A quick, honest note
A lot of the cannabis claims you’ll run into come from cell and animal studies, and those results often don’t carry over to people. No one can promise what cannabis will do for you, because every body processes it differently. This book marks which findings come from human studies and which come from the lab, so you can keep your expectations grounded and talk it through with your clinician.
Who it’s for
- Adults new to medical cannabis who want a solid starting map
- Caregivers helping a loved one understand the basics
- Anyone who takes other medicines and wants to know which interactions to ask about
- Professionals who want a clear foundational reference
Who it’s not for
- Anyone looking for “cures,” dosing prescriptions, or product hype
- Anyone hoping to skip their clinician. The book is built to help you talk with yours.
- Readers who want product or brand recommendations. The book makes none.
- Anyone under 21
What’s inside, chapter by chapter
The book opens with a note from Shawn about how he came to cannabis. After that, nine chapters move from how cannabis works to how to use that knowledge safely.
A Note from Shawn
How a prostate cancer survivor came to cannabis, why he wrote the book, and why cannabis was never a treatment for his cancer.
Chapter 1: How Cannabis Works in the Body: The Endocannabinoid System
The signaling network your body already has, the CB1 and CB2 receptors, your body’s own cannabis-like molecules, and the wider system researchers now call the eCBome.
Chapter 2: Cannabinoids 101: THC, CBD & the Minor Players
What THC and CBD do, why the ratio and the condition both matter, the minor cannabinoids (CBG, CBN, CBC, THCA, delta-8), and why labels can mislead.
Chapter 3: Terpenes and the Entourage Effect
What terpenes are, what’s tentatively known about the best-studied ones, why the entourage effect is still unproven, and how to read terpenes on a label or lab report.
Chapter 4: Routes of Administration & Timing
Inhaled, under the tongue, swallowed, and on the skin. How each one changes onset, peak, and duration, and why edibles are easy to overdo.
Chapter 5: Starting Low and Going Slow
What published guidance says about starting amounts, why THC is biphasic, and why your clinician stays involved. It gives no dose, schedule, or target for you.
Chapter 6: Drug Interactions & Medication Safety
How liver-enzyme interactions work, the best-documented cases (such as warfarin and clobazam), how drowsiness adds up with other medicines, and what to tell your team before surgery.
Chapter 7: Adverse Effects & Risk Populations
Cannabinoid hyperemesis syndrome (CHS), cannabis use disorder, anxiety and heart effects, driving, children and edibles, and who should be extra careful.
Chapter 8: Product Quality & Sourcing
How to read a Certificate of Analysis (COA), what safety screening covers, warning signs, why licensed and tested products matter, and full-spectrum vs. isolate.
Where the Research Stands
Four pages that rate how strong the research is for common conditions, with the harms and unknowns next to each rating, plus questions to bring to your clinician.
Chapter 9: Talking to Your Care Team
Where the stigma came from, why people often don’t tell their doctors, the four things to share every time, and how to use the book with your care team.
References, Further Reading, Glossary, and two appendices
91 numbered references, further reading, a glossary of terms, chemical structures of common cannabinoids (Appendix A), and the sources for the cheat sheet (Appendix B).
Digital edition v1.4.3. Information current as of September 2026. Journal references were checked against PubMed.
A sample of the takeaways
Short passages from the book, so you can hear how it reads.
“The simple rule: don’t drive after using cannabis. Wait longer after edibles, and longer still if you also take a medicine that makes you drowsy.”
Chapter 7, Adverse Effects & Risk Populations
“Natural” and “non-intoxicating” don’t mean “no drug interactions.”
Chapter 6, Drug Interactions & Medication Safety. The chapter explains why, and why to ask your pharmacist or prescriber to check cannabis against everything you take.
“Match the batch number on the bottle or jar to the batch number on the report, a small habit that catches the most common mix-up: a report that looks fine but belongs to a different lot.”
Chapter 8, Product Quality & Sourcing
“The fair summary: the entourage effect is a reasonable idea that hasn’t been proven.”
Chapter 3, Terpenes and the Entourage Effect
The two-sided cheat sheet card
A pocket guide to the cannabinoids and terpenes you’ll see on Minnesota labels and lab reports (COA). Print it on both sides and bring it to the counter or to your next appointment.
Every entry carries a simple three-level evidence rating (stronger evidence, early research, or user reports only) and a short source line. The full source list is Appendix B of the book.
Side 1: Read the Label, Find Your Fit
- Four cannabinoids: THC, CBD, CBG, and CBN
- Six terpenes, with the smell to look for
- Counter tips on labels, strain names, and edible timing
- A “Safety first” box on driving, mixing sedatives, and when to get help
Side 2: Match My Day
- Four topics people often ask about (focus, sleep, pain, and appetite), with what the research does and doesn’t show
- How to read a jar
- A log to fill in and bring to your pharmacist or consultant

Is this medical advice?
No. Foundations is for general education. It isn’t a diagnosis or a treatment plan, and it doesn’t replace a conversation with a qualified healthcare provider. The author is not a physician, pharmacist, or other licensed clinician.
Will it tell me what to take, or how much?
No. It explains what published guidance says, so you can follow your clinician’s reasoning and ask better questions. It doesn’t give you a dose, a schedule, a target, or a product pick.
Is it only for Minnesota?
The book is written for adults anywhere, and it notes that cannabis laws vary by country and state. The cheat sheet card is built around Minnesota labels and the Minnesota medical program.
How current is it?
This is digital edition v1.4.3, current as of September 2026. Cannabis research changes quickly, and the book says so when a finding is early.
