HelloPharmacist Scorecard of CBN Tablets 1000 mg THC-Free by FluxxLab

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 3 active ingredients.

This product contains 3 active ingredients: Total Cannabinoids, Cannabinol, and Phytocannabinoid-Rich Hemp extract, each contributing to the 1000 mg total per tablet. The hemp extract is the ingredient we have the most data on; the other two are cannabinoid compounds.

The tablet also contains several inactive ingredients—calcium hydroxyphosphate, magnesium stearate, microcrystalline cellulose, dicalcium phosphate, and silicon dioxide—which are standard binders and fillers used to form and stabilize the tablet.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Hemp product and its label doesn't state a use — see Hemp's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence on these ingredients isn't established in our data. The hemp extract has been studied for constipation, atopic dermatitis (eczema), and familial hypercholesterolemia (a genetic cholesterol condition), but in each case the research is insufficient to reliably rate whether it works.

We don't hold effectiveness ratings for the other two active ingredients.

The evidence, ingredient by ingredient Hemp

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Hemp seed products in food amounts are generally well tolerated. Concentrated extracts and supplements like this one are much less studied, so caution is advised.

Serious adverse effects are rare but have been reported: occasional cases of allergic reactions (hives, facial swelling, shortness of breath, and in rare instances anaphylaxis) and very rare reports of heart rhythm problems. One case of elevated liver enzymes and hepatitis occurred in a young child given very high doses of hemp extract for seizures—the dose was far larger than what's in this tablet.

Pregnancy and lactation safety information is not on file for these ingredients. If you're pregnant or nursing, talk with your pharmacist or doctor before taking this product.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Hemp.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 939 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check these medication types with your pharmacist before taking this product: estrogen therapy (Moderate concern), blood pressure medications (antihypertensive drugs and ACE inhibitors), blood thinners and antiplatelet drugs, and any drugs that rely on liver enzymes CYP1A2 or CYP3A4 for how your body clears them.

The bottom line

Scorecard at a glancePartially disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may interest you if you're exploring cannabinoids and want a THC-free option. However, if you take blood pressure medications, blood thinners, estrogen therapy, or drugs processed through your liver's CYP1A2 or CYP3A4 pathways, check your exact medications with the tool on this page first.

Talk to your pharmacist—they can tell you whether it's safe for your specific situation.

Phytocannabinoid-Rich Hemp extract6 drug types · 938 drugs

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that hemp induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that hemp induces CYP3A4 enzymes.

CBN Tablets 1000 mg THC-Free by FluxxLab: Common Questions

Does CBN Tablets 1000 mg THC-Free by FluxxLab interact with any medications?
Yes. Based on its ingredients, CBN Tablets 1000 mg THC-Free has a known interaction with 938 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CBN Tablets 1000 mg THC-Free contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this with my blood pressure medication?
Possibly—but it needs checking first. Hemp extract may have additive effects with blood pressure meds, which could lower your pressure further. Use the medication checker on this page with your drug name, or ask your pharmacist if it's safe to combine.
Is this safe during pregnancy or breastfeeding?
We don't have safety data on file for these ingredients in pregnancy or lactation. Don't guess—talk with your pharmacist or doctor for personalized advice before you take it.
What is hemp extract, and how is it different from cannabis?
Hemp extract comes from the hemp plant and contains phytocannabinoids. This product is labeled THC-free, so it shouldn't contain THC (the compound in cannabis that gets you high). Hemp extract and cannabis are related plants but are processed differently.
Are there any serious side effects I should watch for?
Serious effects are rare. Allergic reactions—including hives, facial swelling, shortness of breath, and very rarely anaphylaxis—have been reported. Very rare cases of heart rhythm problems have also been noted. Stop and seek help immediately if you have signs of an allergic reaction.
Does this product actually work for the reasons it's sold?
The evidence isn't clear enough yet. Hemp extract has been studied for constipation, eczema, and high cholesterol, but the research so far is insufficient to say whether it reliably works for any of them.
What are the inactive ingredients, and are there fillers?
Yes, this tablet contains fillers and binders: calcium hydroxyphosphate, magnesium stearate, microcrystalline cellulose, dicalcium phosphate, and silicon dioxide. These are standard and help form the tablet.
