What THC and CBD Are

THC (tetrahydrocannabinol) is the primary psychoactive cannabinoid in cannabis. It binds to CB1 receptors in the brain and central nervous system, producing intoxication at sufficient doses. At therapeutic doses, THC has documented clinical effects including analgesia, appetite stimulation, nausea reduction, muscle relaxation, and sleep facilitation. THC above 0.3% is federally scheduled and requires an MMJ card for legal access in Florida.

CBD (cannabidiol) is non-intoxicating. It interacts with the endocannabinoid system through different mechanisms — primarily CB2 receptors and indirect endocannabinoid modulation — and does not produce intoxication at any dose. Hemp-derived CBD products containing 0.3% THC or less are legal in Florida without a card and widely available in retail stores and pharmacies.

Clinical Differences

  • Pain: THC and combined THC/CBD formulations have the stronger evidence base for chronic pain management. CBD alone demonstrates some analgesic effects but is less well-established for significant chronic pain.
  • Anxiety: CBD has demonstrated anxiolytic effects at therapeutic doses. High-dose THC can increase anxiety in some patients — particularly those without prior cannabis exposure. Low-dose THC may reduce anxiety; high-dose THC may worsen it.
  • Sleep: THC has documented effects on sleep onset. CBD's effects on sleep are less consistent in the clinical literature.
  • Seizures: CBD has the strongest single-cannabinoid clinical evidence — Epidiolex (purified CBD) is FDA-approved for specific seizure disorders. THC also has anticonvulsant properties.
  • Nausea: THC and THC-dominant formulations have strong evidence for nausea reduction, particularly chemotherapy-induced nausea.

Full-Spectrum vs Isolated

Full-spectrum cannabis products — containing both THC and CBD along with other cannabinoids and terpenes — may produce different effects than isolated cannabinoids. Many patients report better results from full-spectrum dispensary products than from CBD isolate alone. The clinical evidence for this "entourage effect" is still developing, but it is a meaningful consideration for product selection at the dispensary.

Frequently Asked Questions

What is the difference between THC and CBD?

THC is the primary psychoactive cannabinoid — intoxicating at sufficient doses and requiring an MMJ card for legal access above 0.3% in Florida. CBD is non-intoxicating, available without a card in hemp-derived form (0.3% THC or less), and has a distinct clinical profile especially in seizure disorders.

Do I need an MMJ card to buy CBD in Florida?

No. Hemp-derived CBD products (0.3% THC or less) are legal without a card. Products with more than 0.3% THC — including full-spectrum dispensary products — require an active Florida MMJ card.

Which is better for pain — THC or CBD?

For significant chronic pain, the clinical evidence base is stronger for THC and combined THC/CBD products. CBD has some analgesic effects but the evidence is less robust. Discuss your specific pain pattern with Dr. Sadow at your evaluation.

Can I get products with both THC and CBD at a Florida dispensary?

Yes. Licensed Florida dispensaries carry a wide range of products with varying THC/CBD ratios — CBD-dominant, balanced 1:1, or THC-dominant. Your certification specifies approved delivery methods; product selection within those methods is made at the dispensary.

Why is CBD available without a card but THC is not?

The 2018 Farm Bill federally legalized hemp-derived CBD products containing 0.3% THC or less. THC above that threshold remains Schedule I federally. Florida's MMJ program — with physician certification and OMMU registration — is the legal framework for accessing THC-containing products.
