After our son Zack's near-fatal car accident in February 2019, we tried everything we could to help him.  I went to a store in Lubbock, Texas, that sold a CBD oil with no THC.  I gave it to him several times a day.  The Doctors and other staff were so amazed at how well he did, considering he was not expected to survive the accident. 

After we got him home, we tried everything from heavy painkillers and blockers to deal with his nerve pain, and using my Anti-inflammatory Protocol religiously, even through his feeding tube, we could not seem to relieve him of enough pain for him to be able to function.  In April of 2019, we tried CBD with THC.  After 2 doses, Zack's headache (he didn't realize he had) went away.  After 3 doses (six drops), his nerve pain was gone.  I had used THC in the past for seizures, cancer pain, and nausea, but had not used it as of yet for TBI.

Below is all you need to know about CBD with THC and the process.  Not only has this helped my son, but many, many others whom we have recommended it to all over the world.  Give it a try!  If you have any questions, you can reach out to me or Zack anytime!!

Everything You Need to Know About CBD Extraction (2025 Update)

CBD Extraction Methods

CO2 Extraction


CO2 extraction is the most advanced and precise method, producing potent, safe, and solvent-free CBD. Using a closed-loop extractor, CO2 in a supercritical state passes through cannabis plant material, separating cannabinoids into a highly pure fluid. While expensive and technically demanding, it produces one of the highest-quality CBD products.

Liquid Solvent Extraction (Ethanol, Butane, Alcohol)


Solvent extraction is faster and cheaper but less ideal. It strips cannabinoids from the plant, but may destroy valuable compounds, leave harmful residues, and is highly flammable—making it risky for consumer products.

Olive Oil Extraction


Olive oil extraction is safe and simple, but it's best for small-scale or home use. After decarboxylating the plant, cannabinoids are extracted into the oil. The resulting product is less concentrated and perishable, requiring careful storage.

Whole Flower (Proprietary / Cold Press)


Modern whole flower extraction preserves all plant components, maximizing bioavailability and benefits. This method maintains cannabinoids, terpenes, and flavonoids together, supporting the “entourage effect” for superior results.

CBD Spectrum: Full, Broad, or Isolate

Full-Spectrum CBD


Contains CBD plus a full range of cannabinoids, terpenes, flavonoids, and other compounds. The combined effect, known as the entourage effect, enhances therapeutic benefits. Research shows full-spectrum products often outperform isolates at similar doses.

Broad-Spectrum CBD


Includes multiple cannabinoids and compounds but typically no THC. The term is loosely defined; products vary widely in composition.

CBD Isolate


Pure CBD with no additional cannabinoids or terpenes. While dosing is straightforward, isolates may be less effective due to the absence of the entourage effect.

Bottom Line: Full-spectrum CBD is generally the most effective and beneficial, though individual responses vary.

Finding the Right CBD Dosage

Determining the correct dosage is complex because the effects depend on:

  • The cannabis plant used

  • The extraction method

  • The CBD spectrum (full, broad, isolate)

Full-Spectrum CBD: Requires the lowest dose due to the entourage effect. Start low and increase gradually if needed.

Note: Research is still ongoing. The only FDA-approved CBD drug is Epidiolex for certain seizure disorders. For other CBD products, efficacy varies, so consult your physician for guidance.
