your amounts according to format timing to prevent accidental stacking.
You have the tools to make informed choices instead of relying on trial and error. Understanding these fundamentals transforms confusion into confidence.
