Scientific Overview

How Does CBD Work?

CBD (cannabidiol) is a non-intoxicating compound found in hemp (Cannabis sativa). The endocannabinoid system (ECS), including CB1 and CB2 receptors, helps the body maintain balance. Research on how CBD interacts with the ECS is still ongoing.

Some research suggests CBD interacts with the ECS indirectly rather than by activating receptors in the usual way. Scientists are still studying the exact mechanism and effects, so we focus on THC-free products with lab results available to review. See the “What is CBD?” page for more information.

THC-Free, Broad Spectrum

USA Medical products use THC-free, broad-spectrum CBD extracts—cannabinoids and terpenes without THC—so they are non-intoxicating. THC is the psychoactive component and is excluded from our products. More details are available on the CBD oil category page.

Important Note

If you have a health condition or take medication, talk with your healthcare professional before using CBD products.

Frequently Asked Questions

  • Which CBD oil is the best choice? — Many customers start with the 1000 mg oil. The 500 mg and 1000 mg options are common starting points, while the 3000 mg option is often the most economical choice for customers who want a higher-strength format.
  • How long does a 1000 mg bottle last? – About 3 months if used at 10 drops daily.
  • THC-free CBD oils are made without THC and are not intended to cause intoxication.
  • Where is the CBD extract made? — It’s produced in the USA in GMP-compliant facilities and tested by independent laboratories.
  • What percentage of CBD is in USA medical CBD oils? – The percentage can be misleading, so the manufacturer specifies the CBD content in mg per product for more accurate comparisons.
  • Is CBD oil legal? — CBD laws vary by location. USA Medical CBD oils are THC-free. Check current local rules before purchasing.
  • How do I calculate the dosage? — A 30 mL bottle contains about 1,000 drops. The amount per drop depends on the concentration (for example, 500 mg ≈ 0.5 mg/drop; 1000 mg ≈ 1 mg/drop; 3000 mg ≈ 3 mg/drop). Check the label, start with a low amount, and adjust gradually.
  • Is it safe during pregnancy or breastfeeding? — CBD is not recommended during pregnancy or breastfeeding because research is limited. Talk with a healthcare professional if you have questions.
