For more than a decade, we’ve asked questions, tested what we make, studied the science, and kept looking for better answers. Today, proprietary technology, a portfolio of cannabinoid patents, and a leading body of peer-reviewed research are at the core of what we do. From the genetics of the plant to what’s inside every bottle, every detail matters, because trust is earned through the work behind it.
From seed to shipment
“We have traceability from the minute the seed goes into the ground until the package goes out of the warehouse for shipping.”
Dr. Marcel Bonn-Miller, Chief Scientific Officer
Quality standards
Select a step to see what happens, what we test, and how we hold the line on quality.
Step 01 · Genetics
Our proprietary hemp genetics have been developed over more than a decade and remain the foundation of our full-spectrum extracts.
Step 02 · Cultivation
Quality starts long before extraction. How hemp is grown, harvested, and handled helps determine the quality of what comes next.
Step 03 · Extraction
Our extraction process is designed to preserve the naturally occurring compounds of the hemp plant and create the full-spectrum extracts at the heart of our products.
Step 04 · Testing
Independent third-party laboratories test our products to verify cannabinoid content and screen for contaminants before they reach you.
Step 05 · Transparency
We believe you should be able to know what’s in the product you use. Batch results give you a way to see the testing behind your product for yourself.

The endocannabinoid system, or ECS, is a signaling system found throughout the body. It plays a role in regulating processes including sleep, mood, pain, immune function, and stress response.
Cannabinoids are compounds found in hemp that can interact with the ECS in different ways. Understanding those interactions, and what they may mean for human health, continues to be an important area of scientific research.
Found primarily in the brain and nervous system, with roles in functions including mood, memory, appetite, pain, and movement.
Found throughout the body, particularly in cells associated with the immune system, and studied for their role in immune signaling and inflammation.
Hemp contains many naturally occurring compounds, including cannabinoids, terpenes, and flavonoids. Researchers continue to study how these compounds work individually and together, and what those interactions could mean.
Go deeper into the ECS. Our guide to the endocannabinoid system takes a closer look at how it works and what researchers are continuing to learn.
Scientific Advisory Board

Chief Scientific Officer, Charlotte’s Web · Chair, Scientific Advisory Board
Dr. Marcel Bonn-Miller earned a BA in psychology and PhD in clinical psychology from the University of Vermont and completed his Postdoctoral Fellowship at Stanford University School of Medicine. He began his career at the Department of Veterans Affairs and the Department of Psychiatry at the University of Pennsylvania, where he built and directed two fully grant-funded cannabis research centers. He then transitioned to industry roles as Director of Cannabinoid Research at Zynerba Pharmaceuticals, Vice President of Human and Animal Research at Canopy Growth Corporation, and currently serves as Chief Scientific Officer at Charlotte’s Web.
Widely considered one of the early and leading research pioneers in the field of cannabis and mental health, Dr. Bonn-Miller has conducted seminal work on the interrelations between cannabis/cannabinoids and a range of health conditions, including pain, anxiety, HIV, PTSD, and sleep disorders. He brings a unique perspective to cannabinoid therapeutics, having worked in medical center and academic settings for over a decade and within industry for the past 9 years. He serves on the editorial boards of several scientific journals and has published over 175 peer-reviewed empirical publications on cannabis.

Research & Discovery
For more than a decade, we’ve studied hemp, cannabinoids, and the science behind them. That work has helped deepen our understanding, inform what we make, and open the door to entirely new areas of research.
What we’ve learned
Studies designed to better understand cannabinoids and their potential role in health and wellness.
Research examining how hemp-derived cannabinoids are used and tolerated.
Work alongside researchers, universities, and scientific organizations to advance cannabinoid knowledge.
Peer-reviewed findings that contribute to the broader body of cannabinoid science.
Where that science is leading
Charlotte’s Web co-founded DeFloria, a clinical-stage botanical pharmaceutical venture developing AJA001, an investigational botanical drug derived from Charlotte’s Web’s proprietary full-spectrum hemp genetics. DeFloria is advancing AJA001 through Phase 2 clinical trials under the FDA Botanical Drug Pathway for irritability associated with autism spectrum disorder.

Every study gives us something new to understand, and every answer opens the door to another question. So we’ll keep following the evidence, challenging what we know, and doing the work to discover what comes next.
