No federal regulation means the quality gap between CBD products is enormous. Here's the 5-step checklist for evaluating any CBD product before you buy.
The 5-Step Quality Check
1. Find the COA
A Certificate of Analysis from an independent, accredited lab is the single most important document. It should be batch-specific (not a generic "representative" report), recent (within 12 months), and cover: cannabinoid potency, pesticides, heavy metals, residual solvents, and microbial contaminants. No COA = no purchase.
2. Verify Label Accuracy
Compare the COA's CBD content to the label claim. Reputable products test within 10% of stated amount. A 2017 JAMA study found 1 in 4 CBD products tested contained less CBD than labeled. This is still the norm for low-quality brands.
3. Check Extraction Method
CO2 extraction = gold standard. Ethanol = acceptable. Hydrocarbon (butane/propane) = avoid unless COA confirms clean residual solvent results. If the brand doesn't disclose their extraction method, that's a red flag.
4. Understand the Spectrum
Full-spectrum (includes trace THC + entourage effect) generally outperforms isolate in studies. Choose broad-spectrum if you need zero THC for drug testing. Isolate is cheapest but least effective.
5. Start Low, Go Slow
10–25mg/day to start. Sublingual delivery (under the tongue, held 60 seconds) has better bioavailability than capsules or gummies. Give each dose 5–7 days before adjusting.
Red Flags to Avoid
- Disease claims ("cures cancer," "treats diabetes")
- No third-party COAs or in-house testing only
- CBD content significantly below label claims
- "Hemp extract" without specifying CBD milligrams
- No identifiable company or customer service contact
A Brand That Gets It Right
Populum checks every box: CO2 extraction, batch-specific COAs from independent labs, full-spectrum formulation, CBD content within 5% of label claims, and a 30-day risk-free trial. They're the standard we recommend for first-time buyers who want transparency they can verify.
