Quick Safety and Legality Notes

In the U.S., “hemp” is federally defined as cannabis with ≤0.3% delta‑9 THC by dry weight (2018 Farm Bill). Some states have stricter rules for possession, processing, and retail sales. Always check your local laws.

• Only one CBD drug (Epidiolex) is FDA‑approved for specific seizure disorders.
• Over‑the‑counter CBD products are not FDA‑approved to diagnose, treat, cure, or prevent disease.
• Talk to your healthcare provider before use—CBD can interact with medications.

For official updates, see the FDA’s consumer guidance and your state’s hemp program page.

A–Z CBD Glossary Terms

A

• Acidic Cannabinoids (CBDA, THCA): Precursor forms that convert to “neutral” cannabinoids (CBD, THC) when heated through decarboxylation.
• Administration Route: How you take CBD—sublingual, oral, topical, inhalation—each with different onset and duration.
• Agricultural (Industrial) Hemp: Cannabis sativa L. legally grown with ≤0.3% delta‑9 THC by dry weight in the U.S.
• Aroma/Terpene Profile: The scent/flavor fingerprint created by terpenes like limonene, myrcene, and pinene.

B

• Batch Number: A unique code on labels that ties your product to a specific lab report (COA).
• Bioavailability: How much CBD actually reaches circulation; varies by method (inhalation > sublingual > oral).
• Broad‑Spectrum: Hemp extract with multiple cannabinoids/terpenes and non‑detectable THC.

C

• Cannabidiol (CBD): A non‑intoxicating cannabinoid studied for a range of potential effects; not FDA‑approved for general wellness claims.
• Cannabinoids: Active compounds in cannabis (e.g., CBD, THC, CBG, CBN) that interact with the body’s ECS.
• Cannabis sativa L.: The plant species encompassing both hemp and marijuana varieties.
• Carrier Oil: The base oil (MCT, hemp seed, olive) that dilutes CBD extract for consistency and absorption.
• CBG (Cannabigerol): A “minor” cannabinoid; precursor to other cannabinoids in the plant.
• CBN (Cannabinol): A cannabinoid that can form as THC oxidizes; sometimes found in aged extracts.
• CBD Isolate: Purified CBD (typically 98–99%+) without other cannabinoids or terpenes.
• CO2 Extraction: A solvent‑free extraction method using pressurized carbon dioxide to pull actives from hemp.
• COA (Certificate of Analysis): Third‑party lab report confirming potency (mg of cannabinoids), safety (contaminants), and compliance.

D

• Decarboxylation: Heating cannabis to remove a carboxyl group (COOH), converting CBDA to CBD and THCA to THC.
• Delta‑9 THC: The primary intoxicating cannabinoid in cannabis; federally limited to ≤0.3% in hemp products by dry weight.
• Delta‑8 THC: A psychoactive isomer that may be synthesized from CBD; legality varies by state.
• Distillate: A refined, concentrated extract rich in target cannabinoids.
• Dosage vs. Serving: “Serving” is what the label suggests; “dosage” is what you actually take based on your needs and provider guidance.

E

• Endocannabinoid System (ECS): A body‑wide network (CB1/CB2 receptors, endocannabinoids, enzymes) that helps maintain balance.
• Endocannabinoids (AEA, 2‑AG): Compounds your body makes that interact with the ECS.
• Entourage Effect: Theorized synergy among cannabinoids, terpenes, and flavonoids.

• GRAS: “Generally Recognized as Safe” designation. Note: certain hemp seed ingredients are GRAS; CBD isolate is not GRAS for foods.

H

• Hemp: Cannabis with ≤0.3% delta‑9 THC by dry weight; source of most U.S. CBD products.
• Hemp Extract: Concentrated cannabinoids/terpenes from hemp plant material.
• Hemp Seed Oil: Nutrient‑rich food oil from seeds; typically contains little to no CBD.
• Homogenization: Mixing process that evenly disperses CBD throughout a product.

I

• Isolate (CBD Isolate): Single‑molecule CBD without other plant compounds.
• Inhalation: Vaporizing or smoking; fastest onset, shorter duration. Follow local laws and health guidance.
• Infusion: Soaking plant material in a carrier oil to transfer cannabinoids and terpenes.

J

• Joint (Hemp): A pre‑rolled smokable hemp product, where legal; verify COA and local regulations.

K

• Kief: Concentrated trichomes collected from hemp flower; rich in cannabinoids and terpenes.
• Kosher Certification: Indicates compliance with kosher food standards where applicable.

L

• Label Claims: Statements on packaging; should be truthful and substantiated by COAs.
• Limonene: A citrus‑scented terpene often found in hemp varieties.
• Lipid Infusion: Using fats (e.g., MCT) to extract and carry cannabinoids.
• Lab Shopping: Unethical practice of seeking favorable lab results; a red flag.

M

• MCT Oil: A common carrier oil made from medium‑chain triglycerides (often coconut‑derived).
• Microdosing: Taking very small amounts to gauge sensitivity and effect.
• Minor Cannabinoids: Less abundant compounds (e.g., CBC, THCV) present in small amounts.
• Milligram (mg): The unit used to measure CBD potency per serving or per bottle.

N

• Nanoemulsion: Very small oil droplets dispersed in water; may help uniformity and mouthfeel.
• ND (Non‑Detect): A lab result below the instrument’s limit of detection for a compound.

O

• Organic Certification: USDA or accredited body verifying organic practices; check labels carefully.
• Oxidation: Chemical change from oxygen exposure; can degrade cannabinoids over time.

P

• Pesticide Screen: COA section showing whether regulated pesticides are present.
• Phytocannabinoids: Cannabinoids made by plants, including hemp.
• Potency: The concentration of cannabinoids, typically reported in mg per serving.

• Whole‑Plant: Extract that preserves a broader spectrum of hemp compounds.
• Winterization: Chilling extract in ethanol to remove waxes and lipids for clarity.

X

• Xylenes: Organic solvents monitored in residual solvent tests; should be non‑detectable in finished product.

Y

• Yield: The amount of extract obtained from a given amount of plant material.
• Young Plants (Seedlings): Early growth stage; genetics, light, and nutrients shape the final chemotype.

Expert Tips: How to Read a COA (Certificate of Analysis)

1. Match Identifiers: Confirm brand, product name, and batch/lot number on both label and COA.
2. Check Potency: Review CBD mg per serving/bottle. Ensure delta‑9 THC is compliant (≤0.3% by dry weight for hemp).
3. Review Safety Screens: Look for “Pass” on:
   • Pesticides
   • Heavy metals (lead, arsenic, cadmium, mercury)
   • Residual solvents (e.g., xylenes, ethanol)
   • Microbials (E. coli, Salmonella)
   • Mycotoxins
   • Foreign matter
4. Verify Date and Lab: Recent testing by an ISO‑accredited lab is preferred.
5. Scan the QR Code: Ensure it links directly to the COA hosted by the lab or brand.
6. Look for ND vs. 0: “Non‑detect” means below detection limits, not necessarily zero.
7. Compare Spectrum: Full‑spectrum should show a range of cannabinoids; isolate should show CBD only.

Experience: A Real‑Life Example

Maya, a distance runner, wanted a topical for post‑run routines. She chose a 1,000 mg CBD balm from a reputable brand. Before buying, she:

• Compared products using this hemp vocabulary and the COA checklist.
• Scanned the QR code to confirm potency and clean contaminant screens.
• Patch‑tested a small area and tracked use in a simple journal.

Over three weeks, she noted how the balm fit into stretching and recovery. The structured approach—COA verification, slow and steady testing, and journaling—helped her decide what to repurchase. Individual experiences vary, and this isn’t medical advice.

Smart Shopping: Quick Checklist

• Clear label with batch number and mg of CBD per serving
• Accessible third‑party COA for the exact batch
• Accurate spectrum claims (full, broad, isolate)
• Responsible marketing (no cure‑all claims)
• Responsive customer support and transparent sourcing
