What this page doesn’t cover
This page does not provide medical recommendations, detailed legal advice for specific jurisdictions, or a full comparison of full‑spectrum vs broad‑spectrum products. For product selection or legal questions consult the appropriate professionals.
Key definitions
- THC‑free: A label term generally meaning no detectable Δ9‑THC in the final product. Exact meaning depends on the testing method and the lab’s limit of quantification (LOQ).
- CBD isolate vs broad‑spectrum: Isolate is purified CBD with no other cannabinoids; broad‑spectrum typically retains other cannabinoids and terpenes but claims non‑detectable THC.
- Certificate of Analysis (COA): A third‑party lab report showing cannabinoid concentrations, contaminants, and often detection limits (LOQs).
- Limit of Quantification (LOQ): The smallest concentration the lab can reliably quantify. “Non‑detect” or “< LOQ” means any THC present is below that threshold—not necessarily absolutely zero at a molecular level.
Main factors that drive price
- CBD potency (mg per bottle): More milligrams of CBD in the same package size usually raises the price but lowers per‑mg cost.
- Extraction method: Supercritical CO2 extraction tends to cost more than crude solvent extraction but is preferred for purity and consistency.
- Purification and testing: Extra steps to remove THC (e.g., repeated distillation) and full third‑party testing add to cost.
- Source and compliance: Hemp grown under certified programs and compliant supply chains can increase price compared with uncertified sources.
- Formulation & delivery format: Tinctures, capsules, gummies, and topicals have different processing costs; specialized delivery tech (nanoemulsions) also increases price.
- Branding, packaging & customer support: Reputation, guarantees, and transparent COAs add perceived value and cost.
How to compare prices sensibly
Per‑mg cost (standard comparison)
Calculate price per milligram of CBD to compare products with different potencies:
price per mg = product price ÷ total CBD mg
Example: a 30 mL tincture labeled 1500 mg at $60 → $60 ÷ 1500 mg = $0.04 per mg.
Consider usable CBD vs labeled CBD
Use batch‑specific COAs (not just label claims) to confirm total CBD. Brands that publish batch COAs let you verify the numerator and denominator in the per‑mg calculation.
Factor in dosing and expected duration
Estimate how long a product will last based on your target dose. Example: at 25 mg/day, a 1500 mg bottle provides 60 days of supply (1500 ÷ 25 = 60).
Typical market ranges (approximate)
These are approximate, marketwide ranges to give context; actual prices vary by brand, region, and quality.
- THC‑free CBD tinctures / oils: roughly $0.03–$0.12 per mg.
- Capsules / softgels: generally a bit higher per mg due to manufacturing—often $0.05–$0.15 per mg.
- Topicals: price per mg of CBD is less meaningful; expect higher per‑mg costs because of additional ingredients and formulation work.
- Gummies: price per mg varies widely based on recipe and dosing—typically higher than tinctures.
Interpreting COAs and LOQs (practical guide)
- Always look for a batch‑specific COA showing cannabinoid panel, heavy metals, solvents, and pesticides.
- Check how THC is reported: look for numerical values and the LOQ. If COA lists THC as “< LOQ,” note the LOQ value (e.g., 0.01 mg/g). That tells you the lab’s detection capability.
- Understand units: labs may use mg/g, mg/kg, or ppm. Convert if necessary so you can compare across products.
- Confirm the lab is independent and accredited; COAs from vendor‑owned labs are less independent in perception.
Drug testing and THC‑free products
Important considerations:
- “THC‑free” typically means THC below the lab’s LOQ, not necessarily absolute zero molecules; some COAs will show “non‑detect.”
- Many employer drug tests look for metabolites of Δ9‑THC; extremely low or trace THC in a product could theoretically contribute to a positive test if consumed in large quantities over time, but outcomes depend on test sensitivity, individual metabolism, dose, and frequency.
- To reduce risk: select products with a clear, low LOQ on the COA, choose CBD isolate if you need the strictest option, and keep purchase records and COAs to show if questions arise.
- When drug‑testing risk is high, consult your employer’s testing policy or a qualified expert. This page does not guarantee safety from positive tests.
Practical buying checklist
- Verify batch COA (cannabinoids + contaminants) and note the LOQ for THC.
- Calculate price per mg using COA‑confirmed CBD content.
- Prefer CO2 extraction or clearly documented methods and low‑residual solvent results.
- Check hemp source and manufacturing transparency (country of origin, cultivation practices).
- Look for return policies, clear labeling, and customer support contact info.
- Avoid unrealistic potency claims (e.g., extremely high mg in small volumes without COA evidence).
Common pitfalls and red flags
- No batch COA published or COA is not batch specific.
- Lab reports that omit LOQ values or use unclear units.
- Vague “THC‑free” claims with no testing to back them up.
- Unusually low price per mg compared to market norms—may indicate diluted product or inaccurate labeling.
- No third‑party testing for contaminants (heavy metals, solvents, pesticides).
Budgeting examples
Example A — Budget‑conscious: 750 mg bottle for $30 → $30 ÷ 750 mg = $0.04 per mg. If you dose 20 mg/day → bottle lasts 37.5 days.
Example B — Higher‑potency, premium: 3000 mg bottle for $180 → $180 ÷ 3000 mg = $0.06 per mg. If you dose 25 mg/day → bottle lasts 120 days.
Use these calculations to estimate monthly cost: monthly cost = daily dose (mg) × price per mg × 30.
FAQs
1. How do I calculate the price per mg of CBD?
Divide the product price by the total CBD milligrams (confirmed on the product label or, better, the batch COA). Example: $50 ÷ 1000 mg = $0.05 per mg.
2. Does a higher price mean higher quality?
Not always. Higher prices can reflect better sourcing, testing, or formulation, but they can also reflect branding. Verify quality through batch COAs, test methods, and transparent manufacturing information.
3. What does “THC‑free” actually guarantee?
“THC‑free” commonly means THC is below the lab’s LOQ or not detected on a third‑party test. Check the COA and LOQ to understand what the label claim means in practice.
4. Can THC‑free CBD cause a positive drug test?
There is no absolute guarantee. If a product contains THC below LOQ, the risk is lower but not necessarily zero—especially with high or long‑term use. If drug testing is a concern, choose products with low LOQs, obtain COAs, or consult a testing policy expert.
5. How often should I expect to re‑purchase?
That depends on your daily dose. Calculate bottle duration by dividing total CBD mg by your daily intake (mg/day). This gives an estimate of days of supply.
6. What should I do if a COA looks confusing or incomplete?
Contact the brand and request a batch‑specific COA with clear units and LOQs. If the brand cannot provide one, consider alternatives with transparent lab documentation.
